Fake 7.1 is something like you got installed software in it and it got only one repro on every side of headphones (like prozajik said, + look at picture what he posted with headphones - he posted how real 7.1 headphones looks like), what is trying to act like real 7.1 but it is a little bit different. Real 7.1 in headphones are made with few repros for example 4, 5 repros on each side and it is simulating real 7.1 sound. If you went for razer, and you can still give this razer back, go exchange it for Razer Tiamat 7.1, or HyperX Coud II or if you can pay more buy this one SENNHEISER PC 363D. These sennheiser comes with USB soundcard so you will get 99% close to true 7.1, i don't know if it's worth for this price, but w/e. You can even buy some Logitechs, but what i heard, they aren't really comfortable.
I don't know a lot about other headphones, but i own HyperX Cloud II, these got 7.1 99% similar to repros placed all over the room in 7.1 cuz of the new kingston profile. If you wear these headphones and playing with 7.1 or watching movie it really feels like the sound is no longer coming out from headset so close to your head like a lot of 7.1's but from much larger audio sources in the distance. I had Razer Kraken 7.1 (not chorma), and it is not huge, but significant difference. They got remote for turning on 7.1 and turning off, because they wanted to make stereo sound (primary one) so you can use them without mic out in the streets - they don't look like gaming headphones, or you can connect it thru remote via usb to PC/laptop and turn on your 7.1 in headset.
Just one thing i don't like on these HyperX is that clear audio separation between all types of elements becomes a little bit more difficult when you turn on 7.1. Example: footsteps became less detailed because everything is pushed back, BUT you get an extra sense of where those footsteps came from. So it is - and + too. Long range setting for ears, Earcups are exchangeable, 2 types of earcups, great feeling leather + extra padding (real leather one and large and comfortable velvet ear pads to cushion your ears while gaming). This small but very important feature is usually found on more expensive headphones. One minus i don't like at all is MIC, it is only good for communication, because it has noise-cancelling microphone, but for streaming/videos is better to buy normal MIC. This one is decent.
I was researching about this headphones and u can get basically headphones for 100 bucks, worth 200-250 bucks.
