Here’s what I was looking for and what I found: Main objective: Use a BT receiver to allow me to use wired high quality headphones (Sennheiser HD650, HD598, HD555 mod to 595) with BT enabled devices (TV, computers, iPhone 7+, iPods and iPads) and secondary objective of using wired headphones with non-BT enabled legacy devices (iPod classic, older TVs) Why? Good quality BT enabled headphones are expensive and have a limited frequency range (Bose QC35 $349, and Sennheiser HD-1 Wireless $499, 28 ohm impedance, 16-22000 Hz) compared to higher quality headsets (Sennheiser HD650 300 ohm impedance, 10-41000Hz; HD598 50 ohm, 12-38,500 Hz, HD280 64 ohm, 8-25000 Hz). Even though BT has improved up to BT 4.2 and codecs for sound transmission have improved to decrease latency and transmit a broader range of frequencies, it is still cheaper to convert wired headset to BT capability at the inconvenience of managing a dangling cable. I don’t expect the BT transmission to have the same quality as a headphone wired directly to a receiver or iPhone/iPod/iPad Why did I purchase both? a. Reviews of many bluetooth (BT) receivers (Rx) used to drive headphones reported lag between video and audio. I wanted the receiver, but if there was going to be lag, then I’d pair the Rx/Tx with the Rx to see if that helped. I looked for low latency drivers. b. For non-BT devices (old iPod classic, non BT TV, I needed a BT Tx, so a combo Rx/Tx made sense. What features were I looking for? a. Volume control on the Rx. Why? because the wired headphones don’t have volume control unless I put a volume control between them and the Rx. Samsung Series 6 600D and Series 7 700D UHDTVs with BT don’t provide volume control using the TV remote; therefore the receiving end of the BT Rx has to control the volume. b. Most up to date BT 4.1 or 4.2 so that it maintains backwards compatibility with other BT units (not all BT are the same — i.e. my iPhone 7+ can pair to a Jaybird Freedom, but my iWatch series 2 won’t pair with the Jaybird Freedom). My intended uses: 1. Pair Bluetooth TV to Rx connected to headphone, if there is latency, then connect Rx/Tx to TV RCA outs and pair Rx/Tx to Rx connected to headphone 2. Pair iPads/iPhone/iPod blue tooth to Rx/Tx in Rx mode or Rx connected to headphone 3. Pair Rx/Tx to Rx connected to headphone DESIGN. Both have the same small form factor, plastic box except the Rx has an on off sliding switch rather than just a single button that has to be held 3 seconds to turn it on. Rx/Tx no sliding on off switch, just a button that has to be held down 3 seconds. EASE OF CONNECTION: Charged both fully. Tx/Rx set to Tx and turned on, Rx turned on 1st time and they paired within 5-10 seconds. Tx/Rx goes to solid blue; Rx goes to LED off blinking blue every 10 seconds instead of solid blue to indicate connection. No I can connect any nonBT device (TV, older iPods, iPod Classic) via male to male 1/8” plug to the Tx/Rx set to Tx mode and headphone connected to Rx and I have a functioning BT system. I just wrap the headphone cords up with velcro and put it on one side of the headband … looks geeky but I’m using it for function, not looks. To set either unit to pair, just double tap the “power button” and they immediately blink red blue red blue until paired. Once paired, Tx/Rx light goes to solid blue, Rx blinks blue every 10 seconds. Even if a connection is active, the double tap “power button” breaks the connection and sets the units to pair mode. Pairing is quick. Pairing to Samsung 600D, 700D UHDTV is easy. Go to Menu Settings > Audio > Select Speaker > Bluetooth. The Trond unit will show up no screen, select pair and it’s done in 5 seconds. Volume control is on the Trond unit; Samsung remote cannot control volume from TV. NO LATENCY on both TVs to Rx/Tx or Rx. Very nice. Don’t need to implement the Rx/Tx —> Rx method. This gives me a BT Rx for each TV now. Caveat, iWatch series 2 cannot pair to either Trond Rx/Tx set to Rx mode or Trond Rx. But iWatch series 2 cannot pair to Jaybird Freedom BT earphone. iPhone 7+ pairs to Tronds and Jaybird Freedom BT and work without problems. This seems to be more of a problem with the iWatch than the Trond units. DROP OFFS and DISTANCE: Connection good to HDTV BT 30 feet away unobstructed. No drops offs of signal or loss of connection with iPhone in pants pocket and received on opposite side of my head indoors. Haven’t tested outdoors where BT can’t bounce off walls. Intermittent breakup when BT Rx separated from BT Tx by a floor (i.e. receiver on 1st floor, Tx in basement, but of course it gets better when I’m standing 1 floor immediately above the Tx in the basement). If paired to iPhone 7+ and I turn on the car to which the 7+ is paired, the Trond connection shuts off and the car and 7+ become paired to give priority to car-phone handsfree connection. Trond doesn’t have a speaker and can’t be used for answering calls (which is not what I got this for). SOUND QUALITY: No lag from Samsung UHDTV Series 6 and Series 7 using the TVs BT. No audio-video lag between TV and Trond Rx, iPad and Trond Rx playing movies on desertcart Prime and Youtube. Sound quality depends upon type of headphone connected to Rx, but the Rx and Rx/Tx can both drive a 300 ohm impedance Sennheiser HD650 without problem. (Avantree Quick Clip reportedly has a hiss and can’t drive anything more than 32 ohm from what I’ve seen on reviews on desertcart). The sound quality (frequency spread) is not as wide as wiring the HD650 directly to my iPod classic, but it’s almost as good (i.e. like listening to an MP3 at 320 kbps instead of a lossless MP4/M4A at up to 1444 kbps sampling). I use MP4 lossless music files as I can hear the difference in quality between 1444 kbps sampling MP4/WAV and MP3 320 kbps max. I am very satisfied with the BT performance from iPhone 7+ to Trond Rx to HD650, and iPod Classic to Trond Rx/Tx to Trond Rx to HD650. Even though reviews say an HD650 is best used with an external amp, I have been more than satisfied with the performance with an un-ampped HD650 driven by an iPod classic or iPhone 7+ lightning to 1/8” plug given the type of recordings I use (which are much better than the 128 kbps stuff found off of iTunes music store … the stuff that many are satisfied using less refined headsets and earbuds). Works just fine with the other HD598, HD 555 mod to HD 595, so it should work just fine with anything lesser. Even the slightly truncated sound of the Tx/Rx to HD650 is still better than any of the other headsets. Wired is always better than BT, but BT is getting close. Other specs: HD280 8-25000 Hz, 64 ohm impedance HD555 12-38599 Hz HD598 12-38500 Hz, 50 ohm HD650 10-39500 Hz, 300 ohm HD1 16-22000 Hz, 28 ohm; this is Sennheiser’s $499 BT headset Bose QC35 $349, QC2, QC3 — I can’t find specs on these, but the Trond’s drive my QC3 just fine. Haven’t tested QC2 and of course the QC35 doesn’t need this. In general, Bose headphones tend to muddy the mids and are thus more bass heavy than balanced headphones. Sennheiser HD700 8-44000 Hz, 150 ohm, $419 Sennheiser HD800 19-44900 Hz, 300 ohm, $990 I’d rather spend my money on an HD700 than on the $499 HD1, so the Trond BT are a workable solution for me. If they can drive the HD650, I’d anticipate it should do just as well with an HD700. Things I haven’t tested: I haven’t tried the Rx/Tx bind to two Rx to drive two headphones, but this is what would be needed to drive 2 headsets from one TV. I haven’t tested how week the signal would get from an Rx connected to a 1/8” splitter to drive two headsets. FINAL THOUGHTS: 1. Trond Rx/Tx and Rx are both 5 star. 2. BT pairing is easy, quick and simple. 3. No lag between audio and video from Samsung UHDTV BT to either Trond unit. 4. Trond Rx able to drive 300 ohm Senheisser HD650 without hiss 5. Less cost than the Avantree Quick Clipper Pro and Priva III (which I considered prior to purchasing these). Reportedly the Clipper can’t drive anything >32ohm per specs. If you don’t need a BT Tx, then I’d just buy the $20 Trond BT Rx. If you want flexibility, then get the Trond BT Rx/Tx with volume control which are $37 as of 3/20/2017. Even though iPhone and iPod Classic can control the volume transmitted to the Rx, the Samsung TVs don’t; therefore, I wouldn't get the BT Rx/Tx without volume control or volume at the headset will be loud unless you put a volume control between the Rx and the headset plug. 3/24/2017 Update: I liked these so much, I bought another pair of Tx/Rx and Rx. desertcart had a lightning deal on the Tx/Rx for around $25. Great deal. To get them to initially pair, make sure no other BT devices are on. I couldn't get them to pair initially when my BT Samsung UHDTV was on because the TV seems to automatically pair to devices like this. Once I turned off the TV, I could get the Rx/Tx to pair to the Rx. After that, pairing was quick as long as the two were in near contact with each other though other BT devices were on. Update: 4/10/2017 When using these with a sensitive, low impedence in ear monitor -- Shure PTH500/530, there is background noise when played at low levels; the Shure can play really loud at a lower volume setting than >50ohm impedance headphones (i.e. No low level noise using Sennheiser HD280 (64 ohm), HD 555/598 (50 ohm), HD 700 (150 ohm), and HD 650 (300 ohm). Paired to Samsung Series 6/7 UHDTVs as well has headphone output on a Yamaha RX-3060 receiver running a connected BluRay, I find no lag between audio and visual, even after putting the movie through various digital signal processes on the Yamaha. Review: Real low latency transceiver - I have been on the hunt for a low latency transceiver and a headset combo. This one fits the bucket. First let me state that the endeavor is more complicated than it seems at fisrt hand. Although bluetooth tries to make it as easy and transparent for the user, not all bluetooth devices are equal. What you want to pay attention to is what codecs are supported by your devices. There are fast codecs and slow codecs, and there are high fidelity codecs and low fidelity codecs. Without going too much into it, the fastest high fidelity codec available today is called AptX-LL. It is an improvement over the older AptX codec, of the same company. So what you want is a transmitter and a headset that both support AptX-LL. AptX alone is not fast enough, mind you, so if anything is AptX only, your bluetooth connection will be noticeably slower. Then, there is the issue that sometimes a certain brand of transmitter and a certain brand of headphones will not connect fast even when both support AptX-LL. This is annoying, but it happens. So you want to try a few headsets with a few transmitters and see which ones work together. And that's what I did. I bought a bunch of transmitters and a bunch of headphones and paired them all to see what would work. In the case of this little device, it worked fine with the following headsets: Premium MS301 Mixcder Wireless & Wired V4.2 Bass Noise Isolation Headphones with aptX Low Latency Audio- Headset with Mic & Bluetooth - Sturdy Foldable - Universal Compatibility for iPhone Tablet PC Avantree Wireless Bluetooth Over Ear Headphones with Mic, LOW LATENCY Fast Audio aptX Headset for Gaming TV PC, 40h Battery Sound - Audition Pro [2 Years Warranty ] Premium MS301 Mixcder Wireless & Wired V4.2 Bass Noise Isolation Headphones with aptX Low Latency Audio- Headset with Mic & Bluetooth - Sturdy Foldable - Universal Compatibility for iPhone Tablet PC And an older version of Plantronics BackBeat Fit Wireless Headphones - Retail Packaging - Green The plantronics FIT headsets are not consistent. If the box says is "sweatproof", the headset will be fast. But if the box says it's "waterproof", it's a newer, improved version of the headset that does not work as fast, for some reason. The newer model phones also failed with other transmitters. Plantronics improved the case and weatherproofing, but made the electronics slower in the process. But that's for another review. It is important to note however that Platronics does not claim to support LL, so no fault on them. In any case, this transmitter is a true low latency transmitter/receiver that works with most of the headsets I bought. The one headset this transmitter did not work with did not state to support low latency, so that was to be expected. You will notice that my list does not include fancier headsets from beats, bose, etc. That is because the higher end manufacturers are being slow to adopt Aptx-LL, for some reason. I have not seen a higher end headset that supports it. Also I was not going to spend $200+ on a headset for this test, to be honest ... Now, if you have a sweetheart headset, do not worry. Buy two of these little guys and set one on your TV as transmitter and the second one on your phones as receiver. They will pair so fast you will think there is still a cable connecting your equipment. Ok maybe not so much but really, the delay will be negligible. Much better than AptX alone. Three times better, not exaggerating. Other than the latency, which was my pet peeve, other aspects of the device make it desirable. The construction seems nice, small and durable. It is light however. And it can run on transmitter mode while connected to a power supply, which is another nice thing. Three buttons (+), (-) and (POWER/PAIR) along with a TX/RX selector make the operation really simple. All in all, this is a low risk purchase, well worth the money if you are trying to improve your video and audio sync. Just be aware of the nuances of bluetooth protocols and nuances, and you will be happy. Non-relevant technical detail: For those of you that want to know, sometimes manufacturers says which chipset they use in their products. A popular chipset that supports AptX-LL is called CSR 8670. If you see products with that chipset, it's a good clue they will support low latency. When I say the chipset mentioned in this page I know these were fast. Another non-relevant technical detail: Latency is measured in thousandths of seconds, or milliseconds. In my experience, anything rated 100mS or more will have a very noticeable delay, and anything rated 30mS or less will give you audio almost right on top of your video. The less the better of course, but at the 30mS mark you will have to pay close attention to notice delay. So you can watch out for that clue, if mentioned, when deciding what to buy. Good luck! ## Features - APTX and APTX LOW LATENCY SUPPORTED. Powered by premium CSR8670 chipset, TROND BT-DUO S not only supports the latest Bluetooth V5.0, but also adds aptX and aptX Low Latency to both the TX and RX modes. With aptX, you can enjoy CD-quality sound wirelessly over Bluetooth connections with aptX-source devices like TV, phones or tablets; with aptX Low Latency, you can now watch video while listening to wireless audio in a synchronized fashion AND without any noticeable audio delay - TX MODE: BLUETOOTH TRANSMITTER. By plugging TROND BT-DUO S to your non-Bluetooth audio sources (TV, iPod or Kindle e-Book reader), you can enjoy high quality music wirelessly or listen to late night shows without disturbing your family members on your Bluetooth headphones or speaker. Please also order TROND TD-BH01 Over-Ear Bluetooth V4.2 Headphones (ASIN: B075VLWPXF) for the best low latency performance - RX MODE: BLUETOOTH RECEIVER w/ VOLUME CONTROL. TROND BT-DUO S can upgrade your old wired headphones (such as Bose QC25/QC15) or speakers into wireless with the support for aptX Low Latency. Its volume/track buttons allow you to play/pause music, turn volume up/down, and select track forward/backward. (NO hands-free calling due to lack of microphone; cannot be powered up automatically while you start the car ignition) - PAIR WITH TWO and SMART CODEC INDICATOR. In TX mode, TROND BT-DUO S can pair to two Bluetooth Headphones, and streams audio to both simultaneously. However, in this application, the codec will be downgraded to from aptX Low Latency to SBC. It can also tell you which codec is in place by displaying different LED status. The blue LED blinks once every 10 seconds for SBC, blinks twice for aptX, and blinks three times for aptX Low Latency - What You Get: TROND BT-DUO S 3.5mm Bluetooth V5.0 Transceiver with aptX Low Latency, 3.5mm male to 3.5mm male aluminum audio adapter, 3.5mm male to 3.5mm male audio cable (50cm extra-long), 3.5mm female to RCA male audio cable, USB to micro USB charging cable, user manual in English ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01K8ANDCI | | Best Sellers Rank | #199,243 in Electronics ( See Top 100 in Electronics ) #223 in Audio Component Receivers | | Brand | TROND | | Built-In Media | Transmitter Receiver | | Color | 2-in-1 BT V4.1 Transceiver w/ Volume Control | | Compatible Devices | [Bluetooth-enabled devices] | | Customer Reviews | 4.2 out of 5 stars 1,196 Reviews | | Data Link Protocol | Bluetooth | | Hardware Interface | Bluetooth, Bluetooth 5 | | Item Dimensions L x W x H | 2.17"L x 1.5"W x 0.41"H | | Item Weight | 17.28 g | | Manufacturer | TROND | | Mfr Part Number | BT-DUO S (Black) | | Model Number | BT-DUO S | | Product Dimensions | 2.17"L x 1.5"W x 0.41"H | | Warranty Description | All TROND products Warranty - 18 months and 30-day money back .

And TROND BT-DUO S has a slightly bigger battery of 200mAh, whereas BT-DUO has the 160mAh battery.Regards,TROND Customer Care **Q: What is the range of this device, i.e., how far away can a transmitting or receiving device be from the adapter?** A: This is actually a two fold answer. The quality of the headphones have an effect too. Between etrond's first transmitter and the new one, using Bluedio's UFO Pro's, their second adapter reaches at least 15' further using the same pair of headphones. They are both running bluetooth 4.1 and aptX. If you use and older version of bluetooth, your distance may be altered. I love the gained distance I get with etrond's new transmitter /receiver. **Q: When does Trond anticipate incorporating the new Bluetooth V.5 into its devices?** A: The SIG association is promoting the concept of Bluetooth V5.0 at this stage. However, it still take quite some time for manufacturers to design related products around the Bluetooth V5.0 chipset. Therefore we don't have any specific schedule for any Bluetooth V5.0 related products yet. Thank you for asking though.Regards,TROND Customer Care **Q: is it compatible with jaybird X2 and the bluebird X?** A: I would imagine it could. It hooked right up with my Bose QC30 set with no problem. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My detailed review of a great little bluetooth transmitter and receiver at a great price. *by M***A on March 20, 2017* Review of the following two items purchased together: Tx/Rx: TROND Bluetooth V4.1 Transmitter Receiver / Wireless 3.5mm Audio Adapter with aptX Low Latency & aptX for Both TX & RX, Dual Stream and Volume Controller Rx: TROND 3.5mm Bluetooth V4.2 Audio Receiver Adapter with AptX Low Latency & Volume Control, for Home Stereo, Wired Headphones & Speakers Both are 5 stars IMO.

Even though reviews say an HD650 is best used with an external amp, I have been more than satisfied with the performance with an un-ampped HD650 driven by an iPod classic or iPhone 7+ lightning to 1/8” plug given the type of recordings I use (which are much better than the 128 kbps stuff found off of iTunes music store … the stuff that many are satisfied using less refined headsets and earbuds). Works just fine with the other HD598, HD 555 mod to HD 595, so it should work just fine with anything lesser. Even the slightly truncated sound of the Tx/Rx to HD650 is still better than any of the other headsets. Wired is always better than BT, but BT is getting close. Other specs: HD280 8-25000 Hz, 64 ohm impedance HD555 12-38599 Hz HD598 12-38500 Hz, 50 ohm HD650 10-39500 Hz, 300 ohm HD1 16-22000 Hz, 28 ohm; this is Sennheiser’s $499 BT headset Bose QC35 $349, QC2, QC3 — I can’t find specs on these, but the Trond’s drive my QC3 just fine. Haven’t tested QC2 and of course the QC35 doesn’t need this. In general, Bose headphones tend to muddy the mids and are thus more bass heavy than balanced headphones. Sennheiser HD700 8-44000 Hz, 150 ohm, $419 Sennheiser HD800 19-44900 Hz, 300 ohm, $990 I’d rather spend my money on an HD700 than on the $499 HD1, so the Trond BT are a workable solution for me. If they can drive the HD650, I’d anticipate it should do just as well with an HD700. Things I haven’t tested: I haven’t tried the Rx/Tx bind to two Rx to drive two headphones, but this is what would be needed to drive 2 headsets from one TV. I haven’t tested how week the signal would get from an Rx connected to a 1/8” splitter to drive two headsets. FINAL THOUGHTS: 1. Trond Rx/Tx and Rx are both 5 star. 2. BT pairing is easy, quick and simple. 3. No lag between audio and video from Samsung UHDTV BT to either Trond unit. 4. Trond Rx able to drive 300 ohm Senheisser HD650 without hiss 5. Less cost than the Avantree Quick Clipper Pro and Priva III (which I considered prior to purchasing these). Reportedly the Clipper can’t drive anything >32ohm per specs. If you don’t need a BT Tx, then I’d just buy the $20 Trond BT Rx. If you want flexibility, then get the Trond BT Rx/Tx with volume control which are $37 as of 3/20/2017. Even though iPhone and iPod Classic can control the volume transmitted to the Rx, the Samsung TVs don’t; therefore, I wouldn't get the BT Rx/Tx without volume control or volume at the headset will be loud unless you put a volume control between the Rx and the headset plug. 3/24/2017 Update: I liked these so much, I bought another pair of Tx/Rx and Rx. Amazon had a lightning deal on the Tx/Rx for around $25. Great deal. To get them to initially pair, make sure no other BT devices are on. I couldn't get them to pair initially when my BT Samsung UHDTV was on because the TV seems to automatically pair to devices like this. Once I turned off the TV, I could get the Rx/Tx to pair to the Rx. After that, pairing was quick as long as the two were in near contact with each other though other BT devices were on. Update: 4/10/2017 When using these with a sensitive, low impedence in ear monitor -- Shure PTH500/530, there is background noise when played at low levels; the Shure can play really loud at a lower volume setting than >50ohm impedance headphones (i.e. No low level noise using Sennheiser HD280 (64 ohm), HD 555/598 (50 ohm), HD 700 (150 ohm), and HD 650 (300 ohm). Paired to Samsung Series 6/7 UHDTVs as well has headphone output on a Yamaha RX-3060 receiver running a connected BluRay, I find no lag between audio and visual, even after putting the movie through various digital signal processes on the Yamaha. ### ⭐⭐⭐⭐⭐ Real low latency transceiver *by J***D on June 30, 2017* I have been on the hunt for a low latency transceiver and a headset combo. This one fits the bucket. First let me state that the endeavor is more complicated than it seems at fisrt hand. Although bluetooth tries to make it as easy and transparent for the user, not all bluetooth devices are equal. What you want to pay attention to is what codecs are supported by your devices. There are fast codecs and slow codecs, and there are high fidelity codecs and low fidelity codecs. Without going too much into it, the fastest high fidelity codec available today is called AptX-LL. It is an improvement over the older AptX codec, of the same company. So what you want is a transmitter and a headset that both support AptX-LL. AptX alone is not fast enough, mind you, so if anything is AptX only, your bluetooth connection will be noticeably slower. Then, there is the issue that sometimes a certain brand of transmitter and a certain brand of headphones will not connect fast even when both support AptX-LL. This is annoying, but it happens. So you want to try a few headsets with a few transmitters and see which ones work together. And that's what I did. I bought a bunch of transmitters and a bunch of headphones and paired them all to see what would work. In the case of this little device, it worked fine with the following headsets: Premium MS301 Mixcder Wireless & Wired V4.2 Bass Noise Isolation Headphones with aptX Low Latency Audio- Headset with Mic & Bluetooth - Sturdy Foldable - Universal Compatibility for iPhone Tablet PC Avantree Wireless Bluetooth Over Ear Headphones with Mic, LOW LATENCY Fast Audio aptX Headset for Gaming TV PC, 40h Battery Sound - Audition Pro [2 Years Warranty ] Premium MS301 Mixcder Wireless & Wired V4.2 Bass Noise Isolation Headphones with aptX Low Latency Audio- Headset with Mic & Bluetooth - Sturdy Foldable - Universal Compatibility for iPhone Tablet PC And an older version of Plantronics BackBeat Fit Wireless Headphones - Retail Packaging - Green The plantronics FIT headsets are not consistent. If the box says is "sweatproof", the headset will be fast. But if the box says it's "waterproof", it's a newer, improved version of the headset that does not work as fast, for some reason. The newer model phones also failed with other transmitters. Plantronics improved the case and weatherproofing, but made the electronics slower in the process. But that's for another review. It is important to note however that Platronics does not claim to support LL, so no fault on them. In any case, this transmitter is a true low latency transmitter/receiver that works with most of the headsets I bought. The one headset this transmitter did not work with did not state to support low latency, so that was to be expected. You will notice that my list does not include fancier headsets from beats, bose, etc. That is because the higher end manufacturers are being slow to adopt Aptx-LL, for some reason. I have not seen a higher end headset that supports it. Also I was not going to spend $200+ on a headset for this test, to be honest ... Now, if you have a sweetheart headset, do not worry. Buy two of these little guys and set one on your TV as transmitter and the second one on your phones as receiver. They will pair so fast you will think there is still a cable connecting your equipment. Ok maybe not so much but really, the delay will be negligible. Much better than AptX alone. Three times better, not exaggerating. Other than the latency, which was my pet peeve, other aspects of the device make it desirable. The construction seems nice, small and durable. It is light however. And it can run on transmitter mode while connected to a power supply, which is another nice thing. Three buttons (+), (-) and (POWER/PAIR) along with a TX/RX selector make the operation really simple. All in all, this is a low risk purchase, well worth the money if you are trying to improve your video and audio sync. Just be aware of the nuances of bluetooth protocols and nuances, and you will be happy. Non-relevant technical detail: For those of you that want to know, sometimes manufacturers says which chipset they use in their products. A popular chipset that supports AptX-LL is called CSR 8670. If you see products with that chipset, it's a good clue they will support low latency. When I say the chipset mentioned in this page I know these were fast. Another non-relevant technical detail: Latency is measured in thousandths of seconds, or milliseconds. In my experience, anything rated 100mS or more will have a very noticeable delay, and anything rated 30mS or less will give you audio almost right on top of your video. The less the better of course, but at the 30mS mark you will have to pay close attention to notice delay. So you can watch out for that clue, if mentioned, when deciding what to buy. Good luck! ### ⭐⭐⭐⭐ Awesome device *by D***D on July 19, 2019* I have a PC with a Creative SoundBlaster ZxR. Great card. I know people think there isn't a difference between built in audio vs sound card, but the difference is night and day and there's no way I would go back to built-in. The reason I bought this device is so that I could connect my Bose QC35 to it to and be able to enjoy the nice audio coming out of the sound card. Using a USB dongle for audio sucks, and this little device was the perfect solution. When I first had this, there was an issue. The sound would fade in and out when playing audio with low volume. I contacted the seller and they listed some steps on how to reset the device. After doing so, the fade in and out issue resolved. Since then, sound quality is as good as you can get with bluetooth. The only issue I have with it that prevents it from being a 5 star is that it sometimes takes 30 seconds to finally connect to my Bose or any other BT headphones that I have. Highly recommended for those who have soundcard installed into their PC and want to continue utilizing the card while listening to audio via bluetooth. ## Frequently Bought Together - TROND Bluetooth 5.0 Transmitter Receiver, Bluetooth Adapter for TV, 2 in 1 Wireless Audio Transmitter for PC MP3 Gym Airplane, Receiver for Speakers Headphones Boat Car - 12V Sealed Lead Acid (SLA) Battery Charger 1300mA, with Short Circuit Protection --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/33036313-trond-bluetooth-v5-0-transmitter-receiver-2-in-1-wireless](https://www.desertcart.no/products/33036313-trond-bluetooth-v5-0-transmitter-receiver-2-in-1-wireless) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-19*
