Product Information

Even if Sennheiser is not at its first gaming headset, it is the initial wireless reference of the manufacturer which has just renamed its EPOS gaming branch. This headset arrives on a mature market made up of many references and driven by particularly tough competition.

Sennheiser announces an autonomy that can vary from 16 to 20 hours depending on the connection mode (Bluetooth or owner). In practice, we never managed to exceed 18 hours of use with a full charge only via the proprietary wireless connection, and 15 hours with the double connection with Bluetooth.Known for a long time for its Hi-Fi headphones, Sennheiser has also distinguished itself with the general public in the world of video games. The German brand broke through with its Game Zero and Game One gaming headsets, then confirmed its expertise five years later with its GSP line. The GSP 670 did not hold any surprises for us in terms of comfort. The sensations provided are in fact similar to those of the GSP 600. The headset is easy to handle and easily finds its place on the head, despite its size. Its wide and soft ear cups encompass the pavilions well and the pressure points are correctly distributed. The timbres are perfectly respected and defined, we benefit from a very good effect of presence and a sharp sound, without it being aggressive.

Thanks to Sennheiser’s unparalleled record when it comes to aural engineering, the headset is a dream to use in audio-rich games. First-person shooters and survival horror games highlight the GSP 370’s 20-20,000Hz frequency range the best, but the headset makes pretty much any PS4, PS5, or PC game shine out of the box. The GSP 670 also comes with an advanced, solid metal hinge system, adapting the headset to any head shape and guaranteeing a perfect fit. The upside, though, is comfort: both the headband and the earcups sit on an average-sized head without distress, and the width of the band allows even larger-headed players (like the reviewer) to enjoy lengthy sessions without discomfort. If you don’t mind faux leather, the earcups are perfectly functional, and the way they operate and noise-cancelling muffs, too, should be lauded. The sound is very different too what you’ll find on most gaming headsets. This may put off some regular, non-audio conscious buyers as the most noticeable difference is how controlled the low end is. Unlike competing sets, such as the Arctis Pro which push the low end to the point it can wonder intrude on other parts of the sound, the Sennheiser GSP 670 keep it under permanent control. This gives it a far precise sound than most headsets, but can initially feel like it’s less powerful to an untrained ear. The Sennheiser GSP 670 is the result of years of development and is not only our first wireless headset, but also the best wireless headset for gamers to date. It combines all the strengths for which Sennheiser is well-known all over the world: maximum wearing comfort, audio performance of the highest level, and clever features that you couldn't do without," says Andreas Jessen, Director of Product Management Gaming at Sennheiser Communications A/S.

The mic is another stand out feature and one of the biggest differentiators between the GSP 670 and Arctis Pro. The Arctis Pro sounds great, but like most SteelSeries headsets its mic was a little weak, and had a tendency to distort. The GSP 670’s noise cancelling mic is blissfully clear by comparison, and one of the best I’ve tested on a gaming headset. Even during heated, loud, online matches my team reported being able to hear me loud and clear, making it a great option for competitive gamers. We greatly appreciate its presence, which is not always guaranteed on gaming headsets. However, this wheel is a bit painful to use, because there is no stop to find the central position. The single “smart” button can be assigned to toggle EQ profiles or enable/disable virtual 7.1 surround. Visually the Sennheiser GSP 670 fall between the two extremes you normally see on a gaming headset. Bluetooth integration is also of little interest in a configuration with a dual proprietary wireless/Bluetooth connection, because there is no way to switch manually and easily from one to the other, and even then less to mix the signals. Only a call on the device connected via Bluetooth will force the switch. Once done, it is not possible to easily return to the signal coming from the USB transmitter. In our case, we had to manually disconnect the Bluetooth source or turn the headphones off/on.

The sound profile of the Sennheiser GSP 670 shares a lot in common with that of the GSP 600, its wired cousin from the same manufacturer. This gaming headset delivers an equally natural and immersive rendering. Sennheiser and its GSP 670 first test in the wireless version was generally successful. These headphones retain the advantages of the excellent GSP 500 and 600, with good sound reproduction (although a little less controlled) and above all an extremely high-performance microphone. The headset comes with the aforementioned USB dongle and a charging cable, but that's it. No case or stand is included. Like the GSP 370, the GSP 670 has no place to store the tiny dongle when it's not in use. Microphone The microphone of the GSP 670 fulfills its mission brilliantly and is even placed as a reference among wireless headsets. We just can’t find anything to complain about. The signal is powerful, clean and perfectly balanced. We live and breathe audio. We are driven by the passion to create audio solutions that make a difference. Building the future of audio and bringing remarkable sound experiences to our customers – this is what the Sennheiser brand has represented for more than 75 years. While professional audio solutions such as microphones, meeting solutions, streaming technologies and monitoring systems are part of the business of Sennheiser electronic GmbH & Co. KG, the business with consumer devices such as headphones, soundbars and speech-enhanced hearables is operated by Sonova Holding AG under the license of Sennheiser.
