Summary: I like the fit, and the volume up and down and mute and phone built in the set. I have less reaching to do. They make my job easier and I no longer have to strain to hear one customer and the next is way to loud I have more control over the volume of the call. I am very happy with the Plantronics Audio 628 Stereo USB Headset!
Summary: I use Linux, and sadly Plantronics doesn't support Linux, so the headset doesn't work completely as advertised. Linux buyer beware, the in-line controls don't function unless you do a little fiddling in your audio settings.
Excerpt: I bought these from B&H to upgrade my older Plantronics .Audio 476, that I have been using primarily with Dragon NaturallySpeaking for a couple of years. Although it worked fine, for the most part, I wanted a more stable microphone position, which is very important when using Dragon.
Pros: Comfortable, Good audio quality, Quality Microphone
Summary: Never used Plantronics before and heard good things about them so thought I would try this. Absolutely did not work. I bought this for use with my Playstation 3. Plugged it in and the sound was fine but the mic was not detected. I thought ok I could always use it for my pc. After plugging it into my PC and it installed the drivers the mic did not work. I am returning this tomorrow and I will be finding a different product. I would recommend you find something else...
