REVIEW – In May 2021 I reviewed the EPOS GTW 270 Hybrid Wireless Earbuds, and overall, I was quite impressed.  However, I thought they lacked two critical features.  EPOS recently updated these earbuds, but did they add the critical features I thought were missing?  Read on to find out!

What is it?

The EPOS GTW 270 Hybrid Closed Acoustic Wireless Earbuds with Dongle are a true wireless earbud audio system that operates with a hybrid connection via both Bluetooth and USB-C dongle.

What’s in the box?

Design and features

EPOSGTW270Hybrid 06

The look and feel of the EPOS GTW 270 Hybrid earbuds, dongle, and charging case hardware is unchanged from the original version, as you can see in these pics.  They still have that high-end design and construction, with their sleek, low-profile style.

EPOSGTW270Hybrid 08

The earbuds retain their characteristic two-tone color scheme: black body with satin-finished metallic accents and the stylized EPOS “E” logo printed at the center.

EPOSGTW270Hybrid 09

The look is very minimalist, with an understated futuristic “tech” appearance.

EPOSGTW270Hybrid 10

The EPOS GTW 270 Hybrid earbuds have several small gold metallic dots that are a combination of contact points and magnets that facilitate secure charging of the earbuds when they are placed inside the charging case.

EPOSGTW270Hybrid 11

The charging case is made from aluminum with a matte, anodized gray finish.  The case’s design gives it a nice visual appearance and tactile feel, with rounded corners and edges as well as its satiny, matte finish.  This might just be the most durable earbuds case I’ve ever used.  I’ve dropped it on hard floors and even concrete and the most wear it’s shown is a few small scratches on one corner.  The front of the case also has five tiny LEDs and an oval-shaped button—more on these below.

The interior of the case has a soft, rubber-type coating that acts as a shock absorber, helping to protect the earbuds should you drop them while they are inside the case.  The case’s lid has a slight spring assist that makes it snap open and closed, which feels satisfying and secure.  When inside the case, each earbud has a tiny LED that glows green to indicate that they are at full charge, yellow to indicate a partial charge, and red to indicate that the earbuds’ batteries are nearly fully drained.

EPOSGTW270Hybrid 14

The EPOS GTW 270 Hybrid earbud’s charging case has two cavities that perfectly fit each earbud.  As seen in the above image, five spring-loaded gold pins act as contacts, charging the earbuds while they sit snug and secure inside the charging case.  There are also two larger gold circles which I believe are tiny magnets that help align and orient the earbuds to the correct position for charging them.

EPOSGTW270Hybrid 15

The EPOS stylized “E” logo is printed atop the case.  On the rear of the case is a USB-C port for charging the case itself with the included USB-C cable.

EPOSGTW270Hybrid 16

When the case is charging, the tiny blue LEDs on the front of the case illuminate to indicate the current charge level.  When the case is not charging, you can press the oval-shaped button on the front of the case to display the current charge level of the case, a feature I find to be quite handy.

EPOSGTW270Hybrid 19

Also included is a silicone sleeve with an attached lanyard.  The sleeve helps protect the dongle from damage, and the lanyard can be attached to a keychain, carabiner, or another item to help keep the dongle from getting lost.

The sleeve has a small window that allows the dongle’s LED to be seen when in use.

The photo above shows the relative size of the GTW 270 Hybrid earbuds and the dongle.  All components are quite small and compact.


EPOSGTW270Hybrid 07

The EPOS GTW 270 Hybrid earbuds are easy to pair with your phone.  Open the lid of the charging case then press the oval-shaped button on the front of the case.  The LED will begin to flash blue and red.  Go to your phone’s Bluetooth setting and select “EPOS GTW 270” from the list of devices.  On a couple of occasions, I had to re-pair the earbuds.  Just place them back in the case and go through the steps I just described and you should be all set.

EPOSGTW270Hybrid 17

The EPOS GTW 270 are “hybrid” earbuds due to their included wireless dongle.  The dongle plugs into a USB-C port and allows the earbuds to connect to devices like Playstation game consoles, the Nintendo Switch, and PCs.  If a device doesn’t have a USB-C port, the EPOS GTW 270 includes an adapter cable for USB-A ports.  I was hoping that this updated version of the EPOS GTW 270 Hybrid earbuds would have added compatibility with XBox, but I was disappointed to find that it did not.  

EPOSGTW270Hybrid 18

Simply plug the dongle into a USB-C port on your device.  Here, I’m using my work-issued Lenovo X13 laptop.  Once the dongle has been plugged into a USB-C port, open the lid of the earbuds’ charging case and a small LED on the side of the dongle glows blue for a few seconds, then purple to indicate that the dongle and the earbuds are paired.

One of the most significant improvements that EPOS made in this upgraded version of their GTW 270 Hybrid earbuds is that the dongle now allows use of the earbuds’ microphone, something that the previous version could not do.  This allowed me to plug in the dongle and easily use the earbuds for Zoom and MS Teams virtual meetings for work.  This means I can toss the EPOS GTW 270 Hybrid earbuds and their dongle in my travel bag and use them for virtual meetings while on the road.  Kudos, EPOS, this is a big improvement.



EPOSGTW270Hybrid 23

One of the aspects of the EPOS GTW 270 Hybrid earbuds that I like best is how well they fit in my ears.  They fit better than most of the many earbuds I’ve reviewed here at The Gadgeteer.

EPOSGTW270Hybrid 24

Once I switched to the largest size of earbud tips (I have larger than average ear canals), the earbuds fit well in my ears.  Just a light press and a small twist and the earbuds fit snugly but comfortably. Their ergonomic shape, compact size, and lightweight helped them stay put during all sorts of activities, including intense exercise.  In addition, their IPX 5 water resistance kept them fully functioning despite significant amounts of sweat and even in steady rain.

EPOSGTW270Hybrid 25

The earbuds have fairly standard touch controls, such as play/pause, fast-forward, rewind, call answer, call end, and so forth.  The GTW 270 Hybrid earbuds also provide a significant degree of passive noise blocking.  I think this is largely due to how well they fit in my ears.  I was able to hear clearly through them even when mowing and trimming the lawn and vacuuming the house.

This updated version of the EPOS GTW 270 Hybrid earbuds seems to have a sound quality that may be a bit upgraded from the original version.  Between its ability to effectively block ambient noise as well as solid onboard sound hardware creates a great combination of enjoyable listening, from podcasts and audiobooks to music.

What I like

  • Small, compact earbuds that fit in my ear and stay put through all sorts of activities
  • Nearly indestructible aluminum case with power indicator
  • Easy setup through both Bluetooth and dongle
  • The dongle now includes microphone capability—this is a big win

What I’d change

  • Add XB0x compatibility
  • Add on-board volume controls

Final thoughts

I was impressed with this updated version of the EPOS GTW 270 Hybrid earbuds.  When I reviewed the original version, I had mixed feelings about it.  I was impressed with many of its features, but there were a few things I wanted to see added, namely, XBox compatibility, on-board volume controls, and the ability to use the microphone with the dongle.  EPOS did add the ability to use the microphone with the dongle, which is a big win.  However, the earbuds are still not compatible with XBox consoles, nor do they have on-board volume controls, which is still a bit disappointing.  Overall though, I really like the EPOS GTW 270 Hybrid earbuds, and this updated version is even better.
