The Bluetooth works well too.

Only gripe is that I bought the bluetooth version so that I could connect to my computer's bluetooth -- but that does not work, because you need the jabra bluetooth adapter dongle to connect via computer, even if your computer has a compatible bluetooth adapter -- all so Jabra can charge $50

Bluetooth is still good, but we experienced some (extremely slight) distortion

Great sound and the Bluetooth makes this awesome for meetings.
