My much-more-expensive Motorola Bluetooth device was irritating, for a number of reasons. One, the slim and sharp-edged hook over the ear competed with my glasses bow and consistently hurt my ear, meaning I took it off more than I left it on. This one clips to my collar, works perfectly, and cost about a third the price of the Motorola one. It also comes with a tether to hang around the neck if you want to keep it relatively unseen. Excellent product.ADDENDUM: So tell me, why is it whenever you find something that does precisely what you were looking for, it becomes unavailable? Sigh....
