Review | EPOS Sennheiser GSP 670 – A while ago we got to review the GSP 370 and we were very excited about this headset. Back then, as with most headsets, there was a barrier that there were limited options on the PS4 to get the most out of the headset. Mixing the party chat was not possible and gaming wired via a DualShock 4 is simply not fantastic. The GSP 370 was otherwise an excellent headset in its price range and is still recommended. Now we have got our hands on the big brother, the GSP 670. Although it has been on the market for a while, it is still worth paying attention to and seeing if it is a good product to get.

Elegant headset from EPOS

The GSP 670 has a design that you know from the GSP 370, nice and sleek, but also with a certain finesse. The somewhat plastic look is a bit more refined thanks to the beautiful finishes on the earcups. The metal construction that gives the earcups room to move at the headband is black, so that the whole headset has a nice dark appearance. Very nice and neat to the eye, while the design has the typical ‘gamer-like’ look of EPOS | Sennheiser has. The headband has the option in the middle to make the round shape more straight or convex with two sliders, so that it adapts more to the shape of your head. Of course you can also set the earcups longer or shorter.

With the GSP 670, the microphone is difficult to bend towards your mouth and it also has the well-known leather finish, like most of the EPOS | Sennheiser headsets. At the right earcup you have a large volume button and you can flip up the microphone to mute it. When lowering it, you can immediately use the microphone for speech, which is somewhat self-explanatory. The headset is a wireless headset that you can connect to your PlayStation 5 (or 4) with a USB dongle (GSA 70). So nice and plug & play, because you put the dongle in and your PS5 lets you get started right away. If you are interested in using it for PC, this is of course possible and it is just as easy. If you want to charge the headset, a micro-USB cable is included.


The GSP 670 does great things in every way. A nice bass, but not too much present, while you have a nice sound in a complete whole. However, it is a pity that due to a little too little treble it is really an all-rounder. It has just a little too little bass for the deep sound, but this gives the other tones a little more distinction. At busy times in a game it may therefore be that you get a somewhat ‘muddy’ presentation. Take this with the nuance that it is minimal, because we can not pay the headset considerably. Nevertheless, an important point to keep in mind if you are looking for something more purity.

To put it in perspective, the GSP 370, for example, lacks a bit more bass than this headset, but you get more clarity in return. The GSP 670 could have been more daring in that respect and pumped a little more bass, which the headset can also handle. With third party software we boosted the bass a lot and the treble a bit. As a result, the sound came into its own more, the muddy ‘problem’ was reduced and the bass was nice and firm while nothing drowned out. That it can be done via external sources shows that EPOS | Sennheiser missed an opportunity here, but that does not alter the fact that the GSP 670 is still excellent as a beautiful all-round headset. Moreover, the spaciousness is fine and you can easily determine from the different directions whether someone is trying to hit you.

Fine and flexible in use

We do put the GSP 670 on the rack and make a critical note here and there, but this is of course also because it is not a cheap product. The headset costs around € 300, which is simply very hefty and if you look at the market in that price range, we have to be strict. Much of the price, however, lies in the fact that it is a wireless headset, with which it scores points. The indicated operating time is 24 hours on a full battery and this seems to be plausible. You can certainly expect a nice 20 hours, with an hour more or less, depending on how hard you have the headset in use. Charging does not take very long and if you do not have the patience to wait an hour or two, you can charge 2 hours ahead with just 15 minutes. After all, you can continue to play via a cable, albeit somewhat less comfortably.

I can say nothing else than that the GSP 670 is an interesting and well-cared-for product. With the EPOS | Sennheiser headsets seem like, due to the matching designs, everything is the same. But appearances can be deceiving. The GSP 670 is extremely comfortable and just very comfortable. Please note that it is a fairly heavy headset of almost 400 grams, which can be a problem for some gamers. If this is not a problem, then it is definitely recommended for longer sessions. The earcups are also fine in size, so you won’t feel any unnecessary pressure on your ears.

EPOS Sennheiser GSP 670 – Conclusion

‘Jack-of-all-trades, but master of none’ is a bit of what suits this headset. You have a very solid product, but it is not a standout. And that is absolutely not bad, within sound you have different signatures and this is just very balanced. If you want more bass, look further and the same applies if you want more clarity. For something in between, you have a very interesting choice with this headset. The approximately 24-hour battery ensures a nice cable-free experience and you also spend extra money for that. Because the headset has a hefty price tag and within this category you can find other stuff that can excel in more areas.
