Summary: I bought 3 of this , it look like had everything we need , noise cancelation, comfortable... but 1 didn't work from the start and the other 2 after a month stop working properly there was not noise cancelation and now are useless for us.
Summary: Newegg is absurd with their return policy. Make certain what you're buying is what you really want.
Pros: Are loud when you turn them up; microphone is good quality.
Cons: Uncomfortable and cheap - this is not what I expected from Plantronics, and I have trusted their stuff for a very long time. This one is junk, and believe me, I would call them worse if the censors wouldn't take my comments out. Save your money - these will just end up in the trash. Don't say you weren't warned!
Summary: Bought from Best Buy will be returning them tomorrow and buying a Fatal1ty off Newegg.
Pros: Great bass and decent overall sound quality for the price
Cons: I feel as if I was wearing clothes pins on my ears if I wore them longer than a thirty minutes. The maximum volume on the headsets is low for my liking only about half what my ten dollar Logitech that's 5 years old (which I am wearing now and feels like silk) Oh and Realtek HD audio manager has trouble finding this headset when you plug it in AND will NOT cancel any background noise.
Cons: Breaks after 2 weeks. I ordered this May of last year and within 2 weeks the sound in both ears went out, I RMA'd it, finally got a new one a month later, and it broke with the same problem within about 2 months.
Cons: Everything. Mic is low-quality, everything is low-quality. The left audio speaker blew out within 1 week and only either nothing or static came out of it. The mic didn't work either after about 3 weeks.
Summary: I bought this item to use on Skype and it is a complete waste of money. The earphones are so badly insulated that sound can be heard by anyone within a 4 foot radius. The microphone quality is so poor that I have to unplug it and use the laptop microphone just to be understood. I would send it back but it's not worth the postage!
