Sennheiser GSP 670 Headset Review

Wireless tech is a funny thing. In one respect it is everywhere in our lives. Everything is wireless, we expect it and yet certain aspects of it are still really expensive and premium.


Wireless audio is one such area where the price really doesn’t seem to come down ever and most of the key manufacturers will have a range of wireless headsets covering the mid-range to the high-price sectors.


Nobody wants a wired connection – although conveniently we forget that a wired connection is pretty much lag-free and in competitive gaming that can give you those milliseconds of an advantage and mean your brain doesn’t have to adjust to what it is hearing.


With all that in mind let’s have a look at the top-of-the-range Sennheiser GSP 670 today – a wireless gaming headset from a pro brand that promises to alleviate some of those latency issues while delivering an aural experience that can’t be matched. Let’s go.

Let’s get the jargon out of the way first. The GSP 670 claims to offer lossless Bluetooth connection with a long-range of 10 metres as well a proprietary low-latency technology to enhance your gaming audio experience. More of this later.

They are also boasting a battery life of around 16-20 hours and a fast charge capability that gives you an extra two hours juice after just seven minutes but maybe, in this case, the biggest selling point of all might just be the brand itself.

Sennheiser is synonymous with quality audio headphones. That’s been the case for decades. Sennheiser phones have been the choice for music studios, radio stations and audiophiles the globe over for a very long time, so we should rightly be just a bit excited that this level of expertise is now within our reach for our PCs.

I say within our reach but that might not be the case for everybody. These are not cheap, coming in at the price of a semi-decent GPU but it’s likely if you are in the market for a high-end wireless headset, you probably won’t be too concerned about that, especially when you take into account that these are - spoiler alert - about as good as you can get on the market today.

There is a caveat there, new sets are coming out all the time and the GSP 670 has set itself up to be the benchmark for others to try and take down. It won’t be easy though, you realise that from the minute you slide them over your dome.

Adjusting the grip on your skull is simply performed by altering the sliders in the headband. If you prefer them so tight your eyes are bulging, that’s fine, crack on, or you can loosen them to taste.

The earpads feel lovely. They are covered in some form of synthetic suede type material and lushly padded, which also isolates external noise surprising well.

To the left-hand side there is a boom-mic (unfortunately not detachable) that swivels out of the way easily - and not only that but it mutes itself when you flip it up too. A nice touch.

The right-hand earcup houses my favourite part of the whole set-up the volume and on/off know - A large dial with a terrific amount of resistance built into it that really does fee premium.

A complete turn anti-clockwise will turn the unit off, at which point the light on the included dongle blinks out of existence to reassure you that that your battery is now safe from drainage.

Rotate it the other way, the light comes back on, a lady pipes up in your head to say the dongle has been found and you are back in business. It’s absolutely seamless and the feature I found the most compelling.

I have been using a premium Corsair wireless headset for months and it has nothing on this. I’ve had hassles trying to get it to be my default device, come to find it drained completely and it just doesn’t feel as nice. It’s not as expensive but it’s still one of the more popular high-end models.

As most PC users who use their rigs for multiple things will know it’s pretty easy to rack up a whole host of sound devices in Windows and things can get confusing very quickly.

A quick look at my sound devices in Windows show my speakers, a couple of headsets, an Oculus Rift a Blue Yeti microphone, my Razer Ripsaw capture card and so on - it’s confusing as hell. For the GSP 670 to be able to sort its way through that mess and just work is great, and in my experience at least, not the norm with other headsets.

Aural pleasure

As for audio quality, it’s as good as I have heard from a set like this. I have wrecked my ears over the years but I was hearing sounds and nuances in Apex Legends that I genuinely have never heard before. You can easily switch between stereo and faux 7.1 with the tap of a button or through the very in-depth software package you can use to tweak.

Speaking of the software when I booted it up and connected the headset via USB for a quick charging session the programme reported that I h1ad new firmware available for the cans, a software update and a firmware update for the dongle.


The headphones updates fine, as did the software but I haven’t been able to update the dongle firmware – it times out after about 10 minutes but I’m sure that will get sorted at some point. I also couldn’t easily find a changelog to help me decide if I wanted to update. I’m always inherently nervous of firmware updates!

I wanted to test out the range and as I am currently working from home and socially distancing the living daylights out of myself that involved heading downstairs. Once out of the line of sight of the dongle the audio started to drop in and out but I was still able to pick up an, albeit crackly, signal downstairs and in my kitchen. As soon as I returned upstairs though everything kicked back in just fine so for me, it performed admirably.

Besides a couple of games where the sound was second to none, I also whizzed some music through it in Traktor Pro DJ to check latency and bass. Again it worked flawlessly. They aren’t necessarily headphones you would just away from your home setup due to the non-detachable mic – they aren’t public transport wear that’s for sure but you can connect them via Bluetooth to your phone should you fancy.


Are they for everybody? Well, they are and they aren’t. If you are looking for a top-drawer wireless headset and money is no option then yes. I’d buy them immediately. If you are thinking, do I really need to drop $300 on headphones/ Then maybe not?

Having said that when you look at the price of AirPods and compare the sound and everything else on offer here they start to look a bit more reasonable.

I’m not sure you are going to find a better set out there right now. They are lovely, well-made and suitable heavy. Audio response is terrific and they work like a charm. 

Maybe it’s that present you deserve to buy yourself with all the money you are saving not going out.
