Was looking for a headset on Amazon with both USB and 3.5mm compatibility, and miraculously stumbled upon this headset (I think it was like a recommended from another headset I happened to be on). Anyways, if you come across this headset as well looking for both compatibility options, you came to the right place. Sound is good, although not like crystal clear or anything. Gotta keep in mind this isn't top tier headset. But for what you get, it's pretty freaking good. Plus you can play with the sound settings that you like (I like my bass to be slightly louder and was able to accomplish this). Mic quality is good according to my friends and when I hear myself talk it's not bad at all. Headset is a little tight for me and the ear cups just fit my ears, so my ears hurt a little bit after wearing for an extended time, but no crazy complaints.So reason for the 4 stars (I would have rated 4.5) is because the software that you need to download to play with the sound settings is not as straight forward to do. I tried downloading the "Old" version because the box my headset came in looked to be the old style, but the download didn't work and I kept getting this annoying error. Ended up uninstalling and wiping from my computer. I tried the "New" version, and for some reason, this one worked, although I get a blank icon which is weird to me, but not an issue really.So other than the weird software download, I really like this headset and I think the TRUE multiple compatibility with USB AND 3.5mm beats out a lot of the other headsets that have just 3.5mm. For the price point, I think you really are getting a good bang for your buck.
