Sennheiser GSP 670 Wireless Gaming Headset Review

Sennheiser GSP 670 Review

After our comparison test of low-budget headsets, the Sennheiser GSP 670 now has to show whether it is worth spending more money on headsets.

Design and scope of delivery

Even the packaging of the high-end headset looks very high quality. The Sennheiser headset arrives at customers neatly packaged and softly padded. In addition to the wireless headphones, a 1.5 m long micro USB cable, a USB wireless adapter, and instructions are included in the scope of delivery.

The black and gray GSP 670 is very modern and, despite the lack of RGB lighting, anything but reserved. We like that. The Sennheiser top model is bulky and more futuristic compared to the inexpensive entry-level model GSP 300 (test report). This visual impression is also confirmed on the scales. At almost 400 g, the headset is more than a bar of chocolate heavier than the GSP 300. Although the headset could be used to listen to music with a smartphone on the go, the model is too conspicuous for us to be used in public.

What is immediately noticeable are the ear cups that are hung on just one sturdy metal bracket. Most headphones use two suspension points. Due to the design of the GSP 670, the two headphones are very flexible and lie very reliably on the ears. The length-adjustable headband is not completely closed for better ventilation and is softly padded. The contact pressure can be adjusted using two sliders in the headband. The two soft ear cushions are made from a mixture of synthetic leather and fabric. They are sufficiently breathable and interchangeable.

The foldable microphone boom on the left auricle is relatively wide and striking. Part of the arm is flexible so that the position can be easily adjusted. The microphone is deactivated when it is folded up.

A large adjusting wheel for adjusting the volume is located in the middle of the right headphones. The stiff wheel doubles as an on and off switch. Next to it is a second small adjusting wheel for the microphone volume. Finally, a button and a slider bring the headset into Bluetooth pairing mode and are used to announce the battery’s charge status.

The quality is high according to the price. Both upholstery, metal elements, and plastic parts leave a positive impression. We also liked the stiff volume control in the test. It looks more massive, durable, and of higher quality than the volume control of cheap headsets.


The GSP 670 works both on a PC and on the Playstation 4. There are three connection options for both devices. The headset receives its signals either via a micro USB cable, via Bluetooth or via radio. Since we prefer wireless convenience, we only use the USB port to charge the battery.

The connection via a USB wireless adapter works without problems on both the Playstation 4 and our PC. However, we only achieve the specified range of 10 m with a line of sight. The first disturbances occur when walking into the next room.

Pairing via Bluetooth connection also works right away. Once put into pairing mode, the GSP 670 can be paired immediately with a PC, Playstation, or smartphone. The connection is stable – at least within a 10 m radius of the playback source. Significantly less interference occurs in the adjoining room than with the radio link. A jack connection is not installed.

Audio quality

The sound of the GSP 670 is great. The tweeters, midrange, and woofers are harmonious and neutrally tuned – atypical for a gaming headset but very pleasant. The bass is powerful and warm. Mids and highs are clear and powerful. Even fine sounds and background noises can be heard well. The Sennheiser headset is not only suitable for gaming but also for listening to music or watching TV. The sound direction is easy to determine, even in stereo mode. For our taste, the maximum volume should be a bit higher.

The free software makes it possible to change the sound settings according to your ideas and create surround sound. This emulated 7.1 surround sound enhances the spatial impression but is noticeably at the sound quality and volume expense. The midrange, in particular, loses its intensity, and the entire sound reverberates. However, the Sennheiser Gaming Suite is only available for Windows. Playstation 4 or macOS users have to be satisfied with the very good standard settings. Ultimately, we prefer these anyway.

The outside of the ear pads is more massive than the actual padding. This helps to ensure passive attenuation of ambient noise. As a result, the GSP 670 shields the player much more from the outside world than the cheaper GSP 300. Of course, the user is not completely shielded, but not much can be heard from the surroundings.


The microphone does a very good job. The built-in ambient noise cancellation works amazingly well. Our interlocutor cannot hear even a loud dishwasher running in the background. The transmission of the voice is clear and free of interference. The volume is sufficient and can be easily changed using the dial.

How close or far the microphone is from the mouth hardly affects the voice quality and volume in the test. If you want to mute your microphone, fold the microphone boom up. When no more sound is transmitted, you can tell by a slight resistance when folding it up.


The GSP 670 is very comfortable and sits thanks to flexible ear cups and adjustable contact pressure very reliably. The high weight and tight fit are initially unusual. Anyone who has previously used light, loosely fitting headphones will have to switch to this model. But we don’t find that annoying. On the contrary: In connection with the good passive damping, you feel well equipped with the GSP 670. Headset on, world off, game on.

Even after several hours of use, the ears remain dry. Despite the soft and shielding padding, the headphones are sufficiently well ventilated.

Battery and technical data

According to Sennheiser, the internal battery of the GSP 670 lasts 20 hours when using the Bluetooth connection and at least 16 hours when using the USB wireless adapter. In practice, the service life is only slightly below the manufacturer’s specification (when using Bluetooth). This means that the battery power is sufficient for gaming weekends but not record-breaking. The integrated shutdown function works well and helps to save the battery. If the headset is switched on and not worn, it will switch off automatically after a few minutes.

After less than ten minutes on the charging cable, the battery has enough power again for two hours of operation.


The GSP 670 is a successful top-class gaming headset. In addition to the very high sound quality and the good microphone, the stylish design and comfort are also convincing. The headset also scores well in terms of handling and wireless connection. So if you want to concentrate fully on your game and enjoy the first-class sound, this is the right place for you.
