TOZO Headphones Comparison TOZO O2 TOZO OpenEarRing TOZO NC9 TOZO T10

Review: Brilliant earphones. - These openear headphones are my first dip into this style. Whilst I will be using my TOZO NC3 as a reference point, this is not a companion review. I use headphones daily for the gym and am always looking for the perfect set. I was apprehensive on both sound quality and fit of these, not because of the brand but more so the design. I have worn these for some weeks now and put them through their paces in the gym. I initially found them fiddly to put on and get into the right position, mainly due to the more simple design I’ve been used to. However, after a couple of uses, it soon became second nature and now they just seem to slot into place. The sound quality is excellent and paired with the app, you can set your own preferences. I was surprised as to how clear they are especially given that they are not like the more traditional earbuds with silicone tips. They are not designed to, nor do they cancel out other noises. However, once these are positioned correctly, ambient and background noise is just that. You can concentrate on your music whilst still knowing what’s going on around you. These have not fallen out or moved during any workout and the functions are easily operated even with sweaty fingers. Having a slightly bigger surface area helps with this. Another benefit is no stress or irritation in your ear. I am sure this is also healthy and more gentle on hearing Battery life is very good and with the clear display on the case, you should be able to monitor when these need charging. You also get a nice little repeated noise in your ear once the charge is too low. Connection to Bluetooth was easy and worked first time. For me, it still comes down to what type of workout I’m doing, whether there’s any classes and excess music in the background as to which ones I wear. I always keep both in my bag so I have a choice. Another good choice.
Review: Far Better Than Expected - I’ve been using these headphones for a while and they’ve turned out better than I expected. The open-ear design is comfortable and avoids the pressure you get with in-ear buds. The adjustable hooks make them secure without being awkward, and once you’ve worn them a couple of times they just slot into place naturally. Sound quality is solid. Vocals are clear, bass is present without being muddy, and they work well for both music and podcasts. They don’t block out background noise completely, but that’s part of the design. It’s actually useful when running or working in shared spaces because you stay aware of what’s going on around you. Battery life is strong. A short charge gives hours of use, and the case display makes it easy to keep track of power levels. They last through a full day without issue, and the quick-charge feature is genuinely handy when you’re about to head out. Build quality feels good. They’re lightweight but sturdy enough for daily use. The app integration adds flexibility with EQ settings, which is nice if you want to fine-tune things. Overall, they balance comfort, practicality, and performance. They’re not trying to be premium studio gear, but for everyday use they’re excellent value. I’d recommend them to anyone who wants headphones that don’t dig into your ears, stay put during exercise, and deliver clear, balanced sound without breaking the bank.

### ⭐⭐⭐⭐ Very good quality
*by A***Y on 31 July 2026*

These are very good. Battery charge lasts a while, even when they've not been used for ages. Sound quality is very good. Just a little bit annoying when they slip out of your earhole, as this will make one of the buds turn off.
