Review: Sennheiser GSP 670

Over the years, I’ve come across several headsets that elevated gaming across consoles and handhelds. Too often though, those headsets ended up with one caveat: wires! I hate wires, and for good reason -they get in the way, get tangled up, or at worst, are prone to damage. The last good headset I had was the Sennheiser GSP 303, capable headset offset by the fact it had a long red cord that kept getting in my way while I played online.

As it were, Sennheiser is shifting its focus into wireless gaming headsets. So, when the luxury German audio company asked me to review the Sennheiser GSP 670, I jumped at the chance to see if this was going to be my main headset or something that I’d end up ditching in six months when something better came along. Thankfully, the former is the case, and I’ve spent the better part of a month putting the GSP 670 to work across PlayStation and PC, and even with Apple Arcade. There is a caveat though that is rather irksome for me – there is no support for Xbox.

Inside the Box

You’ll find the box has only the essentials necessary to get started. Alongside the headphones are a charging cable, dongle, and documentation. Out of the box, the GSP 670 feels like a premium product, with some heft to the headphones, and sits comfortably on your head.

No longer are you tied to your controller thanks to the GSP 670. Using a proprietary USB dongle, users sync via Bluetooth and can use the headphones on both the PlayStation 4 and PC for their gaming needs. The quality of sound Sennheiser products are known for is here. The closed acoustic design provides a warm, deep bass without compromising the mid-range and high frequencies. Which we’ve covered before with the GSP 303, a wired headset that’s to this day, one of the better headsets for gaming.

The GSP 670 offers a noise-cancelling microphone and mutes by lifting the boom arm up. The included Bluetooth allows you to pair the headset with your phone or tablet as well. Noise isolation is wonderful, and you’ll have one hell of time hearing anything but the direct audio. The included 7.1 surround sound works well and paired with Sennheiser Gaming Suite works best, you can tell where the sound is coming from. Comparably, turning this off and testing Call of Duty: Black Ops IIII offers a difference that is noticeable. You’ll hear steps far better with the option turned on.

As for battery life, Sennheiser’s claiming that the GSP 670 lasts upwards of 20 hours via Bluetooth and using intelligent battery management to determine when to automatically turn the headset on and off to maximize the battery life. With quick charge over USB, a 7-minute juice up allows for 2 hours of usage and can be used while charging. My estimates came with the suggested timeframe – I ended up getting roughly 12 hours of usage with the low-latency connection.

Design and Gaming Suite

Included as part of the experience is Sennheiser Gaming Suite – for Windows 10 PCs. This application allows you to customize the sound profiles for the headset to fit whatever it is you use them for. As previously mentioned in the review, the included 7.1 surround sound works best when paired with Gaming Suite, which offers several ways to customize the equalizer settings as well as little things like batter monitoring and


Another thing I really like about GSP 670 is the control scheme. The volume wheel for example also controls the power state, so by sliding it all the way down, you get a satisfying click that confirms your headset is off. A programmable smart button allows you to toggle equalizer presets. Plugging the headset into your PC and using Sennheiser Gaming Suite allows you to program the button.

Visually, I’m a fan of the aesthetic that the GSP line continues to improve upon. The headset is a bit weighty but offers comfort when resting on your head. Moreover, the black and grey colour scheme isn’t by any means drab and the choices to keep thing simple but elegant is a big plus for me. I don’t need anything fancy, and I’m glad Sennheiser understands that basic idea. Circling back to comfortability, the 2-axis metal hinges offer durability and the adjustable headband sliders regulate pressure and offer increased comfort.

Sennheiser once again shows why they are the best in audio, with the GSP 670 headset being the pinnacle of gaming accessories. That said, there are issues that in the future that should be addressed, like the lack of support for Xbox and Switch. There are few companies that stand toe to toe with Sennheiser when it comes to audio fidelity and the price is above average, but this isn’t just any headset. Sennheiser knows their clientele and this is the product for those who splurge on getting the best experience for their hobby – it is a luxury product and you won’t be disappointed.
