I just got my jawbone today but before I start to use it, I am already unsatisfied with following reasons:1. The crescent hole of the USB connector doesn't attach to jawbone securely! The headset keeps disconnecting from the charge cable. So it can't steadily stay in charge.2. The length for the earbud is not long enough to stay inside the ear, and another reason for this is because the back of Noise Shield area is so thick that somehow not allow your earbud insert deeper to your ear.3. With earloop installed, it's so hard to wear the jawbone even I've tried other sizes came with box.(There are 4 earloops they provide, 2 sizes "standard" & "long" for left & right side)Basically I haven't started to try the sound quality but honestly, I felt very disappointed with this due to the reasons above.(The charge connector keeps disconnect from jawbone while I am writing my comments now....)Don't waste money on this one, I'm really regret now for given up my previous choices (jabra & plantronics).
