Sennheiser GSP 670 Review

Recently, I had been contacted by my colleagues at Sennheiser to work with a new pair of headphones. That headset is the Sennheiser GSP 670, the next step forward for Sennheiser as they officially move into the wireless gaming peripheral market.

The thing that Sennheiser focuses on is the sound experience. They have always been great at providing an audiophile-worthy experience, and with the GSP 670, we finally have a “gaming” headset that doesn’t look outlandish. And look, I get it, RGB stuff sells and people want that nowadays. I can definitely appreciate a design, however, that favors a more muted color scheme that prevents me from looking too edgy in an academic setting.

Talking about the design, this is something that has not changed since the GSP 600, 500, and 550, with the major exception being the inclusion of wireless playback. That makes it intriguing that Sennheiser chose to forego the option of having a wired functionality at all, essentially forcing the wearer to go completely wireless. There will always be complaints of wireless headsets that lose some of their audio quality in the switch to wireless, and I’ll note that the only audio issues I had was when I was moving away from my PC to attend to something on the other side of the space I’m primarily using the headset in. The signal remains strong but once walls or barriers start getting involved, the signal gets a little bit weak and the audio starts to break a bit.

Making a return on the GSP 670 is the self-adjustable headband tightness. I find that the best way to describe this feature is an adjustment to the force that the earphones clamp on your head. One of my biggest gripes with the GSP 600 when it came out several years back was that it felt way too tight. It was uncomfortable for longer sessions, I’ll admit, even with having a small head size. The GSP 500 was a better fit, but it finally feels like Sennheiser got it just right with the GSP 670s. The ear cups are made of leatherette and fit well with my ears and the force it exerts on my head is a lot less noticeable than I remembered my GSP 600s having.

Something that does baffle me, though, is the price of the headset. After tax, it’s close to being on its way to $400. For a headset of that price, I honestly am surprised that the headset still has its plastic design. Even with its plastic design it’s also fairly heavy at 398 grams, the heaviest headset compared to its other siblings. For a headset that is this expensive, I’m surprised that Sennheiser didn’t opt for a metal headset all around, which would have been a nice touch.

The sound quality makes up for this, though, and that is the primary payoff here for a headset. We finally get a return to the closed sound stage, which means that all the noise is going to stay inside the earcups without leaking out. So, that sound, oh boy that sound. I spent a good number of hours listening to music like the ever delightful Xenoblade Chronicles 2 soundtrack, played games, and watched movies. The crispness and clarity that the GSP 670 offers is unlike any other gaming type headset that I’ve put on my head, and that says a lot in a crowded and competitive lineup of already impressive headsets. There is a level of coldness and cleanliness that comes with Sennheiser’s audio, and that trademark has not been lost in this headset. Words are actually failing me here. The 670s have a fantastic sound to them… good enough to get me to think a little bit more about turning my head away from that $350 price tag.

The microphone also sounds really good too, with people saying my voice sounds really clear. I can’t say how handy it is to be able to mute my microphone just by flipping the microphone up.

With wireless headsets, the other big question that comes up is, just how long is the battery life? I have gotten about 17 hours average of battery life on them, through a combination of games, music, and movies. It’s not bad, considering Sennheiser says you can get about 16-20 hours of life. It charges with a micro USB cable, which is a little bit disappointing with a lot of companies moving to the more “modern” USB-C, but I only say that it’s disappointing because most of my devices are now USB-C powered. So take that with a grain of salt.

Sennheiser has made a solid design less edgy with its darker, muted color scheme, which is great news. It’s a bit of a bulky headset that takes a little bit of time to get used to, but once you do, it’s going to stay comfortable on you for a while. The only true problem I have with it is its price. $350, no matter what way you look at it, can buy you a lot of things, including some great competitor headsets. I think, though, that once you swallow that price of entry, you will be heavily rewarded with some of the best sound you can ask for in a wireless headset.
