No, it is not. However, in my opinion, this is not a problem, as other headsets that promise 7.1 are also only stereo headsets that create the effect of surround using software. I play a variety of games including CS:GO, Overwatch, PUBG and played each with this headset and the Razer Kraken 7.1 and have to say that the difference is minimal, my gaming performance didn't get any worse and the Sennheiser has the much better sound (nicer highs and mids as well as better mic.), the Razer or other brands deliver a richer bass, but this is just a trick in the industry to make poor highs and mids less audible (see Beats by Dre).
