Bests & Worsts Reviews from Amazon

These are very comfortable. I have a very large head and wear glasses and these have a suspension band that makes them very comfortable in almost all situations. I didn't realize that they notch and lock down at first, but once I figured that out, they were a perfect fit. Mic quality is excellent. I've used these with Vidyo, WebEx, Skype, and GlobalMeet so far. In each instance voices in the headphones sound great and my voice sounds fantastic to others. The mute function is very well done and is right on the microphone with a solid quick pronounced button. These headphones detect when you're trying to talk while you're muted and they alert you that no one can hear you speaking. You can change the setting to be audible, display a notification, both, or none. Overall Audio quality is also great. Definitely Plantronics voice audio quality here. I can listen to music in full fidelity. When you communicate with the mic, the headphone switches profiles, even with the adapter and there is a drop in music quality. The drop is notifiable, but it's still usable for gaming. The bass is rich, the mids are pronounced and well defined, and the highs are great. The headphones are doing some fancy realtime DSP when listening to music and the quality is very well pronounced for professionally office headphones. Range is also decent. These go much further than my BackBeat Pro's and I can use them all over my 950 sq ft work space with no problems. If I do get too far, the quality drops for the first few words, then switches to a higher band and picks right back up. This is a little annoying, but it handles it well. As long as you are within 50ft, you shouldn't run into any issues. Noise cancelling is very light. It's not overbearing, but it's a very subtle effect that is hard to notice. I get motion sickness from Bose noise cancelling, but these don't bother me at all. The build quality feels good. They don't feel cheap like other headsets can feel. The dock is solid and well built. The headphones slip easily right in. I've used these enough now that I can comment on the battery life. For heavy voice and music I get 12-14 hours before they die. You get an audible alert an hour before they day, and the software estimate for battery life is very accurate. Once you get these, make sure you update the firmware. The firmware on the USB accessory and the headset both increase range and improve performance and audio quality. There is a slight quality drop when using pure bluetooth vs the dongle. It won't be noticeable to most people however. Let me know if you have questions about the headphones or software!
