I've been using this headset (although mine doesn't have the call answer button like this version does) for a few years now. It's the first headset I've ever used that was comfortable and had great sound quality in both directions, and I've used it with 3 different phones over the years all with the same results. I hear people perfectly and I've never had a single comment much less a complaint about the sound quality from other people. It comes with two different size gels for your ear, and a spare of each so you're totally set. Depending on the shape of your ear you may prefer one or the other of the ear gels.This headset is so comfortable I can wear it on my ear for hours at a time without it bothering me, and it stays snugly against my cheek and doesn't flop around in the slightest. I don't know why it has gotten some bad reviews on this site, on other sites it averages at least 4 stars with many, many reviews. Bottom line, I'd gladly pay 2 or 3 times what Amazon is charging for this headset, especially now that it has an answer call/end button on it.
