For the mute function, there is no button on the TREBLAB XR800. You can do that on the phone or by pressing "Volume -" till you mute all the sound. Additionally, you can pause music using HOME KEY. To answer a call please make a short press HOME KEY one time.

What is the driver size for the XR800 ?

I notice when my XR800 earbuds are on, the only LED flashing is the one on my right ear piece. The LED light on the left ear piece lies dormant and never flashes. This in no way affects the sound quality of the music--which is excellent. I am fully satisfied with the fit and sound and everything about these earbuds, and they are truly top-quality at a good price. Still, I am wondering about that darned light! LOL!

Are the headphones still waterproof if the rubber USB port cover has fallen off?

Dear Zane,

Thanks for your inquiry. 

In case the rubber USB port cover has fallen off, it makes the earphones not sufficiently protected against water as spillages might occur thus causing a serious malfunction. Should we ever be of any other assistance to you, please, feel free to contact us. 

Best regards, Dennis | Customer Care Agent | Productech
