EPOS Sennheiser GSP 600 Headphones Review

The EPOS 600 are gaming-oriented headphones with a simple design. They're mostly made of black plastic with red accents on the ear cups. The boom microphone is flippable, but unfortunately, you can't remove it for a more casual look.

These headphones are comfortable. You can adjust the clamping force by sliding the handles on each side until you get a comfortable fit. When both of the sliders are all the way up, the clamping force is 1.4 lbs, and when both of the sliders are all the way down, the clamping force is 1.1 lbs. You can also adjust the hinges to accommodate wider head shapes. There's even lots of padding on the headband and the ear cups, although the bulky design may not be comfortable for all users.

These headphones have a limited set of controls. There's a volume wheel on the right ear cup that stops when you reach min/max volume, and you can mute the microphone by flipping the boom mic into an upright position. Unfortunately, there aren't any call or music controls on the headphones, which can be limiting.

The EPOS 600 aren't very portable. They have a bulky design, and you can't even fold them into a more compact format. As a result, they may not fit very easily into your bag. They don't have a carrying case for on-the-go protection, either. However, this shouldn't be an issue for users who plan to use them with their home gaming setup.

The EPOS 600 have a great build quality. They're mostly made of plastic, which feels quite solid and durable. The headband padding is a soft fabric. There's faux leather on the edges of the ear cup and a silicone-like fabric inside the cups. Overall, these headphones seem sturdy, though the cable could be a possible weak point.

The EPOS 600 are decently stable. At their maximum clamping force, they should stay on your head during casual gaming sessions. However, they aren't designed for higher-intensity movements, and they may fall off if you shake your head vigorously.

The EPOS GSP 600 have a fairly neutral sound profile. Thanks to their balanced mid and treble ranges, they reproduce vocals and lead instruments clearly and accurately. However, they lack some bass, so you don't feel some of the deep thump and rumble in action-packed games. Unfortunately, they don't offer any sound customization features.

The EPOS 600 have poor frequency response consistency. Like many gaming headphones, they have inconsistent bass and treble delivery depending on their fit, seal, and positioning on your head. You may perceive their bass response differently if you have thick hair or wear glasses.

The EPOS 600 have decent bass accuracy. The entire range is even; however, it's underemphasized, so you don't really feel the punch or thump in your audio. Bass delivery can vary depending on their fit and positioning on your head, so this represents the average results. Your real-world experience may vary.

These headphones have fantastic mid accuracy. The entire range is neutral and balanced, so vocals and lead instruments are clear, present, and detailed.

These headphones have great treble accuracy. The range is pretty balanced, so vocals and lead instruments are detailed and present. Sibilants like S and T sounds can be alternately piercing or dull.

These headphones have good peaks and dips performance. The slight dip in the high-bass represents a lack of warmth in the mix, while the peak in the low-mids can muddy vocals and lead instruments. The uneven low and mid-treble ranges can make vocals, lead instruments, and sibilants alternatively harsh and dull.

The EPOS Sennheiser GSP 600 have a great imaging performance. While they have a slightly loose bass reproduction, it shouldn't be too noticeable. The rest of their weighted group delay falls within good limits, resulting in a transparent treble. Also, the L/R drivers of our test unit are well-matched in phase and amplitude, which helps to accurately localize sound objects like voices and video game effects in the stereo field. There's some frequency mismatch, though, so there may be holes in the stereo image. That said, it's very slight, so you may not hear it with regular content. Also, these results are only valid for our test unit, so your real-world experience may vary.

The EPOS Sennheiser GSP 600 have a poor passive soundstage performance. Their soundstage is perceived to be small, and audio seems like it's coming from inside your head rather than from speakers placed all around you. Also, it doesn't seem as open or as spacious as soundstages from open-back headphones.

The EPOS Sennheiser GSP 600 have a satisfactory weighted harmonic distortion performance. While there are some slight peaks in the bass range at moderate listening volumes, the rest of the range falls within good limits, so audio reproduction is clean and pure.

These are the settings we used to test these headphones. Our results are only valid when using these settings.

The EPOS GSP 600 have mediocre noise isolation. Like many gaming headphones, they struggle to block out bass-heavy background noises like bus and plane engines. However, they can block out mid-range noise like people chatting around you and higher-frequency sounds like the hum from AC units.

The EPOS GSP 600 have a very good leakage performance. If you're listening to audio at loud volumes, there may be a bit of leakage in the mid range. However, it shouldn't be too noticeable under the noise floor of an average office.

The microphone has an impressive recording quality. Your voice is full-bodied, natural, and easy to understand.

The mic has good noise handling capabilities. It can separate your voice from background noises, so whoever's on the other end of the line can understand you even if you're gaming in a noisy setting.

The EPOS GSP 600 come with a 1/8" TRRS cable for audio and microphone compatibility. There's also a Y-splitter to 1/8" TRRS cable included, and it's 2.5m long. It's useful for systems that have separate audio and mic jacks.
