This unit works well and does almost everything I need. I use it with my iPod shuffle and it is small enough to velcro to the back of it. Works great with my Motorola S9 headphones (which are also outstanding!). It has pretty good range, although it seems to be very defined. You can almost draw a line on the ground where the reception changes from perfect to non-exsistant.The only thing I don't like is echoed in the other reviews here. You cannot use this device while it is charging. Not sure why they made it that way, but it does have a pretty long charge (longer than my headphones). That feature would give this a 5 star rating from me.P.S. for those that wondered about pairing with headphones other than Jabra - my motorola S9's require a passkey and this device has no entry buttons or display. However, the passkey for all of Jabra's BT headphones (and this device) is '0000' (I confirmed this with Jabra tech support.) Since that is the same that Motorola uses, they have no problems pairing right up.
