Nice audio and great noise cancelling system

Superb Comfort

I can say that the comfort is superb for this piece. I ride a motorbike so I need to wear a helmet. It doesn't impede with the helmet and it stays in the ear throughout the journey. However, I must say that the earpiece isn't loud enough. Not sure if it's just my device or the apps that I use but I can't seem to get it to be anywhere near the loudness that I like. Maybe it's just me. Overall, this product is something that I would recommend.

Sounds great

These sound almost better than my $100 earphones!
