Most of the time 7.1 speakers are a gimmick and can distort the sound, however if you really want it, the HyperX Cloud II are the best budget headsets out at the moment, at around $85 USD.
If you're willing to spend the money though, the Sennheier G4me Zeros have amazing sound quality and some of the best directional noise in a noise canceling headset. Noise cancelling itself is great, and the mic is high quality too.
One of the better high end gaming headsets. (Comes with adapters for phone and console too)
