My wife and I bought these as replacements for our bluetooths (blueteeth?), because it seemed like neither of them ever provided a good connection. I read the reviews here and these seemed decent, but I was skeptical due to the price. We ordered them and figured if they didn't work well, we wouldn't be out much. We were very pleasantly surprised. It is actually clearer than NOT using a headset. My wife drives our son home every day and we usually talk on her way home. When she talked directly into her cell, often she had to hang up if he was crying or screaming because I couldn't hear her. With the noise cancellation, I can still hear him but it sounds like he's further away and even full-on tantrum I can still hear her clearly. The downsides? It's not incredibly comfortable, but it's OK for an hour or so and it fits securely. Plus it only takes a second or two to put it on your ear anyway if you don't care to keep it in all the time. It also doesn't have the features of a bluetooth, like a button to make or answer calls, and the actual headset doesn't make any sound when you receive a call. But seriously, what do you want at this price? Excellent product - very highly recommended.
