EPOS GSP 600 Review


The EPOS│SENNHEISER GSP 600 is a premium closed acoustic gaming headset that’s been built on EPOS’ passion for audio. SENNHEISER boldly claim to deliver on competitive edge performance, high audio fidelity and precise accuracy, but can the GSP 600 deliver on this promise? and is it the right choice over the GSP 500? Let’s find out!

If you haven’t already, I would suggest you take the time to read over our review of the GSP 500. Otherwise, keep reading our EPOS│SENNHEISER GSP 600 review to find out which headset is right for you.


In 2019, Sennheiser Communications unveiled a new division dedicated to translating design, technology, and performance into high-end audio and video devices for both gaming and enterprise solutions called EPOS. The newly formed EPOS brand builds on a foundation of more than 115 years of experience in audio and promises to pioneer the future of audio technology.

Design & Comfort

The GSP 600, as with all EPOS│SENNHEISER products, feels and looks premium. The headset itself is solidly built and while on the larger side when compared to other brands, the design is not completely over the top gamer – something I really appreciate. There are plenty of aspects that still look aggressive, but the GSP 600 strongly represents quality over RGB flash.

For my head shape, the GSP 600 sit fairly tight and low over my ears. I found myself readjusting on several occasions trying to find a comfortable sweet spot. This is where the adjustable tension certainly comes into play. This handy feature adjusts the contact pressure (clamping force) of the headset via a slider on the top of the headband. Once I found the right angle and settled in with the plush leatherette and suede-like material ear cups, it made for comfortable, extended gaming sessions.

The GSP 600 features the same boom mic design that’s found on other headsets in the GSP range. An omission I would love to see for future models would be the ability to push or tap to mute the microphone. While the mic can be muted by lifting it to its vertical position, I personally feel a button just feels a little more practical.

The right ear cup hosts a notched wheel that controls volume for quick adjustments that’s especially useful when console gaming.

The GSP 600 comes packaged with a 2.5 m GSA 505 PC Cable and 1.5m GSA 506 Console Cable. This means they can be used with PC, Mac, PS4, Xbox One & Nintendo Switch or any device with a 3.5 mm jack input, making them a great pick if you run multiple and varied battle stations at home.

Audio Performance

Driving the GSP 600 during my testing was the EPOS│SENNHEISER GSX 300, an external USB sound card designed to level up onboard audio, which you can check out our full review above!

As we have come to expect from EPOS│SENNHEISER, the sound quality that comes from the GSP 600 is excellent. While they do lack that really big open sound stage you get from the GSP 500, the GSP 600 delivers on lower frequencies. But unlike the subwoofer in the 97 Honda next to you at the traffic lights, the bass is satisfyingly low and detailed all while managing not to wash out the hi-range or destroying mid-range clarity.

The GSP 600 covers an impressive frequency response range from 10–30,000 Hz, especially when comparing to the Razer BlackShark V2 Pro (12–28,000 kHz) or the HyperX Cloud Flight S Wireless (10–20,000kHz). The broad response range coupled with German-engineered drivers the GSP 600 is able to deliver a listening experience that needs to be heard to be appreciated.

Engineered to deliver competitive edge-boosting performance, the GSP 600 delivers high audio fidelity and exceptional realism with precise accuracy.


With the GSP 600 tethered securely to the GSX 300, I had my sights set on gaming. First, after a fresh 50 gig update, Call of Duty Warzone. This is where the headset really came into its own; Bullets whizz by with clarity, grenades crack like thunder, and gunshots rattle your teeth — The overall quality of the audio really elevates the battle royal environment.

Now onto trusting the GSP 600 with my Overwatch competitive rank. While it certainly didn’t help my SR climb, I mostly blame my complete lack of game sense for that, they did do a fantastic job of making sure I didn’t miss enemy voice lines or footsteps giving me even me a fighting chance of dodging the enemies Nano’d Genji blade.

D.Va’s mech makes a satisfying thud as it crashes down to earth and Widow’s sniper rounds sound brilliant as they zip by completely missing you – because Open Queue is basically just a place for Gold DPS PLAYERS TO PRACTICE THEIR SNIPING! Moving on…

Putting the GSP 600 through their gaming paces really highlighted for me how well EPOS│SENNHEISER can put together a headset. Their years of experience in making high-end audio devices really shine through to deliver a very well rounded headset.

Microphone Performance

The GSP 600 also features an advanced noise-cancelling broadcast-quality microphone boasting a frequency response from 10–18,000 Hz and a sensitivity rating of -47 dBV/PA.

I did find I needed to have the mic in nice and tight to ensure some of my more softly spoken shot calls were heard by teammates. Thankfully, the microphone’s flexible lift-to-mute boom arm allows for easy adjustment to ensure you can find the optimal position for voice pick-up. Noise-canceling works well and with help from the uni-directional pickup pattern, even managed to filter out more of my keyboard noises than some of my previous headset mics. Overall, the microphone does a solid job. I probably wouldn’t use it to record a podcast, but for gaming, vocals come through clear and strong.

GSP 600 VS GSP 500

Fuller, richer and deeper. These are the words that popped into my head when first directly comparing the GSP 600 to its sister headset the GSP 500. And, well, that’s to be expected as the GSP 600 are not open back like the GSP 500.

Design-wise the GSP 600 is almost identical in every way to the GSP 500 but with a few small but notable changes. Namely, the open vs closed back acoustics of the earcups. In addition, the GSP 600 metallic red accents on the speaker cups are now a larger slightly more aggressive triangle shape. The ear cups have forgone the fabric wrapped ear cushions in place of plush suede-like material with a soft leatherette around the sides.

The enclosed ear cups of the GSP 600 give you much more impactful bass when comparing to the GSP 500 all while blocking out a considerable amount of noise pollution. You do forgo the open-back acoustic nature and wide soundstage to some extent. But I feel the GSP 600 tumps by blocking the outside world that pulls you into a more engrossing gaming experience.

The GSP 600 also have a higher sound pressure level, when comparing directly to the GSP 500, 112 vs 107 dB SPL @ 1 kHz, 1V RMS. This was fairly evident when gaming at higher volumes where, with the right noises, I could feel the change of pressure in my ears.

Both headsets perform more than adequately in a gaming environment. For me, the GSP 600 do manage to achieve a higher immersion level during gaming by delivering those deeper tones with much more punch. Also, the way the closed-back cups manage to block out most ambient noise meant I could really focus on the gaming action. That being said there were one or two occasions where the GSP 600 maybe did too good of a job blocking out the outside world… I did miss my wife calling out for help to change out our son’s nappy, still not sure if that’s a pro or a con…

If you want a no distractions gaming experience then the EPOS│SENNHEISER GSP 600 definitely wins out this battle.

The EPOS│SENNHEISER GSP 600 is a terrific choice for someone looking for a deeply immersive gaming experience. The microphone is clear, clean and performs well in the heat of battle. While they are on the larger side, the adjustability means even the most mellon-headed player should be able to find a comfortable wearing position.
