When I visited a local retailer, they told me this was the model of bluetooth headset that never gets returned by customers. On that basis, I decided to give it a try. And now, having used it for a week, I can see why it's rarely returned.Sound quality is just fine for highway driving, even with the volume a couple of notches lower than the maximum setting.Also, I have large, sticky-outy ears, and even on me, the headset is so light and fits so well that I can leave it on there all day. I hardly notice it's there. It stays on even if I swivel my head quickly when changing lanes.I won't be returning mine either, and would have no problem recommending this same model to others.
