Sennheiser has shown to be a respectable manufacturer of headphones, but it is less well-known when it comes to gaming headsets. We like the $200 Sennheiser GSP 370 because it demonstrates that the business can provide good audio in a wireless, gamer-friendly compact with a good boom mic. Sennheiser's top-of-the-line gaming headset, the Sennheiser GSP 670, costs $319 and has a beefier design than the Sennheiser GSP 370. It also has Bluetooth connectivity, allowing you to use it with your phone, PC, and PlayStation 4. If you can get beyond the high price, the Sennheiser GSP 670 sounds great and feels great.

Sennheiser GSP 670 Gaming Headset


The Sennheiser GSP 670 is much bigger and thicker than the GSP 370, with a more robust, sci-fi military look that builds on that headset's design. The skeleton metal arms that join the large grey earcups to the headband give some pivot and bend owing to two hinges. The oval earpads are large and filled with soft memory foam, with faux leather on the sides and a softer, suede-like material over the top. The mesh fabric covers the bottom of the headband, which is softly cushioned.

You may modify how the headset fits on your head by sliding two plastic sliders over the top of the headband to distribute the weight more toward the sides or the centre. While the GSP 670 may appear heavy at first glance, the ample ear cushioning and ingenious weight sliders offer a comfortable fit that allows you to use the headset for long periods of time.

The left cup features a smooth plastic circle on which the massive, hefty boom microphone is fixed to easily flip up and down, while the right cup has a ridged circle that functions as a combination power button and volume slider. After rotating the dial slightly to the left to switch on the headset, you may keep spinning it to raise the volume. It's considerably stiffer than the volume dial on the Sennheiser GSP 370, and it gives no indication of whether you're going to switch the headset off or merely turn the volume down.

The micro USB charging connector, as well as a status LED and a Bluetooth connection slider, are located on the bottom edge of the left earcup. On the bottom edge of the right earcup is a conversation volume slider, as well as a programmable smart button that defaults to switching between equalisation settings.

There are three distinct sorts of connections that the GSP 670 may use. You may listen and chat through your PC or PlayStation 4 with the bundled wireless USB dongle. The accompanying USB-to-micro-USB connection may also be used to connect the headset directly to either device (which is fine for PCs, but might be a bit short to reach your PS4 from the couch). Finally, you may connect the headset to your phone or any other Bluetooth device through Bluetooth. There is no 3.5mm connection choice on the headset. The USB dongle and charging cord are included with the headset, but that's all. There is no case or stand included. When not in use, the GSP 670, like the GSP 370, has no place to keep the little dongle.


The boom microphone is sensitive and capable of recording your voice clearly. Test recordings sounded clean and sharp after a few changes to the settings, with no discernible sibilance. During recordings, the noise-canceling microphone successfully masked out modest background talk in PC Labs.

Check the Sennheiser app's microphone functions if your voice sounds odd at first; it defaulted to a Warm Voice Enhancer option that made test recordings sound compressed, but removing the feature cured the problem. It's a good microphone for streaming and recording with a little practise, but if you're serious about capturing your voice, you might want to invest in a specialised USB microphone.

Performance of Music

Given its Sennheiser history, the GSP 670 is pretty good when it comes to playing music. The bass drum strikes in The Knife's "Silent Shout," our bass test track, come through with a tangible intensity that doesn't quite reach head-rattling subwoofer levels, but nonetheless makes itself felt in the lower frequencies. When you set the EQ to the Sennheiser app's Music preset with sculpted highs and lows and increase the Reverberation setting, the bass sounds very forceful. The bass does not distort even at these settings and maximum volume levels.

On the GSP 670, Yes' "Roundabout" sounds fantastic. Due to great high-frequency finesse, the beginning acoustic guitar plucks have plenty of string texture, and when the electric bass comes in, it sounds snappy and aggressive without dominating the rest of the hectic mix. The guitar strums, vocals, and drumming all stand out, and each element is given equal prominence.

"Born Too Slow" by The Crystal Method also shines on the headset. The shrieking vocals and guitar chords take centre stage, yet the percussion balance the music by bringing forth the bass force. Every part of the driving backbeat is given ample attention in the lows and mids, ensuring that no detail is overlooked.

Performance in the Game

On the Sennheiser GSP 670, the noise of motors in Forza Horizon 4 comes over loud and clear. Supercars' whine and off-road vehicles' growl sound powerful, with substantial presence in the mids and highs to distinguish each engine. The plastic clatter of Lego pieces in the Lego Speed Champions map is full of fine, clacky texture, yet smashing against obstacles and splashing in water sounds tremendous.

On the GSP 670, Gears 5 sounds fantastic. The shotguns and heavier assault rifles, in particular, carry a lot of punch. Combat sounds are powerful, with a strong low-frequency response to propel the action. The skittering of Pouncers as they neared me attracted enough attention that I could clearly hear them. The headset's simulated surround sound doesn't have a lot of directional imagery, but it does have enough information and decent stereo panning to get a feel of who's fighting where.

Gaming Audio of the Highest Quality

Thanks to Bluetooth connectivity, the Sennheiser GSP 670 is a superb wireless gaming headset that works with your PC, PlayStation 4, and smartphone. Although the heavy-duty gaming appearance may deter you from using it in public, it's versatile and practical. It's a bit pricy for a headset that doesn't come with a dock or even a compartment for the USB dongle, but the build quality and audio performance are worth it.

The Steelseries Arctis Pro Wireless, which costs $10 more than the GSP 670 but has a base station with plenty of inbuilt settings and two swappable batteries, as well as 3.5mm and Bluetooth compatibility, is another option for full-featured, strong wireless sound. The $150 Turtle Beach Elite Atlas Aero wireless speaker is a good performance for less than half the price of the GSP 670, while the $100 Razer Nari Essential is a highly capable budget choice.
