Sennheiser GSP 670 Review

While most of us here are veterans in the music industry, we are not completely out of touch. We are well aware that audio capture and reproduction equipment is now an all-important aspect of online gaming. And yes, most of us never do much gaming. But we have friends and family in the younger generations who have provided us with plenty of insight.

To game in the fullest sense, high-quality headphones and a mic are a must.

Indeed, the online gaming community has pushed major advancements in the area of headsets. Imagine being stuck with the same headsets the ladies at Ma Bell used 70 years ago for a full-on night raid on an enemy position. Cringe.

And so it was at the insistence of our younger counterparts that we came upon the EPOS | Sennheiser GSP 670 headset. And frankly, we were impressed.

What impressed us, you ask? Let’s find out in our Sennheiser GSP 670 Review…

Sennheiser GSP 670
Our rating:4 out of 5 stars (4 / 5)



EPOS and Sennheiser formed a joint venture to help bring Sennheiser’s audio expertise into new and lucrative emerging markets.

As of 2023, a new brand called EPOS | Sennheiser began delivering products tailored to the rapidly growing virtual business enterprise and online gaming sectors. It was a natural union. EPOS is heavily invested in listening and hearing technologies, and Sennheiser is one of the world’s best audio capture and reproduction companies.

Combine the two of them, and BOOM!

You get the ultimate piece of kit for your gaming as well as virtual business enterprise endeavors.

As a relatively “new” company, we are excited to see what they will offer in the near future.

But back to the 670 and what makes it a great headset…

The Build

Right away, you will notice that this headset is strong and sturdy. However, it is also surprisingly lighter, at just over 0.6kg, than you would think when you look at the size of it. It isn’t bulky, but it certainly isn’t a slim headset either.

This headset is a closed acoustic model. This means your ears are completely covered. One major advantage of this design is a high degree of noise suppression and sound isolation.

Relaxingly secure…

The earpads are made of a soft leatherette. They have a subtle flex, so they don’t pinch or press on your ears. The headband features adjustable sliders as well as a double-axis metal hinge system.

Both make it easy to fit your head comfortably and without an unnecessary amount of pressure. As a result, you can enjoy longer gaming sessions without discomfort.

Serious headphones…

You get some serious sound reproduction with this headset. It offers a generous frequency range of 10 – 23,000 Hz, which will accommodate the frenetic audio of a live online battle.

The headphones are also equipped with an SPL of 112 dB. This means you can rest assured the low-end won’t get thin, even when you start taking flak.

Basically, you are getting a high-fidelity sound. This is in large part due to the phones EPOS chose.

The microphone…

Here is where the Sennheiser half of the equation comes into prominence.

The GSP 670 microphone uses a closed dynamic transducer. However, it uses a bi-directional ECM pattern. As a result, you get a more consistent voice capture because the two directions are above and below your mouth.

Furthermore, this type of polar pattern also reduces pops and voice clipping via passive noise-reduction. Which we are sure never happens with your Logi headset. Right?

Made for gaming…

This is most definitely a Sennheiser mic. They have been perfecting specialized mics for years. And they knew exactly how this one would be used. So, they gave it a modest frequency response of 10 – 7300 Hz and a sensitivity of -47dB.

In other words, Sennheiser knew the mic would most frequently be used in loud and up-close situations. Therefore they put in a mic that would deliver crystal clear audio even during heightened volumes.

The Controls

Here we find one of the stand-out features. The controls on this headset are simple and intuitive. At least for the physical controls. We say that because there is a whole other digital way to control your sound. We’ll get to that in a bit soon…

Physical controls…

The only real controls on this headset are the volume knob and the mic boom. The volume is on the right earpiece and is a simple and sturdy means of adjusting levels.

The microphone is its own mute button. And kind of a channel selector in a weird way. Simply raise the mic to the upright position, and it automatically mutes. Lower it and you can either take an incoming call or drop back into the fray.

A premium user suite…

Another “stand out” feature is the EPOS Gaming Suite for Windows 10. More like a “left out” feature if you ask us. What about all the Apple users and those die-hard Windows 7 people? Maybe they would like access to this feature as well.

But enough complaining. For those with Windows 10, the customizable 7.1 surround sound suite is awesome. You can create your own sound for both the mic and the playback or live audio.

There are controls and presets for noise cancellation, microphone tuning, surround sound settings, and even a full equalizer. The result is an immersive, clear, and personalized audio experience.

The Battery

Sticking with the more physical side of this headset, we find a reliable and long-lasting battery. It makes use of Intelligent Battery Management. In other words, it monitors the life of the battery and will automatically power on or off as necessary.

Another nice aspect is the longevity of the battery. When using Bluetooth, you will get 20+ hours of playback. For wireless, it is 16 hours. And for standby, it is 200 hours. Not too shabby.

The Connections

Here we are at a crucial section. And what can we say? The connections performed marvelously. Whether Bluetooth, wireless with a dongle, or the wired USB cable, there was not any significant signal loss.

Dual Connectivity…

Touted as one of this headset’s crowning achievements, it did not disappoint. Using the USB dongle for the game connection and paired via Bluetooth with a smartphone, you can switch between them with relative ease.

Each signal came in as it should. The surround sound setting for the game did not bleed over to an incoming call. Likewise, talking on the phone does not slip into your game.

Stable connection, superb sound…

Additionally, both the Bluetooth and USB dongle wireless connections deliver on the low-latency promise. The connection is lag-free, which means both you and whoever you’re talking come through loud, clear, and uninterrupted.

Overall, this headset has a level of wireless sound quality that puts many others to shame. If this is the kind of wireless sound EPOS | Sennheiser is going to be producing, count us in.

Sennheiser GSP 670 Review Final Thoughts

This headset is particularly geared for gaming. And in that department, it excels. While we are not big gamers ourselves, we can recognize high-quality audio equipment when we see it.

True, this headset has a price point that most gamers would rather spend on a processor or graphics card. But, in all fairness, what you’re getting for the price more than compensates.


We are impressed with the low-latency considering it is billed as a wireless headset. Often, wireless headphones suffer from latency issues and diminished sound quality. And it looks like the GSP 670 may have just raised the bar on both accounts.

We also really like the built-in microphone. It is flexible and still sturdy. Sennheiser is a big name in the microphone industry, and they have come through once again.

Sennheiser GSP 670 Review

And finally…

We have to give props to the design and build of this headset. It is very comfortable and quite sturdy. That is always going to be a bonus when you’re spending hours playing Call of Duty or PUBG. Your Twitch streams will be lit with this headset.

See? We’re not all grumpy old geezers.

Until next time… Game On!

About Joseph L. Hollen

Joseph is a session musician, writer, and filmmaker from south Florida. He has recorded a number of albums and made numerous short films, as well as contributing music to shorts and commercials. 

He doesn't get as much time to practice and play as he used to, but still manages (just about!) to fulfill all his session requests. According to Joseph, it just gets harder as you get older; you rely on what you learned decades ago and can play without thinking. Thankfully that's what most producers still want from him.

He is a devout gear heat and has been collecting musical instruments all his life. As his wife, Jill, keeps on saying, "You're very good at buying nice instruments, but terrible at selling them!".
