Reddit mentions of EPOS I Sennheiser GSP 600 – Wired Closed Acoustic Gaming Headset, Noise-Cancelling Microphone, Adjustable Headband with Customizable Contact Pressure, Volume Control, for PC + Mac + Xbox + PS4, Pro

The black & copper pair don't look as cheap as the black & blue pair but I'm surprised Audeze is branching into the gaming market. I figured they were too far into the boutique market but nothing wrong with expanding the product stack. I see a couple big issues with these though:

1. The gaming headphone market is already ridiculously crowded.
   
2. Every company seems to have this "new & revolutionary 3D surround sound emulation" technology but they all have 2 drivers like the rest. Between Sennheiser's new GSP 600 with "7.1 surround sound" & Steel Series' new Arctis Pro + GameDac that have both released in the past few months Audeze doesn't exactly have a fresh take. This is ignoring the other options from Logitech, Astro Gaming, Turtle Beach, Triton, etc. that all claim to do the same thing. On top of those you have built-in surround sound in Windows 10 with Windows Sonic as well as a Dolby Atmos plugin as standalones that work with any headphone.
   
3. Even if they do have outstanding imaging with their 3D emulation they're still closed back so the soundstage could potentially be an issue.
   
4. Bluetooth is great for mobile, but it's a hard sell for a desktop environment at least for me. I'd rather be wired, or have a dedicated amp for wireless like Astro A50s.
   
   Head tracking is a meh worthy gimmick too. Monitor manufacturers have been pushing eye tracking the past year or so which is more compelling because I don't move my head drastically enough during a session & certainly not enough to want to see data about it.
   
   And finally, at $400 retail they're more expensive than just about everyone else. I don't see these doing all that well tbh. Cynical take but I feel my reasoning is justified.

Bought these for my kids Sennheiser GSP 600 Professional Gaming Headset

Overall, pretty good. Comfortable, FAR above average fidelity for a gaming headset, mic is probably one of the best mics I've ever used that is part of a gaming headset. Again, my kids like them.

I personally don't like gaming headsets.

My personal gaming rig does not use "gaming" headsets.

I use regular low end audiophile headphones paired with a mixer + mic.

• beyerdynamic dt990 pro I prefer the open back headphones for the wider soundstage. VERY comfortable for long play sessions.
  
  
• FiiO E17K (E17) Alpen 2 Portable Headphone Amplifier USB DAC
  
  
• Yamaha MG10XU 10 Channel Mixer
  
  Again this is solely for gaming and not listening to music.
  
  For music it depends what I'm listening to but I have two primary set of cans.
  
  
• Sennheiser HD 800 S Reference Headphone
  
  
• Beyerdynamic T1 2nd Generation
  
  This is my primary amp for music:
  
  
• Sony Signature Series Audio Component Amplifier
  
  I caught the "headphone" bug so I've got tons of mid range cans too e.g. Sennheiser HD660, HD700, a couple of tube amps etc.
  
  Hope it helps.
  
  
  
  

Sennheiser GSP 600
I've had these for about 3 weeks. I was tired of the plastic parts that connected the earphone to the head band breaking. My XO Sevens just did that and their not even a year old. These have aluminum connectors. And the surround sound is the best I've ever had.

They don't make the PC 363D anymore, they have the newer PC 373D which I'd definitely check out if I were you. You can get them for $96 euro on Amazon or on sale for $135 euro (normally $249.99) from Sennheiser. You should also check out the noise-canceling GSP 600 which is on sale on Amazon for $178 (normally $249.99) and the open-back GSP 500 which is currently $135 euros from Sennheiser or $144 on sale on Amazon (normally $225.) Any of those are good deals. You can see all their gaming headsets here.

This is my rig:

I also bought the same rig for my fiance. It's the best i've ever tried, and i've tried ALOT of headsets. This is the only surround sound i've ever heard that's worth using.
