Very good for a 36" high (90cm) desk. I have used a lot of headsets in my life - ranging from Bluetooth to wired to Apple to JBL - you name it. But if you are intending to use it on a North American carrier, call the carrier before ordering the phone to make sure that they will actually support the bands. It is now obvious that they are made extremely cheaply. Every aspect of these shoes has been perfect. The app is nifty and responsive. Ordered for our daughters birthday. If it breaks, which seems would be a possibility, the unit will be of no use. Only gripe, is the ridiculously large how to wash tag down one of the sides. If youre a 10, youll definitely want to size up.
