The GSP 300 is Sennheiser’s headset for gamers who want a versatile product that’s suitable for music, gaming and chat. It combines a highly respectable build with solid audio quality, but remains lightweight and comfortable over long periods of time. While the lack of any form of virtual surround sound may put off some buyers, those wanting simplicity will find that the GSP 300 offers a thoroughly rounded performance at a very reasonable price.

The Sennheiser GSP 300’s are considered to be a compact pair of cans with a relatively small footprint when the mic isn’t in use for gaming purposes. The review unit I was sent over is a two-toned blue and gray for coloring. The blue is more for accents as the majority of the headphones, which are plastic, are dark gray in color. This really looks nice compared to a single solid color as you get with so many headphones. The difference in the Sennheiser being plastic compared to a lot of other headphones is that with Sennheiser you’re getting quality.

While I’ve never personally reviewed a pair of Sennheiser headphones(yes, this is my first pair to review actually), I’ve used several in the past for brief periods of time but I could tell instantly with each pair that they were of great build quality. This is especially important for gaming headphones where to me it seems you’re taking them on and off a bit more than normal for various reasons.

The headband across the top is also plastic, but lined with padded blue cloth on the bottom side of it which is the side that actually sits on your head. It’s very comfortable feeling even after wearing them for several hours as I do tend to play Destiny 2 for 8+ hours at a time. I never got a feeling of itchiness or anything similar which is usually the case with a lot of headphones that have cloth on the headband.

The GSP 300’s also clamp to your head tightly, but not in excess to a point where they are pushing against your ears and into your head. It keeps them in place and for me, this is extremely important as I’ll just say I really get into my video games at times, so I do a bit of excessive moving unlike most.

The ear cups themselves are oval in shape, allowing for my ears to nestle comfortably inside. The sizing is good, though the material choice may not to be everyone’s taste. It’s a leatherette finish; a popular choice among headset manufacturers. It feels pleasing against the head, but it does have the tendency to get a little hot and sweaty during long gaming sessions. If Sennheiser had provided an additional set of fabric ear cups, it would have added another string to the GSP 300’s bow.

The left side of the headset houses the large boom microphone. Unfortunately it’s non-detachable, which does limit its versatility, but it’s not a huge deal. Move across to the right-hand side, and you’ll discover the large volume wheel. It’s dead easy to use, and allows for pinpoint control. I can’t stress enough how annoying tiny headset dials and knobs can be, so it’s a really refreshing change to find such an elegant and practical solution here.

Connecting the headset is easy. PC users will likely wish to utilize both of the 3.5mm jacks, while console users will want to use the supplied adapter to create a single 4-pole 3.5mm jack. This then connects directly into the controller on your Xbox One or PlayStation 4. Console users may find that the non-removable 2m cable is a little too long, however.

Sound Quality

Sound quality can be a little hit and miss in this price range, but thankfully the Sennheiser GSP 300’s deliver in all scenarios. After listening to Spotify for roughly 10 hours, I’ve been impressed with nearly everything I’ve heard. There’s plenty of detail in vocals, and a smooth richness to the overall sound. The low end isn’t the strongest around, but an overpowering bass isn’t something that I’m personally looking for in my audio.

If I were to criticize, it would be that that higher notes are not controlled as well as I’d like, and can come across a tad sharp. The GSP 300 also doesn’t compare particularly well to Sennheiser’s own Momentum headphones, which can be found for a similar price. I can’t really complain though, as I’m sure that most will be rather pleased with the sound here, with a stronger performance than the more expensive Logitech G433.

Gaming is also an area of strength for the GSP. While the 300 lacks any form of surround audio smarts, the clarity and warmth of the sound make it highly versatile, and suitable for most genres. For my testing and as I stated earlier on, I played a ton of hours of Destiny 2 wearing these while in a party chat with friends and even a few hours of just playing without being in a party chat so I could hear just game sounds.

The audio was full of punch, with plenty of heft behind every explosion of a grenade, pop of a super or just every gunshot in general. While my awareness could well have benefited from an implementation of 7.1 surround, the sound stage felt wide enough, and I never felt at a disadvantage. Overall game play sounds were truly worth listening to on the GSP 300’s and something I’d recommend.

As for the party chat conversations and quality of those conversations, I’d say the same thing. Quality was crystal clear and there were no issues with sounds breaking up when I was talking or hearing others in my party when they spoke. Definitely something that is very important when playing a game such as Destiny 2 when you require a lot of communication between teammates as this is where I spend most of my time wearing headphones or earbuds or whatever.

From what everyone was telling me, my voice sounded very clear as well via the GSP 300’s. I verified this by having my fiancee wear them for a raid we did in Destiny 2 that took us just under 2 hours. I never once had an issue hearing her and the quality was beyond excellent.

Another important thing to mention with regards to the Sennheiser GSP 300’s is that they do come with noise cancellation. This is very important to most anyone when using these to listen to music. We simply want to hear our music and nothing else around us and the GSP 300’s allow us to do just that and to do it very well.

Final Thoughts

Sennheiser is known to be a bit more on the expensive side when it comes to their products, but there’s a reason for that. They simply work and they work well. With that said, the GSP 300’s are currently selling for $85.00 which is one hell of a great bargain for the quality of product you get plus the quality of sound you get for that low of a price. Very unusual to have a sub $100 pair of headphones produce such good quality all the way around.
