Sennheiser GSP 670 Wireless Gaming Headset Review

If you’re into audio, you’ve undoubtedly heard of the Sennheiser brand. The company has released its first wireless gaming headset, the GSP 670, and it promises to deliver “gaming for audiophiles.” Audio in video games has come a long way from the bleeps and bloops of 8-bit sound effects from an original Nintendo Entertainment System, or MIDI files serving as background music in PC games. Nowadays, game developers are producing truly cinematic masterpieces that demand high-quality audio for the complete experience.

Not only are games like God of War and Horizon Zero Dawn graphically stunning in 4K, their atmospheric soundtracks, realistic sound effects, and voice acting add so much to your adventure. Or perhaps you’re a PC gamer and prefer to spend your evenings in Fortnite or Apex Legends—even then, you’ll want a high-quality headset so you can tell where the shooting or footsteps are coming from as that ring closes down on you. More importantly, communicating with your teammates and friends are a major part of an online gaming experience, which is where having a nice headset becomes important.

This new wireless headset builds off Sennheiser’s GSP 600, which is a great wired option but it comes at a high price. To some, the GSP 670 isn’t much different with a retail price of $349.95, but the wireless market is a bit different. There are other high-end wireless options available that cost $300 or more, which means the GSP 670 has direct competition—such as the SteelSeries Arctis Pro Wireless and the Astro A50.

I was fortunate enough to get my hands on the new Sennheiser GSP 670 and was excited to put it to the test against the SteelSeries Arctis Pro Wireless, which I believe is its closest competitor when it comes to features. If you take a look around the internet, you’ll see that the Arctis Pro Wireless is widely considered by many as the top wireless gaming headset currently available. Does the Sennheiser GSP 670 have what it takes to dethrone SteelSeries?

What’s in the Box?

Before we start going in depth on the headset itself, let’s take a look at what’s included in the box. In true Sennheiser fashion, it’s fairly minimal. You get the headset, the GSA 70 USB dongle, and a 1.5-meter (5-feet) micro USB cable to charge the headset. That means it’s extremely simple to setup on either your PlayStation 4 or PC (the headset is not compatible with Xbox One consoles) by just plugging in the USB dongle. There’s also your normal documentation, including a fairly basic instruction manual.

Build Quality

If you’re paying more for a headset than you do a console, it’s understandable that you’ll expect a certain level of quality. The Sennheiser GSP 670 delivers in that department, with the headset feeling solidly built while staying lightweight. Generally, wireless headsets weigh more than wired counterparts, mainly because they need to incorporate a rechargeable battery within the headset.

With its plastic and metal construction, the GSP 670 manages to stay balanced in the weight department—but we’ll talk about comfort and adjustability in a minute. The microphone feels sturdier than other wireless headsets that have retractable mics, while the on-headset controls are refined and feel great to adjust, such as the large volume knob and voice chat / communications volume wheel.

The ear cushions on the GSP 670 (GSA 601) are the same used on the GSP 600. They’re made from thick memory foam and covered in leatherette, while a suede-like material can be found on the part that touches the ear. The suede-like material adds a bit of a luxurious touch to the build quality of the headset, although we’ll address their cons later on.

There isn’t much to complain about when it comes to build quality on the GSP 670. In short, the headset feels like a premium product and justifies the price tag.

Comfort and Controls

The fit and comfort of the GSP 670 is very similar to the GSP 600. For some, that means this headset may feel a bit tight on the head, but it does offer plenty of adjustability. Up top, the split memory foam headband features two adjustable sliders so you can distribute the pressure a bit. There’s a two-axis metal hinge yolk design for each ear cup, offering some mobility for increased comfort. These features, combined with the adjustable headband, ensures you get a well-balanced fit even if it takes a bit of adjustment.

Once you get the headset properly setup, it’s extremely comfortable even for long gaming sessions. Initially it did take a bit of getting used to, especially since I’ve been using the Arctis Pro Wireless daily for over a year. After a day or two of use however, I hardly notice that the headset was being worn. I’d give the GSP 670 an edge in comfort to the Arctis Pro Wireless, and comparable to the Astro A50, which many consider as the most comfortable headset for gaming.

The headset isn’t perfect however, as the ear cushions do get hot compared to other headsets. It’s a minor complaint, but the suede-like material can make your ears sweat during long gaming sessions and it’s something you’ll notice as soon as you take off the headset. In exchange however, these ear cushions do isolate outside noises better than other headsets—whether that’s a benefit is dependent on your gaming conditions!

There aren’t very many controls on the headset itself, and the main one you’ll be using is likely the volume knob. Interestingly, it also doubles as your way of turning the headset on and off, meaning it doesn’t have a separate power button. If you don’t like reading instruction manuals, that may seem a bit confusing at first, since there’s a button located right underneath the volume knob. That button however, is a toggle button you can assign through Sennheiser’s software if you’re using the headset on a PC. For now, you can either set it to toggle between your profiles or the 7.1 surround sound.

What we really liked about the volume knob is its resistance. It’s something Sennheiser really got right with this headset, allowing you to fine tune your volume in small increments. It doesn’t turn loosely like other volume knobs and feels great for adjusting. The communications wheel, which is also located on the right ear cup with the volume knob, is fairly standard but a great addition. This allows you to adjust voice chat volume through a separate dial, which is a bit different than the Arctis Pro Wireless that does it through ChatMix / LiveMix. The GSP 670 is a simpler and more intuitive solution, and allows you to quickly adjust communications volume on the fly.

On the left earcup, you’ll find a switch for Bluetooth pairing as well as the micro USB port for charging. It’s worth mentioning the microphone lacks a separate mute button. In order to mute the mic, you’ll have to flip it up.

Audio and Mic Quality

Now to the important part, how does the GSP 670 sound? For the past three weeks, I’ve been spending all of my gaming time exploring Norvrandt in Final Fantasy XIV‘s latest expansion, Shadowbringers. If you’ve indulged yourself in the MMORPG, you’ll know it offers one of the best soundtracks video games have to offer. The latest expansion has composer Masayoshi Soken taking things to a whole new level with high-energy rock and jazz vibes blended with classical notes. I mean, just do yourself a favor and listen to this track!

Needless to say, I was really excited to see if I’d notice a difference between the audio quality from Sennheiser’s headset to the SteelSeries I’ve been using for over a year. To really put them to the test, I had one ear cup from the GSP 670 over my left ear, and the Arctis Pro Wireless sat over my right ear while I toggled between the two sources from my PC. To put it simply in the most non-technical terms imaginable, the GSP 670 offers a more “full body” listening experience, meaning you’ll hear all the warm deep bass without drowning out the mid-range and high frequencies.

But this comes with a catch. On a PC, you’ll need to install Sennheiser’s Gaming Suite software to unlock the full potential of the headset. Without it, you’re not able to adjust the equalizer settings and out of the box, it’s a flat listening experience. The software also lets you adjust several other things including reverb, the mic, and create profiles that you can easily switch through depending on the type of media you’re enjoying.

There is also a 7.1 setting in the Gaming Suite, but I found the gaming experience to be much better using the standard 2.0. With the 7.1 Surround Sound, certain effects sounded distant, despite them occurring close to the character in the game. While some gamers might not like the idea of installing yet another piece of software that has to run on startup, it’s essential to customizing the sound to your liking.

This is a bit different than the SteelSeries Arctis Pro Wireless, which allows you to adjust the EQ through the base station. No software is necessary to fine tune the audio on the Arctis Pro Wireless. It’s a minor difference, but one worth mentioning, especially for PC gamers. If you’re planning to purchase this headset for the PlayStation 4 or using it as a Bluetooth headset for a mobile device, there’s nothing to worry about. Streaming Spotify from my phone sounds fantastic without the need for adjustments, and PlayStation 4 games were noticeably better compared to the Sony PlayStation Gold Wireless Headset.

As for the mic, the best test was to see if anyone on Discord noticed a difference after listening to me yell and scream for months with the Arctis Pro Wireless. The verdict? The GSP 670 sounded clearer, and even better once I fine tuned the settings through the software. It’s a very good quality mic for a wireless headset and noise cancellation is a necessity, especially if you do voice-activated communications. Sensitivity through Discord was fine, with the mic not picking up any sort of ambient noises, such as a fan in the background.

Battery Life, Range, and Bluetooth

One of my biggest concerns with the Sennheiser GSP 670 was its battery life since the Arctis Pro Wireless has swappable batteries. The GSP 670’s battery life is advertised as 16 hours through the USB dongle connection, or 20 hours over Bluetooth and I was happy to see it delivered on those estimates. It’s unrealistic to believe that will hold up over time as the battery degrades, but it should always be good enough to last a day of gaming so long as I remember to charge it every other evening. Sennheiser does say the USB quick charge allows you to get two hours of wireless usage after only seven minutes of charging, so it’s not the end of the world if you forget to plug in your headset.

But that is one advantage the SteelSeries Arctis Pro Wireless has over the GSP 670. The Arctis Pro Wireless comes with a base station and two batteries, which means you’ll always have one battery charging (or fully charged) while the other is in use. It’s a bit of a luxury being able to quickly swap your batteries when your headset dies and you never have to remember to plug it in every night, or every other night depending on how much you use the headset. I imagine this probably isn’t much of a concern to the average user, but it is something I’ve grown accustomed to over the years by using swappable batteries from SteelSeries.

As for its range, the layout of my house doesn’t allow me to really test its limits. There is a bit of breakup on the audio if I stray too far, but I haven’t experienced any complete disconnects from the headset, even if I wander downstairs to raid the fridge in the middle of a late night gaming session. It’s comparable to the Arctis Pro Wireless and better than other Logitech wireless headsets I’ve used in the past.

The GSP 670 also allows for Bluetooth connectivity, just like the Arctis Pro Wireless. This allows you to connect the headset to your phone in addition to your PC or PlayStation 4, allowing you to conveniently pick up a phone call through your headset while gaming. The GSP 670 treats this a bit differently than the Arctis Pro Wireless, as it fully switches from one source to another. For example, if you’re gaming and you get a phone call, it’ll disconnect the audio from your PC or PlayStation 4 and only source the audio from your phone. The Arctis Pro Wireless, for better or worse, passes audio from both sources at the same time; you can hear your Discord chat in the background while talking on the phone. It makes more sense to disconnect your gaming audio when you’re taking a phone call, but this ultimately comes down to personal preference and is worth noting if you’re comparing the two headsets.

Closing Thoughts

The high-end wireless headset gaming market doesn’t have a ton of competition, but when you’re spending $300 or more on a headset, you want to make sure you’re getting the right one for you. If all you care about is audio and communications quality, the Sennheiser GSP 670 is the one to get. This is assuming you have no issues with installing additional software on your computer to fine tune the settings to get the best listening experience.

If you’re shopping for a headset for the PlayStation 4 and have no issues paying $350, this is as good as it gets for wireless. The SteelSeries Arctis Pro Wireless has the advantage of swappable batteries and controls on a base station, but the GSP 670 edges it out in audio and microphone quality.

The other popular high-end option is the Astro A50, but a new model is coming to market soon. Its MSRP is $299.99, which is less than both the Sennheiser GSP 670 and the SteelSeries Arctis Pro Wireless. Unfortunately we’ll have to wait to see how it competes. For now, the GSP 670 has replaced the SteelSeries Arctis Pro Wireless as my primary PC gaming headset, although I do wish it had swappable batteries. Are you listening Sennheiser? Imagine how many batteries you could sell!
