Another point is related to the size that I can put my motorcycle helmet without problems, nothing bothers me. In addition it allows me to use the hands-free kit.
In terms of audio quality, everything seems to balance, not too much bass and treble okay, I use a Samsung galaxy S2 and mainly rock / metal, overall very satisfied!
Negative, I can not adjust the volume and my phone does not seem compatible with previous and next track controls (handsfree kit with only 1 button).
4 stars for me.
