The Sennheiser GSP 600 firmly grabs your head with nigh sound-proof ear cups and delivers beautifully balanced stereo sound quality.

Representing the high-end of Sennheiser’s dedicating gaming line, the GSP 600 is aimed at (or inspired by) the demands of eSports, which generally means a streamlined design centered on audio and build quality with an effective but minimalist feature set.
The GSP 600 connects via a standard 3.5mm speaker and mic connectors and includes an additional, single 3.5mm adaptor. A large volume dial occupies the left ear cup, and the microphone auto-mutes when raised, making a tactile ‘click’ when it switches off.

GSP 600 audio quality
The GSP 600 definitely delivers a very well-balanced and outstanding ‘out of box’ audio experience. Without any EQ adjustments, it provides a virtually perfect balance of strong bass with excellent mid and high-range clarity, perfect for gaming, music, and movies.
Microphone quality was also quite good across a range of games. It got its biggest workout in Overwatch and some video conference applications (for business), for which it worked flawlessly. (It’s worth noting, however, that I don’t typically perform anything close to an exhaustive analysis of microphone performance.)
GSP 600 comfort and design

Audio quality is further enhanced by its heavily sound-proofed ear cups, which combine thick, leatherette-lined memory foam liners and an almost skull-crushing grip on your head to deliver distraction-free audio.
Thankfully, the GSP 600 headband provides adjustable length and some innovative “expanders” (for lack of any formal description) that let you widen them a bit to counteract some of the head-smashing.
Regardless, the GSP 600 can get a bit tight and warm after extended (more than one hour) of play time—especially during a hot summer.
The GSP 600 is largely plastic but still solid, with a very durable and flexible headband. It’s clearly built to withstand punishment.
Overall 8.5/10

The Sennheiser GSP 600 delivers a streamlined and effective design and a very well-balanced audio experience. It might feel a bit too tight after more than an hour of use.
More importantly, it’s $250 price tag can be hard to swallow. The GSP is well worth checking out, but the premium price can make it hard to justify against an ocean of less expensive headsets that may be “good enough” for non-pro gamers.
