I have searched Kh I while working at your desk, at home or just outside can wear while walking and which hindered me no annoying cables, which guarantees always gets stuck somewhere.
Anticipation, the right earpiece roars audible at low volumes. What bothers me is that, because it just detracts from the overall impression, but I take it back. More importantly, the device otherwise good sounds and simple acts around. The battery lasts forever, after some fumbling they sit well (but are quite warm in the ear) and the operation is simple. Turning on, is good.
The scope of supply is modest. No power supply (Kh has microUSB), only a labbe engined jack cable, carrying case, that was it. As a power supply, however, is any USB charger.
It is positive that can be connected simultaneously to up to two devices. For me it is the Mac and my Android. Listen to music on your PC and still never miss a call, that's a big advantage of Kh. He also has a microphone, you can make calls without delay and in decent quality.
The price is sublime and I can understand anyone who does not want to spend so much money. Those looking for sound quality, the better looking elsewhere but if it should be wireless, the BOSE should come shortlisted.
