## Description

Worry-free, situationally-aware listening with open-ear Bluetooth headphones. Secure, comfortable over-ear hooks and 16.2mm drivers for immersive sound and powerful bass.

Review: seems good - These were for husband and he's been using them for running almost daily and seems to be still working fine after many months.
Review: Extremely happy with these - Great sound, good battery life. I believe the battery case is 800mah while others are 300-400. Only thing some people might not like is the case is on the big side but personally I like it. I also love how comfortable they are even with glasses 🕶️

## Questions & Answers

**Q: Are these comfortable for sleeping both on back or side? concern as the part that goes under ear looks plastic not silicon coated.**
A: Dear Customer, 

Thank you. We wouldn't recommend wearing the O1 earbuds for sleeping, especially on the side. They are on-ear and over-ear. It will not be comfortable for you to lie on the pillow on side. The Truefree T3 earbuds might be better for sleeping. 

Please feel free to contact us through Amazon message or here for any additional information needed.

**Q: Can others hear your music/audio?**
A: Dear Customer, 

Thank you. The Truefree O1 earphones adopt directional sound transmission technology to make sure the sound goes into your ears directly and dramatically reduces sound leakage. People who stand by you will not hear your music. 

Please feel free to contact us through Amazon message or here for any additional information needed.

**Q: What is the point of game mode? I understand the lower latency but why just have low latency standard? What benefit to turning it off?**
A: Game mode is to reduce latency when watching film such as games or TV. Game mode makes up for the delay in signal and helps to 'match up' what you see and what you hear. To do this, it has an effect on battery life, sound quality, bluetooth range and other items. Use Game Mode for visual and sound and turn it off for music.

## Customer Reviews

### ⭐⭐⭐⭐⭐ seems good
*by A***R on 4 February 2026*

These were for husband and he's been using them for running almost daily and seems to be still working fine after many months.

### ⭐⭐⭐⭐⭐ Extremely happy with these
*by X***A on 29 August 2025*

Great sound, good battery life. I believe the battery case is 800mah while others are 300-400. Only thing some people might not like is the case is on the big side but personally I like it. I also love how comfortable they are even with glasses 🕶️

### ⭐⭐⭐⭐ Better than their other models!
*by S***G on 23 October 2025*

I think these are way better than the other version. I tried the other version, and they didn’t work for me. However, these are more consistent, feel nicer on the ear, and work reasonably well for the price. If you're budgeting, these are great. If you have a bigger budget, I’d suggest spending more to get a better pair. That said, these are not bad! They do work, but I’m told they work better with Android than Apple. However, I am using them with Apple, and these ones are okay.
