## 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

### ⭐⭐⭐⭐⭐ Great ear phones. Just what I have wanted.
*by C***E on 7 July 2025*

I wear hearing aids so I cannot wear ear studs and have to wear bulky over ear headphones. These ear phones are great! They just sit over the ear and are so light and discreet. I use them to listen to podcasts while working in the garden and kitchen. So amazed at the long range when my tablet is actually sitting in the house while I listen with good clarity in the garden. Sometimes there is a little slag if I wonder a bit far from the house but the sound quickly picks up again. It is amusing that nobody notices that I am wearing them as they are covered by the hair!

### ⭐⭐⭐⭐⭐ Open ear headphones
*by P***P on 25 June 2025*

This is my second pair of these headphones, which I find very useful. It takes a little while to get the controls sorted (these can be adjusted in the app), but after that, plain sailing. I don't like, and can't wear in-the-ear ones, and these do the job nicely. Don't expect the same loudness as in-the-ear, but they are more than ample in volume (I wear mine all the time, and even on my bike), and of course you still have spatial awareness with other sounds. My first pair are still working, though after being dropped too many times (my fault, and the last time at some speed) they haven't reset quite right (which they always did on previous occasions). Recommended. Buy the ones that have been returned for a really good price, they are still in really good condition...

### ⭐⭐⭐⭐ Value for money & hits the spot
*by A***R on 9 June 2025*

Awesome headphones, great quality and great charge.Solid for the gym & commutingGreat value for money
