I have been using the JB2 for about a month now, and I wasn't able to use it/them at all times. The first one had a bad earpiec speaker, which made the sound very crackly (something that often occurs with a poor bluetooth connection or implimentation so it was hard to dicern) and even ALIPH said, just return it to ATT (the only place one could get them at the time) and swap it out - known issue.

The second one, I couldn't get the volume high enough.

Fit CAN be an issue, because the device MUST HAVE the activity sensor touching your cheek. It JUST doesn't work at all unless that is the case. It isn't a question of it not working WELL if it doesn't, barely NO sound comes through if it isn't touching your face. On the one hand, this is great because ONLY what it can relate to the sound coming through the two micro microphones is transmitted as actual caller sound, but on the other hand one's VOICE gets filtered if the unit cannot properly compare it to the sound vibrations.

When it works and it fits, it works pretty darn well. I think the previous generation had better sound in the earpiece, I am still not happy with the sound in my ear. But, callers say that the sound is excellent. Very rich, strong signal and volume and not a lot of background noise.

Except for wind. I cannot even open the window in my car, and not have the wind COMPLETLY destroy the entire call. It isn't even a question of it being garbled, there is just NO discernable voice call coming through. I have tried calling MY HOME and leaving a voice mail on the AW, and even I cannot understand what I am saying when there is wind.

So, windows must be up. but, walking down a busy street, standing in a starbucks, being outside when the plane is turning up the engines, even the obligatory LAWN MOWER test my callers could BARELY tell that anything else was going on.

The earpiece on my mogul, treo, KRZR and iphone ALL sound better to ME in the ear than the JBII headset, but that really isn't the whole purpose of the unit. What with the new CA law going into effect TODAY for requiring headsets, I'll stick with it.

All in all, probably one of the best, if not THE best headphones.

Just a note on pricing. The original one I bought was full boat, 129$ OUCH! but, with about two weeks ATT had them for 95$, (83$ with my disc). I think we'll see them by July in the 85-95$ range, or LESS.
