This is actually my second purchase of the Plantronics Bluetooth-I bought the first one for my husband & loved it when I tried it out. The sound quality is fantastic, even when he's driving down the road in his big truck. Very comfortable & comes with 3 sizes of earbuds so most everyone can find one to fit. The only reason I didn't give it 5 stars is because the on/off button is really tiny. Other than that, save your money & buy this fantastic product!
