Review: Impressive Sound & Comfort! - I’ve been using the TRUEEFREE O2 Buds for a while now, and they have exceeded my expectations! The sound quality is crisp, with deep bass and clear highs, making music and calls a pleasure. They fit snugly and comfortably, even during long listening sessions. The battery life is great, and the charging case is super convenient. Overall, a fantastic pair of earbuds for the price—highly recommend!
Review: Lightweight and sounds great - I have been using this open-ear earbud for almost two weeks now and these are comfy and sound great even when it's away from the ear. Feels unrealistic when you think about how you can hear bass well even when it's not in-ear. Battery life is good for work use, I have used it for 1 full day without the battery getting low. The best part is even when u sleep and forget to remove the earbuds, you won't even know it's there as it's lightweight and it does not hurt your ear.

### ⭐⭐⭐⭐ Good overall
*by T***. on 12 October 2024*

This product surprised me with the immersive sound without blocking exterior noise, they work really well and battery life is amazing. I also use them a lot in the office for calls and listening to music, without losing awareness of what's happening around me. They are very light which means I can use them for extended hours with no pain or uncomfortable feel in my ear. Controls work really well and have different functions, other similar products only change song or play/pause, but these also control volume and voice commands to Siri or alike. Never been able to go 100% on volume, they sound really well and with the customized equalizer you can adjust to your liking. My only concern is if I use them while running or cycling, I fear they may fall. Haven't tried it though.
