Short & sweet. I bought this because it was a good deal and the reviews were decent. The headsets I owned before this were... The Jawbone (Original) which had great audio and battery, but was uncomfortable and unpocketable. Then, the blueant Z9 serviceable comfort, bad sound and lost, due to the unstable built in clip. Moving on to the next victim.
In it's defense, this headset is the most comfortable I've ever owned. Bad news? The battery life is unforgivably short. The audio is mediocre. If you're in a quiet place, it's fine. Add ambient noise and the party is over. Also, should you lose the cleverly designed charging case, there is no longer a way to charge it. Had I known this before, it would have been a pass.
Spend a few extra bucks.
This one's a pass.
