Bottom Line

Despite being Sennheiser’s very first crack at making a wireless gaming headset, the GSP 670 offers a level of audio quality like no other in its price range. If you’ve got $350 to spend on a gaming headset and you want the best sounding wireless device on the market, this is an easy pick. Just make sure you’re okay with how it handles its other features.

The GSP 670 headset is the very first wireless gaming headset made by Sennheiser, which made it difficult for fans to properly temper their expectations prior to the release.

On the one hand, it’s Sennheiser! What more could you want? This company has made some of the all-time best headphones on the market and their audiophile-level sound profiling is something many other manufacturers aspire to.

On the other hand, they had literally never made a wireless gaming headset before, which for many was a cause for concern.

So, was the enthusiasm of the fans well-founded, or did the naysayers have a point?

Let’s find out.

    Design

    Sennheiser GSP 670

    Sennheiser headsets have always walked a fine line between the aggressively gamey aesthetic replete with angular designs and RGB lighting and the more inconspicuous design quite admirably, but we feel that they have stepped up their game even further with the release of the GSP 670. 

    This headset saw Sennheiser finally give up on the red and black color scheme of gaming headsets and go in a more refined shades-of-black direction. The highly angular, bulky, and almost sci-fi exterior still helps distinguish it as an unequivocally gaming headset. The GSP 670 demands your admiration, but not in an attention-grabbing, or even downright distracting way that many RGB-lit headsets accomplish this.

    It’s not a design that will appeal to everyone, but we must commend Sennheiser on accomplishing everything they aspired toward with this design principle. Needless to say, the headset also has a very premium feel to it.

    Of course, if you’re a fan of flashy accessories, you can still breathe some life into the GSP 670 by swapping the removable side plates. The selection of side plates isn’t too varied, but the customizability option is present.

    The large earcups also feel like they have an appropriate amount of gadgets built into them considering the size. The left earcup features the microphone and charging port, but it also has a slide switch that serves multiple purposes, while the right earcup comes with a large volume wheel, smart button, and a smaller chat mix wheel.

    All in all, the GSP 670 sports an aesthetic that’s hard to dislike – the angular, futuristic shape combined with the sleek and stylish color scheme simply gives off an impression that feels distinctly gaming but not distracting.

    Comfort

    We said that you get a premium feeling when you hold this headset and the weight is undoubtedly part of the reason for this. This device weighs in at just under 400 grams, which we can by no means categorize as lightweight.

    However, it’s still a headset that we could wear for hours on end without any issues, so don’t let the weight concern you. The folk at Sennheiser have gone to great lengths to ensure that wearing the GSP 670 is an absolute joy. This should be evident just by glancing the generously thick, soft padding both on the headband and the earcups. The ear cushions, in particular, as very plush but the material still manages to combat ear sweating while still allowing for some truly impressive passive noise cancellation.

    The GSP 670 combats comfort concerns even further by not only offering dual-axis adjustability on the earcups to help fit all heads, but also a slider on the headband that can be used to adjust the clamping force. This last feature is one we don’t see very often in gaming headsets but it’s certainly appreciated and guaranteed to let you find the perfect zone of comfort.

    We’ve expected no less from a headset at this price, but the GSP 670 is a device that you’ll forget you’re even wearing.

    Features

    Sennheiser GSP 670 Headset Review

    Now this being a Sennheiser product means that you shouldn’t expect any flashy accessories to help persuade you into buying it. Out of the box, you just get the headset, the USB dongle and the charging cable, which speakers volumes about the level of confidence Sennheiser has in this product. This confidence is neither unwarranted nor unearned, but it does place a higher emphasis on the core features.

    And speaking of the core features, the most important one by far is the USB dongle. This is what you’ll be using to connect the headset to any device 99% of the time. There is also a Bluetooth option and you can conveniently enter Bluetooth pairing mode by holding the side switch on the earcup for a couple of seconds, but Bluetooth connectivity is strictly an afterthought with the GSP 670. The wireless connection always takes priority and it’s the only mode that allows you to use the other features which we’ll mention in a little bit.

    Now what’s most impressive about this dongle is that it truly offers that low-latency wireless experience. You shouldn’t settle for anything else at this price range, but considering that this was Sennheiser’s first foray into the realm of wireless gaming headsets we had to see it first to believe it. A wired connection will always be superior to wireless ones, there’s simply no getting around this, but as far as wireless headsets go, his one accepts no compromises in terms of latency.

    Sennheiser GSP 670 Bluetooth

    It’s just a shame that the same cannot be said about its signal range. The headset works brilliantly when you’re sitting in front of your computer and gaming away, but if you like to wander around the house in-between matches with the headset on and some music playing in the background, you’ll find the GSP 670 rather underwhelming for its price. Whereas competing headsets let you explore every nook and cranny in your home without compromising the wireless signal, a single wall can often prove to be a hurdle too large for the GSP 670 to overcome.

    In addition to the PC, you can use the dongle to connect this headset to your PS4, however, you won’t get access to any additional feature this way, including the 7.1 virtual surround. So when we couple this with the limited Bluetooth support mentioned earlier, it becomes clear that the GSP 670 is not a headset made with versatility in mind.

    Aside from the dongle, we have to mention the Sennheiser Gaming Suite software. Once you run this software, you can program the smart button on the earcup to switch between the 2.0 and 7.1 modes or to switch between the EQ options. The software includes several presets and also allows you to customize the EQ in any way you like. This goes for both playback and the microphone.

    All in all, it’s a very functional piece of software, but it doesn’t offer as many features as some of Sennheiser’s competitors that are more seasoned in the gaming scene do. Granted, it has all the essentials, but who doesn’t like having some additional bells and whistles?

    Battery

    There’s also nothing particularly noteworthy about the battery. 20 hours of battery life isn’t bad, but considering that this is a $350 headset, you’d think it might offer more. Especially since the battery is estimated at only 16 hours when using the low latency mode, which of course you’ll want to use all the time if you’re gaming.

    It does come with some cool features. For example, you can use this headset while it is being charged, which, surprisingly, isn’t something all headsets support. There’s also a turbocharge mode that lets you charge the headset for only 7 minutes to get 2 full hours of use out of it. And if you swipe the slide switch once you’ll get a voice notification telling you at what percentage the battery life stands.

    These are all pretty nifty quality of life features, but they would’ve been even better if the battery life was a tad more in line with the competition in the first place.

    Microphone

    Sennheiser GSP 670 Headset

    Now where the GSP 670 makes no compromises is with the microphone. This swiveling microphone offers a broadcasting level of quality. It can’t compete with wired microphones in this price range, but then again, it’s not like we were ever expecting it to. What’s important is that it easily beats the wireless competition with a clean and crisp sound that’s simply magnificent.

    And you can further customize the microphone pickup in the Sennheiser Gaming Suite. In addition to the regular mode, there are also Warm and Clear modes. We can’t say that we’ve felt any difference when switching to these modes, but the default sound is so good that you won’t feel the need to switch in the first place. Additionally, you can customize the level of Side Tone and Noise Gate.

    Noise Gate sets the custom loudness at which the microphone will pick things up, which is excellent for eliminating background ambient noises. Your friends will never know when you’ve got the AC turned on and running in the background with this microphone and it can eliminate even noisier inconveniences. As for Side Tone, this is a welcome feature for when you’re in more quiet environments since, as we’ve said, the passive sound isolation on this device is great, and not being able to hear yourself properly when you speak can get kind of jarring.

    As for the microphone itself, the only gripe you might have with it is that it’s not detachable. It’s cool how it automatically mutes itself when you flip it up and activates when you flip it down, but being able to remove it entirely would’ve been a welcome feature for many. Still, seeing as this is a headset that places gaming as its first priority, we can’t complain about this too much. It’s not like we’d take a headset this expensive outside when it wasn’t designed to endure the elements in the first place.

    Sound

    And lastly, we have the audio quality.

    This is the thing that makes it all worth it. Even if you’re underwhelmed by the lack of features, a battery life that’s average at best, or the poor range, the sound of this headset will simply not leave you feeling indifferent.

    As expected, considering the price and the manufacturer, the folk at Sennheiser have brought their A-game with this headset. We can unreservedly say that the Sennheiser GSP 670 features a certified audiophile-grade sound.

    And even though it was obviously made for gaming, everything sounds simply amazing on this headset: music, movies, you name it.

    To an untrained ear, it might sound underwhelming at first in games where there are lots of explosions but that’s because the bass here is very controlled. It doesn’t lack any punch, it’s just not boomy and it doesn’t overshadow other frequencies. This is awesome, although, once again, it might sound at first like a downgrade to an untrained ear that’s switching from a bass-heavy device for the first time.

    The presets have every situation covered, although you’re always welcome to make your own sound profiles if this is something you feel obliged to do. The 7.1 surround sound isn’t the best in class – which again hints towards this being Sennheiser’s first attempt at making a wireless gaming headset more so than anything else – but it’s still highly functional. Even the stereo mode has a grand soundstage that carries an expensive sense of depth and lets you pinpoint sound with minute accuracy.

    We just can’t say enough good things about it. It’s everything you could hope from a Sennheiser device – an audio quality that makes everything sound at its best.

    Conclusion

    Sennheiser GSP 670

    In conclusion, the GSP 670 is a great headset, but it’s hard to judge it outside the context of it being the first wireless gaming headset made by Sennheiser.

    One the one hand, Sennheiser has managed to waltz into this scene and completely obliterate the competition. In terms of just pure, audiophile-level sound it really is a one of a kind. It’s also supremely comfortable and quite ready to support your gaming endeavors for hours on end.

    But it also has an underwhelming if functional software, a battery life that’s hard to get excited about, and a wireless signal that can only be described as poor.

    Is it the best wireless gaming headset for $350? It is if you just want the best sounding headset on the market and you don’t mind the downsides we’ve just mentioned. But if you want a headset that’s a bit more versatile or one that you can carry over into the adjacent room or even the one next to that with impunity, then you should consider some of the alternatives.

    In any case, we’re glad to see Sennheiser tackling this market, as we’ve got great expectations from this manufacturer. And they’re already delivering as well. The recently released Sennheiser GSP 370 fixes all of the issues (except for versatility) we’ve had with the GSP 670, with its amazingly strong and far-reaching wireless signal and an unprecedented 100 hours of battery life. It’s a $200 headset so don’t expect the audiophile-grade sound that this headset provides, but if you’re interested in reading a full review of this product, you can do so here.
