Good and not so good 30

Most:
1) Correct operation of Bluetooth with two simultaneous sources (PC + personal Blackberry) well switch to incoming call reception despite music from the PC.
2) His very correct despite the minimalist helmet size
3) Good attenuation of ambient sound in noisy environment by double microphone (tested several times in noisy public places)

less:
1) The inner lining which disintegrates very quickly. for less unpleasant when wearing a white shirt, the problem obviously disappears when there is no lining ...
2) The battery will not hold more than 5 hours in music listening
3) The headset is comfortable but do not want on the head if you move too much or just simply tilt their heads to the ground. A book for users who are calmly walking or sitting quietly at their desks. Not even worth considering to run with!

I remain satisfied with my purchase, but it does not deserve more than 3 *
