I purchased this with my iPhone and it sounded awful right away. They have a very impressive online demo, but it's not really accurate. This is actually the first headset I have had where people kept telling me they couldn't hear because of the wind noise.To top everything off, the ear claps broker while in my pocket. It's really flimsy, which you can probably tell by looking at. Don't let the term "Military grade" full you. Maybe the French military that never sees any action. Aliph doesn't list a number to call them, so I filled out a contact form about the broken ear clasp, which of course got no response.Don't buy this junk.
