Convenient, but not enough miniaturized and expensive.

True wireless headset that gene but three flaws:
- It is relatively expensive (almost 200)
- The atria, although quite small, are still quite impressive for an ear
- And above all .. there is a beep with each change of volume! Very unpleasant when listening to music .. So it is expensive to take beep in the ear :)

I have not talked about the positive but:
-Very good autonomy announced (10am is usually 4 hours to this size)
-The sound quality is good, although at times (when the spectrum is broad, severe acute + simultaneously) a small breath means, but it is related to Bluetooth technology I think (ditto on the Philips SHB9100)
