Styling and comfort
Although the design is largely the same, I feel the GSP 670 has a more stylish appearance than the GSP 370. It has a couple of arms that attach the earcups to the headset giving the headset a more industrial, metal girder look. The earcups themselves are quite large and surround the ears, giving the headset a somewhat bulky look, which is further enhanced by the attached swivel mic.
But the chunky look befits the sturdy construction of the GSP 670. Although, it is primarily plastic, it is a thicker material that seems like it can take a bit of a beating. The headband does not appear like it is fitted with enough padding, but upon wearing the headset, I was pleasantly surprised to find that the headband was comfortable even after a lengthy gaming session. I must admit that at first, the headset did feel quite tight, but the headband has a couple of sliders which distribute the pressure, allowing customization for each person. After adjusting the sliders to suit, I found that I have no further trouble. And this was despite the headset being quite on the heavy side. It can also fit a range of head sizes, with it comfortably fitting my eight-year old's smaller head.
The earcups have a leather outer but have felt on the external section that sits around the ears. A memory foam inside means that the ear cups sit nicely around the ears, even for someone - like me - who wears glasses. Fitting snugly around the ears, the earcups block out a substantial amount of external noise, whilst the felt seems to prevent a sweat build-up that gamers can often occur when wearing for a lengthy period.
All the controls are included in the headset, which probably accounts for some of the bulk in size and weight. The left side includes the charging port as well as the pairing switch, whilst the right earcup contains a couple of volume controls, the main control being a rigid dial that continues the sturdy vibe of the headset.
Features and Performance
It is all well and good to have a comfortable headset, but it needs to perform. And the GSP 670 has several features that set it apart from other gaming headsets. The wireless functionality is always a plus, enabling gamers to be untethered from their PC. Of course, the USB dongle does take up a valuable USB port though - something that a 3.5mm plug doesn't do.
The good news about the USB transmitter is that the headset can also be paired to a phone or tablet using the Bluetooth connectivity. This enables the GSP 670 to be more or an all-rounder as you can use it on the go. I was using the headset for work as well - particularly important for COVID isolation - connecting with colleagues via Microsoft Teams calls. One particular feature that I enjoyed was the fact that I could seamlessly switch between watching a video on my PC and then answering a call on my phone. Having the headset paired to both the USB dongle and the phone allows for greater productivity and reduces the need for separate headsets.
But although the headset can be great for the work environment, it is the gaming space that we're interested in, and for that, the GSP 670 works particularly well. The swivel mic on the left ear cup automatically switches on once it is lowered into place and can be just as quickly muted but swinging it back up - a handy function. The microphone captures clear voices, and simultaneously seems to block out other noises that would ordinarily be captured, which is great when you have kids yelling in the background during an extended gaming session. OK, they were my kids and they were asking me what was for dinner, but I digress. The audio of the 7.1 Surround Sound headset is amazing. The directional sound enables gamers to pinpoint where sound is coming from, whether it is someone sneaking up from behind you on a gravel road, or a bird chirping in the distance. And when putting a goal in the back of the net in FIFA, it feels like you're surrounded by the cheering crowd.
One let down of the GSP 670 is the bass. It doesn't have the same deep bass sound of other headsets which may annoy some music lovers. Some tinkering inside the Sennheiser Gaming Suite software does improve things a tad, but still doesn't produce the same deep tones and explosions.
The GSP 670 has a battery life of around 20 hours, which means you'll get a day of work and gaming out of them before needing to recharge. It could mean that you could run out of battery mid game though and that could be annoying. Fortunately, the charging cable - which charges up the headset in around half an hour - allows the headset to be used while charging.
The GSP 670 is a wonderful headset that performs superbly whether you're seated in front of a PC, or on the move thanks to the Bluetooth connectivity. It is a styling looking headset which is only let down by the permanently attached swivel mic that looks like a periscope when not in use. The 7.1 surround sound provides crisp clean audio, whilst the microphone is up there with the best I have reviewed. The Sennheiser Gaming Suite allows gamers to check the charge levels as well as customize various aspects of the audio. The ability to charge and continue when attached with the charging cable is an added bonus. If you're looking for a high-end headset, which can be used in a variety of scenarios, then definitely give the EPOS Sennheiser GSP 670 Wireless Gaming Headset a look.
