"free A2DP firmware upgrade makes this the one to beat"5.0 starson by arthuraaron
Pros: Great sound
Clear to others, even with background noise
custom voices, and other web firmware twiddles
volume control with the free A2DP firmware upgrade!
listen to music, or other sound data, via the A2DP upgrade.
Cons: the in ear fit can be tiring, especially if you wear it a lot. switching ears solves this issue.
Summary: the key is the Web interface on this great Bluetooth.
Excellent device, provided it holds up--just got mine.
