The EPOS GTW 270 Hybrid Truly Wireless are truly wireless headphones with a USB-C dongle for low-latency audio for on-the-go gaming. They're a good match for casual use thanks to their sturdy construction, comfortable, stable fit, and well-balanced sound profile, which you can customize extensively in their companion software. They're also easy to transport and do an alright job of blocking out ambient noise.

Our Verdict

6.5 Neutral Sound

The EPOS GTW 270 are okay for neutral sound. They have a fairly well-balanced default sound profile, with a touch of added bass that emphasizes the boom and punch of EDM and hip-hop music, but without overwhelming more delicate vocals or lead instrumentals. If that's not to your liking, their companion software features a couple of different EQ presets as well as a nine-band graphic EQ. Unfortunately, like most in-ears, they have a very compact, unnatural soundstage.

  • Companion software features an EQ and audio presets.
  • Small soundstage.
7.4 Commute/Travel

The EPOS GTW 270 are decent for commuting and traveling. They're exceptionally easy to carry around and feel very sturdy. They're also quite comfortable and won't fall out of your ears while you're on the move. Their latency on mobile devices, particularly those running on Android, is also low, which is good if you plan on watching videos on your way into the office. However, they have a fairly short continuous battery life, which could be annoying during longer commutes, and they don't have any on-board volume controls. While their overall noise isolation capability is alright, they can struggle to filter out the low rumble of bus or plane engines.

  • Comfortable, stable fit.
  • Low latency on mobile devices over Bluetooth.
  • Impressive build quality.
  • Limited control scheme.
  • No power-saving features.
8.0 Sports/Fitness

The EPOS GTW 270 are a great option for sports and fitness. They're stable, feel solid enough to deal with a couple of drops and bumps, and allow your ears to breathe while using them. They're also rated IPX5 for water protection, though we don't currently test for this. Unfortunately, they lack any sort of onboard volume controls, so you may need to pull your phone out to make an adjustment, which could throw off your rhythm.

  • Comfortable, stable fit.
  • Impressive build quality.
  • Limited control scheme.
7.0 Office

The EPOS GTW 270 are an alright choice for office use. They do a good job of filtering out background chatter and leak very little audio, which means you can listen to content at high volumes without worrying about annoying people nearby. That said, their short continuous battery life may require you to put them back in their case to occasionally recharge, and they lack any sort of power-saving measures like an auto-off timer.

  • Comfortable, stable fit.
  • Very little audio leakage.
  • Limited control scheme.
  • No power-saving features.
6.7 Wireless Gaming

The EPOS GTW 270 are fair for wireless gaming. Their USB dongle has somewhat low latency and supports audio and visual transmission, which is nice if you want to game with others. They're a decent fit for wireless gaming thanks to their comfortable fit and well-balanced sound profile that can be adjusted via their companion software, though they do have short continuous battery life. Their Dolby 7.1 virtual surround sound feature will provide a more immersive listening experience.

  • Companion software features an EQ and audio presets.
  • Sub-par mic noise handling capability.
5.5 Wired Gaming

The EPOS GTW 270 are wireless-only headphones and can't be used on a wired connection.

6.8 Phone Calls

The EPOS GTW 270 are a fair choice for making phone calls. Their mic makes your voice sound fairly clear and natural, but a little thin. It can struggle with isolating your voice from loud background noise. The buds themselves do an okay job of blocking out ambient noise, though you may have trouble hearing what's being said if you're in a loud environment, like a bus or a subway train.

  • Good mic recording quality.
  • Sub-par mic noise handling capability.
  • 6.5 Neutral Sound
  • 7.4 Commute/Travel
  • 8.0 Sports/Fitness
  • 7.0 Office
  • 6.7 Wireless Gaming

Differences Between Sizes And Variants

The EPOS GTW 270 Hybrid only come in one color variant: 'Black/Grey', and you can see their label here.

If you come across a different variant, let us know in the discussions, and we'll update our review.

Compared To Other Headphones

The EPOS GTW 270 are truly wireless headphones that the manufacturer advertises as being designed for on-the-go gaming. Unlike the Razer Hammerhead True Wireless, they come with a separate dongle that allows for somewhat low audio latency.

If you're looking for casual-use alternatives, take a look at our list of the best truly wireless earbuds and the best wireless Bluetooth earbuds. If you're looking for gaming-oriented wireless options, see our picks for the best wireless gaming headsets.

Razer Hammerhead Pro HyperSpeed True Wireless

The Razer Hammerhead Pro HyperSpeed True Wireless have the edge over the EPOS GTW 270 Hybrid Truly Wireless when it comes to gaming. The Razer have a more neutral default sound profile, which some users may prefer, and noise cancelling, so they can block out a very good amount of background noise. Their overall mic performance is better, too, and so is their battery life. However, the EPOS are more comfortable and better built. They also support multi-device pairing, which is handy to stay connected to two devices simultaneously.

Razer Hammerhead True Wireless Pro

The EPOS GTW 270 Hybrid Truly Wireless are more versatile than the Razer Hammerhead True Wireless Pro. The EPOS are comfier, better-built, and block out more ambient noise. They also come with a separate dongle that allows for low-latency audio. Meanwhile, the Razer support control remapping, and are fitted with a standby mode to conserve battery life. They also last longer on a single charge and have a more neutral sound profile, which some users may prefer. 

Sony INZONE Buds Truly Wireless

The Sony INZONE Buds Truly Wireless are better for most uses than the EPOS GTW 270 Hybrid Truly Wireless. The EPOS are more comfortable, better built, and support multi-device pairing through Bluetooth and their wireless dongle. However, the Sony have a more neutral sound profile overall, and their battery life performance is significantly better. There have also been reports about users encountering issues with the EPOS' dongle connectivity after updating to the latest firmware.

Sony PULSE Explore Truly Wireless

The EPOS GTW 270 Hybrid Truly Wireless are better gaming earbuds than the Sony PULSE Explore Truly Wireless. The EPOS feel sturdier, have a better passive noise isolation performance, and offer a much better mic recording quality. They have a dedicated companion app with sound customization features and support multi-device pairing via Bluetooth or via both Bluetooth and non-Bluetooth wireless. However, you might prefer the Sony PULSE because they have lower latency over non-Bluetooth wireless. The Sony also work with PlayStation Portal, a remote player for the PlayStation that doesn't support Bluetooth or have a USB port.

Jabra Elite 85t Truly Wireless

The Jabra Elite 85t Truly Wireless and EPOS GTW 270 Hybrid Truly Wireless each have their own advantages, and you may prefer one over the other depending on your needs. The Jabra have a far more comprehensive control scheme, a better noise isolation performance courtesy of their ANC feature, longer battery life, an auto-off timer, and a companion app that offers a broader range of customizability. Meanwhile, the EPOS come with a dongle that allows for somewhat low-latency audio transmission, offer better overall mic performance, and have a Dolby 7.1 virtual surround sound feature. 

Apple AirPods Pro Truly Wireless

The Apple AirPods Pro Truly Wireless are more versatile than the EPOS GTW 270 Hybrid Truly Wireless. The Apple headphones have a noise-canceling feature that blocks out significantly more background noise. They also have a longer total battery life, courtesy of a charging case that supplies roughly five additional charges. However, the EPOS have a broader range of customization features. Their mic also offers superior recording quality and noise-handling capability.

Samsung Galaxy Buds+ Truly Wireless

The Samsung Galaxy Buds+ Truly Wireless re slightly better for casual use than the EPOS GTW 270 Hybrid Truly Wireless. The Samsung have a more stable fit, a more comprehensive control scheme, a very well-balanced sound profile, and significantly longer 13-hour-plus battery life. Conversely, the EPOS are better-built, offer a somewhat better mic performance, and leak less audio. Their companion software also features a graphic EQ.

SteelSeries TUSQ

The EPOS GTW 270 Hybrid Truly Wireless and the SteelSeries TUSQ have different strengths, and you may prefer either one. The EPOS are wireless gaming headphones that support Bluetooth. Their USB-C dongle offers fairly low latency. They feel better built, have a more comfortable fit, their sound profile is more neutral, which some users may prefer, and they support Dolby 7.1. They're also able to block out more background sound, and their companion app offers a graphic EQ and presets to help you customize their sound to your liking. In contrast, the SteelSeries are wired gaming headphones, ensuring virtually no latency, and they have a detachable boom mic that offers a significantly better overall performance.

The EPOS GTW 270 Hybrid are comfortable. They sit in your ear without causing too much discomfort, and similarly to the Sony INZONE Buds Truly Wireless, they don't have an especially deep fit. Using the controls on the left bud also doesn't force it any deeper into your ear canal, which is good. That said, they're a bit bulky for true wireless headphones and stick out of your ears a little.

The EPOS GTW 270 Hybrid have a limited control scheme. All functions are controlled via a physical button on the left bud. One click pauses and plays media as well as answers and ends calls. Two clicks skips a track forward and three clicks skips media backward. A two-second hold turns on your phone's voice assistant. The button itself offers good physical feedback, but using just the right bud corresponds to a total lack of controls. There's also no onboard volume control. If you're looking for gaming earbuds, check out the Logitech G333, which are wired gaming headphones that offer in-line volume control.

The EPOS GTW 270 Hybrid have a great charging case. It's made of anodized aluminum and doesn't take up all that much room. There are five LED lights on the case that roughly indicate remaining battery life, as well as a dedicated Bluetooth pairing button, which only works when the buds are placed in their cradles.

Build Quality

The EPOS GTW 270 Hybrid are very well-built. They feel more durable than the SteelSeries TUSQ as they're made of premium-feeling high-grade plastic. Overall, they feel as though they can survive a couple of drops and bumps. The removable ear tips also feel quite sturdy and won't tear too easily. The buds themselves are rated IPX5 for water resistance.


The EPOS GTW 270 Hybrid are stable in-ear headphones. They won't fall out of your ears even during workouts, though they'd do an even better job of staying in place if they had stability fins. Since they stick some way out of your ears, they could also get caught on something close to your head.

Sound Profile
Bass Amount
1.76 dB
Treble Amount
-2.85 dB

Using firmware update 9.2.4, the EPOS GTW 270 Hybrid have a bass-heavy and boomy sound profile. Their overemphasized bass response will suit genres like EDM or hip-hop and emphasize in-game sound effects without overwhelming vocals or instruments, thanks to their flat and even mid-range. Unfortunately, their uneven treble range results in a loss of clarity in more delicate genres and generates a somewhat dark and veiled sound. If that's not to your liking, their companion app features a nine-band graphic EQ and four EQ presets.

Unfortunately, there's some mismatch present between the L/R drivers. Even after different reseats, the mismatch is still present. Luckily, it's very minor.

Frequency Response Consistency

The frequency response consistency is superb. As long as you achieve a tight fit with the included ear tips, audio will be delivered consistently on separate listening sessions.

The EPOS GTW 270 Hybrid have good bass accuracy. They provide adequate thump and rumble thanks to their relatively well-balanced low-bass. However, they have a bump in the mid to high-bass, which adds intense punch and boom to mixes. It can help bring out sound effects like footsteps in gameplay, but it also bloats and muddies dialogue and instruments.

Mid Accuracy

The EPOS GTW 270 Hybrid have great mid accuracy. The bump from the high-bass carries over into the low-mid and clutters some vocals and lead instruments. That said, the mid and high-mid ranges are both flat and even, so dialogue and instruments sound detailed, present, and clear in your tracks.

Treble Accuracy

6.09 dB
-6.34 dB
0.68 dB
-1.22 dB

The EPOS GTW 270 Hybrid have sub-par treble accuracy. The low-treble is very underemphasized, so vocals and lead instruments sound dark and veiled. The uneven mid-treble range can give sibilants like cymbals an alternatively lispy and piercing quality.

2.02 dB
2.09 dB

These in-ears have okay peaks and dips performance. There's some mismatch between the L/R drivers, but it's very minor overall. A bump in the high-bass range adds extra warmth to mixes, though some users may find them to sound slightly muddy and boomy. A recess in the mid-mid pushes vocals and lead instruments to the back of the mix, while a rise in the high-mid makes them sound honky and harsh. A large dip in the low-treble veils the finer details of some upper harmonics, while a rise in the mid-treble can make sibilants sound piercing.

Weighted Group Delay
Weighted Phase Mismatch
Weighted Amplitude Mismatch
Weighted Frequency Mismatch

The EPOS GTW 270 Hybrid have a very good imaging performance. Their weighted group delay falls well beneath the audibility threshold, resulting in tight bass and transparent treble. The L/R drivers are also very well-matched in frequency and phase response, so objects like voices and footsteps will be accurately placed within the stereo image. Although there's a peak in the phase response's mid-mid, it's very hard to hear, even with real-life content. However, there's some amplitude mismatch present, so there may be a noticeable difference in levels between the drivers.

Passive Soundstage
PRTF Accuracy (Std. Dev.)

The EPOS GTW 270 Hybrid have a terrible passive soundstage, which is quite normal for closed-back in-ear headphones. Creating an out-of-head-like listening experience relies on interaction with the outer ear, which in-ears like the EPOS bypass. Therefore, sound is perceived as coming from inside your head rather than all around you.

WHD @ 100

The EPOS GTW 270 Hybrid have an okay weighted harmonic distortion performance. There's some distortion in the lower treble range at both moderate and high listening volumes, but this may not be noticeable to all listeners. The rest of the range falls within acceptable limits, so audio reproduction will be fairly clean and pure.

The EPOS GTW 270 Hybrid do a decent job filtering out ambient noise. While they don't block out a lot of low-pitched background noise, like the rumble of bus or plane engines, they perform better in regards to filtering out ambient chatter from people nearby. They also do an excellent job of filtering out higher-pitched background noise, like the hum of an AC unit.

The integrated mic does a sub-par job of separating speech from background noise. Using the USB dongle results in a worse noise handling performance than via Bluetooth. There's distortion present as the mic attempts to block out noise, and the volume of your voice diminishes when there are loud sounds. As a result, if you need to use the mic, it's best to be in a quiet environment to ensure that you're heard clearly. If you want to fine-tune the mic's performance, the companion app offers handy features like noise gate, sidetone, and gain.

The EPOS GTW 270 Hybrid's battery performance is poor. If you've updated your headphones to firmware 9.2.4, you're likely disappointed by the low continuous battery life, especially since the manufacturer advertises them to last five hours continuously. You're not alone. Our retest achieved over three hours of playback time, which is a big step down from our original results of over five hours. Unfortunately, this really lowers their total battery life, and even with three additional charges in the case. They also lack power-saving measures, like a standby mode or an auto-off timer. They advertise a quick-charge feature allowing one hour of playback time on a 15-minute charge. If you're looking for gaming earbuds with a better battery performance, try the Razer Hammerhead Pro HyperSpeed True Wireless instead.

The EPOS GTW 270 Hybrid have decent non-Bluetooth wireless latency. These headphones come with a USB-C dongle that uses aptX-LL codec. This codec ensures somewhat low latency. It falls just outside of good limits, but it won't be too noticeable. If you're concerned about it, the Sony PULSE Explore Truly Wireless have less latency with their dongle. Also, unfortunately, there have been user reports that firmware update 9.2.4 has caused issues with dongle connectivity. While we didn't encounter these issues, if you have, please let us know in the discussions, and we'll update our review.
