Review: Perfectly compatible with Apple wired headphones. - I’ve been looking for a solution to use my Apple headphones with my PC, and nothing seemed to work. I tried multiple headphone adapters, but none could fix the issue—until I got the MillSO USB to 3.5mm Audio Jack Adapter. It's absolutely perfect! It solved my problem, and now both my headphones and microphone work perfectly. At first, when I plugged in the Apple headphones, I didn’t push the jack in all the way, which caused the sound to cut in and out. So, I used a headphone extension cable to get sound, but then I realized it was just my mistake. Once I pushed the headphones fully into the adapter, the sound was crystal clear. I’m really impressed with MillSO’s product and will definitely keep an eye on their future offerings. I highly recommend it!

### ⭐⭐⭐⭐⭐ Works Exactly Like I Needed
*by E***S on May 20, 2021*

I purchased this to use when I want to listen to music on my computer using headphones. Prior to using this device I plugged the headphones into the port on my desktop speakers which works fine but is just not convenient. What I wanted and now have, is a way to switch from my desktop speakers to the headphones by using the sound setting on the task-bar so I don't need to plug and unplug the headphones. Why, cause I am lazy and want to be able to make the change while I have my feet up on the desk with my keyboard in my lap. I was not sure this device would do that based on the description, but I asked a question and someone confirmed it does work that way - thank you for that, which it does. It now shows up in the sound setting like a device which I was able to rename to "headphones" so I can easily switch my output device using the task bar sounds icon. As for the sound quality, it sounds about the same to me regardless if the headphones are plugged into the jack on the speakers, directly into the output jack on the motherboard or the new jack adapter. It's appears to be a well made device too. I purchased the longer cord so it's not braided like the shorter version, but it's a quality material that is soft and flexible. The extra length allowed me to wrap the cord around the base of one monitor stand to it's always available for easy access. Very pleased with this purchase and have no issue recommending it for anyone who plans to use it the same way I have described.
