The best thing I like is the quality of construction. It feels solid and well finished. Excellent response to controls. I am not sure how much range it should work at but it works through walls upto 10-15 feet which is fine. Good sound quality, though with blue tooth maybe the phone does not support good bass. I like the wired operation too. can use it with my laptop or MP3 players.Only drawback, if you want to call it is that it looks a little gadgety with the earpiece bulging over your ear. But I am happy I bought this product!
