The EPOS GTW 270 Hybrid Truly Wireless are truly wireless headphones that come with a USB-C dongle for low-latency audio. While they're advertised as being designed for on-the-go gaming, you can't use their mic while using their dongle, which is a somewhat significant drawback. That said, they're a good match for casual use thanks to their sturdy construction, comfortable, stable fit, and well-balanced sound profile, which can be customized extensively in their companion software. They're also easy to transport and do an alright job of blocking out ambient noise.

Our Verdict

7.2 Mixed Usage

The EPOS GTW 270 are decent for mixed usage. Their compact design, breathable, stable fit, and sturdy build quality make them a good match for on-the-go use. Their sound profile is mostly well-balanced and can be customized extensively, though they don't provide an especially spacious or natural listening experience. While they can be used for single-player gaming, their short battery life is a bit of an annoyance. Their integrated mic transmits your voice clearly, though people on the other end of the line may struggle to understand you in loud environments.

Pros
  • Comfortable, stable fit.
  • Impressive build quality.
  • USB-C dongle allows for low-latency audio playback.
Cons
  • Limited control scheme.
  • No power-saving features.
  • No mic usage with USB-C dongle.
6.6 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.

Pros
  • Companion software features an EQ and audio presets.
Cons
  • Small soundstage.
7.5 Commute/Travel

The EPOS GTW 270 are good for commuting and traveling. They're exceptionally easy to carry around and feel very sturdy. They're also quite comfortable, and shouldn't fall out of your ears while you're on the move. Their latency on mobile devices, particularly those running on Android, is also quite 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.

Pros
  • Comfortable, stable fit.
  • Low latency on mobile devices over Bluetooth.
  • Impressive build quality.
Cons
  • 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.

Pros
  • Comfortable, stable fit.
  • Impressive build quality.
Cons
  • Limited control scheme.
6.9 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.

Pros
  • Comfortable, stable fit.
  • USB-C dongle allows for low-latency audio playback.
  • Very little audio leakage.
Cons
  • Limited control scheme.
  • No power-saving features.
  • No mic usage with USB-C dongle.
7.1 Wireless Gaming

The EPOS GTW 270 are suitable for wireless gaming as long as you don't mind the lack of mic compatibility via their USB-C dongle, though they offer full compatibility with devices that support the aptX-LL codec. Otherwise, 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 should also provide a more immersive listening experience, though we don't currently test this function.

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.

Pros
  • Decent mic recording quality.
Cons
  • Mediocre mic noise handling capability.
  • 7.2 Mixed Usage
  • 6.6 Neutral Sound
  • 7.5 Commute/Travel
  • 8.0 Sports/Fitness
  • 6.9 Office
  • 7.1 Wireless Gaming

The EPOS GTW 270 have a fairly premium appearance. The buds' enclosure has a fairly distinctive and slightly squared-off shape, and the manufacturer's logo is plainly visible on the outer surface of the buds.

The EPOS GTW 270 Hybrid are comfortable. They sit in your ear without causing too much discomfort and 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 they stick out of your ears a little.

Additional Controls Voice Assistant

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.

Like most in-ears, the EPOS GTW 270 are very breathable. Your ears should be able to breathe freely while wearing them, and you shouldn't sweat any more than usual.

The EPOS GTW 270 Hybrid have a great charging case. It's made of dense high-grade plastic 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're made of premium-feeling high-grade plastic and feel as though they should survive a couple of drops and bumps. The removable ear tips also feel quite sturdy and shouldn't tear too easily. The buds themselves are rated IPX5 for water resistance, though we don't currently test for this.

Design
Stability

The EPOS GTW 270 Hybrid are stable in-ears. They shouldn'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.

The EPOS GTW 270 Hybrid have a slightly bass-heavy sound profile. Their overemphasized bass response should 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 as well as four EQ presets.

The EPOS GTW 270 Hybrid have great bass accuracy. They provide adequate thump and rumble thanks to their relatively well-balanced low and mid-bass ranges. The bump in the high-bass range adds a bit of extra warmth and boom, but also slightly muddies some mixes.

The EPOS GTW 270 Hybrid have excellent mid accuracy. The bump from the high-bass carries over into the low-mids and slightly clutters some vocals and lead instruments. There's also a small dip that nudges vocals and lead instruments toward the back of the mix, though the even high-mid range helps keep these notes are detailed and clear without being harsh.

The EPOS GTW 270 Hybrid have poor treble accuracy. Most of the range is 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.

These in-ears have okay peaks and dips performance. A slight 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-mids pushes vocals and lead instruments to the back of the mix while a rise in the high-mids 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.

The EPOS GTW 270 Hybrid offer fantastic stereo 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 regards to amplitude, frequency, and phase response, so objects like voices and footsteps should be accurately placed within the stereo image without any apparent holes. That said, these results are only valid for our test unit, and yours may perform differently.

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.

The EPOS GTW 270 Hybrid have decent 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 should be fairly clean and pure.

The EPOS GTW 270 Hybrid do an alright job of filtering out ambient noise. While they don't block out much in the way 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 passable job of separating speech from background noise. People on the other end of the line may have trouble understanding you if you make a call from a noisy or crowded environment, like a subway station, so they're best suited for communicating in quieter settings.

The EPOS GTW 270 Hybrid's battery performance is sub-par. While their battery life of over five and a half hours outlasts their advertised claim of just five hours, they lack any sort of power-saving measures, like a standby mode or an auto-off timer. They advertise a quick-charge feature that allows for one hour of playback time on a 15-minute charge, but we don't currently test for this. Their case supplies enough charge for just under 23 hours of total playback time, which should be enough for a couple of days. Of course, it's worth noting that battery life can vary with real-world usage.

The EPOS GTW 270 have decent Bluetooth connectivity. They support Bluetooth 5.1, but you can't pair them with more than one device at a time. They don't support NFC pairing either. Out-of-the-box, they offer low latency on mobile iOS and Android devices. While their latency on PC with the SBC codec is quite high, they support the aptX-LL codec, which can drastically reduce latency on compatible devices, making them a good fit for streaming video. However, it's worth noting that different apps and devices compensate for latency to varying degrees, so your experience may vary in real-world conditions.

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 so we can update our review.

Compared To Other Headphones

The EPOS GTW 270 are truly wireless headphones that are advertised as being designed for on-the-go gaming. Unlike the Razer Hammerhead True Wireless, they come with a separate dongle that allows for low-latency audio, though it doesn't provide mic compatibility with PCs, PS4/PS5 consoles, or Nintendo Switch consoles. 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 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, though you can't use their mic with it. Meanwhile, the Razer offer superior overall mic performance, support control remapping, and are fitted with a standby mode to conserve battery life, though they don't last as long as the EPOS on a single charge.

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, superior noise isolation capability 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 low-latency audio transmission, offer better overall mic performance, and have a Dolby 7.1 virtual surround sound feature, though we don't currently test that function.

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 enables them to block out significantly more background noise. They also have a more stable fit and 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 and offer lower latency on most devices over Bluetooth. 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.
