I really wanted this headset to work out because it is being sold at such a good price relative to most others. Well, it prooved to me that you often get what you pay for. Let's consider the following in why I am returning this headset: pairing, sound quality, ease of use, and comfort.Pairing - this really belongs with ease of use, but it is really your first experience with a headset other than charging it. It was hard to figure out if I was holding the multifunction button down long enough to get the headset in paring mode. After 4 attempts, I got it right. My LG VX-9800(see my review)was able to pair with it easily after this. However, it shouldn't take 4 attempts just to get a headset into pairing mode.Sound Quality - this is actually the area where the headset does the best in my opinion. With the speaker resting inside my ear, I didn't have to have the volume turned all the way up in order to hear the people I called. My wife reported that she could hear me clearly with one exception. When I had the AC fan speed in my car set to 3 (out of 4), she said that it sounded like I was in a wind tunnel. Kicking the AC down to 2 fixed the problem, but once we hit the Texas summer that could be a problem.Ease of Use - I think that Plantronics' attempt to make this headset easy to use backfired. I would go to turn on the headset, but I would always have to check my phone to see if it was connected. Initiating voice commands also required multiple attempts before I would hear the familiar "Please say a command" from my phone. However, what really drove me nuts was trying to turn it off. I would hold down the multifunction button for what I thought was the amount of time specified in the instructions, but I kept getting "Please say a command". Compare this to the Motorola HS850(see my review) where on/off is controlled by the folding boom while the multifunction button simply handles pairing, voice commands, and call connecting. I consider my self to have technology savvy and able to fight through things to make them work, but this headset *still* frustrated me. If you like things to work simply, this headset isn't for you.Comfort - I was willing to put up with the flaky operation of the headset because of the cost; however, I realized after two days that I was not going to be able to stand to wear it for any extended period of time. The speaker pipes its volume into a rather hard earpiece that fits inside your ear. It is not removable, and try as I might to adjust it, I could not find a comfortable position. The ear hook is also fairly rigid. These two things combined made for an unpleasant comfort experience.I have to consider this headset to be a failure. On the box, it touts "Comfort" and "Ease of Use". As you can see from my results, it doesn't deliver on either of these. It's a shame because it does deliver good sound quality at a reasonable price. Unless you have the ear it was modeled after, though, I would not buy it.
