A:AnswerSound & mic both are pretty good. Although not featuring background audio cancellation but does the job. I didn't have any issues so far. One good thing I noticed is, you can hear your own voice in the headset so no more shouting.. ;)
A:AnswerOther than running Spotify or Pandora in the background while you play, no. There's no 3.5mm port on this, and it's not Bluetooth, so you can't listen to music on your phone. The volume is very low, however, and the quality isn't the best. If you're into music I would buy something else.
A:AnswerYou can use Dolby Atmos (Paid) Or Windows Sonic (Free) settings for your headset for surround sound experience.
Personally, I like Dolby Atmos better compared to Windows version.
A:AnswerNo you can't it is completely wireless besides the charging cable that is it. I would not recommend these for gaming at all this headset is terrible keeps cutting out and making game audio sound terrible returning mine for the HyperX Cloud 2.
