I'm sorry to give such a terrible review but I bought these today and I'm finding the sound quality is really awful. I'm not sure why anyone is saying it's good or even passable. I have no effects on and it sounds like everything is playing from a tin can. Perhaps if you included an equalizer in the software it would help. I see no difference other than stereo widening on the 7.1. They're comfortable and all, but the sound is sort of the whole point. Isn't it? They go back first thing tomorrow...

I've had these for almost a month, and while they are a good buy, Plantronics has not released a driver/software for Windows 10. If you're on 8/8.1, great, I'd recommend them, but if you are on 10 (and update your OS frequently), I'd recommend looking elsewhere. Plantronics, and other manufacturers, have had over a year to get drivers and software ready for the launch of Windows 10, but it's obvious Plantronics will get to it when they feel like it. Sure, there is a workaround, but why should I have to follow a workaround that was provided by a customer of theirs! It's not even a workaround by the company! Ridiculous.
