Detachable earhook design

Support extends to MMCX/0.78mm 2-pin

The UTWS1 is available with either 0.78mm 2-pin or extended MMCX connectors (more reliable and easier to connect to more earphones compared to standard MMCX), allowing a greater variety of earphones to be given new life as true wireless buds.

*MMCX edition will be released first, 0.78mm 2-pin edition will be released in the future.

New QCC series chip supporting Bluetooth 5.0

The new Qualcomm QCC3020 chip supporting Bluetooth 5.0 is designed with ultra efficiency in mind, being able to transmit data at high speeds stably by effectively shielding from interference while using extremely low power. This reliable Bluetooth connection allows you to enjoy true wireless freedom no matter the situation – whether you are answering a call, listening to exercise, or doing an intense workout.

QCC intelligent noise cancellation
Clarity for both ears

An advanced DSP combined with high-sensitivity microphones in both the left and right units allow for crystal-clear calls even in noisy situations.

aptX/AAC/SBC Bluetooth format support

Apple iOS devices support the excellent-sounding AAC format, while Android devices also support the even higher quality, high-definition aptX format. Support for these formats allow the UTWS1 to give you truly high-fidelity music no matter where you go.

A pleasant surprise every time

FiiO’s extensively experienced engineers have tuned the Qualcomm QCC3020 for maximum audio quality –the signal-to-noise ratio noise floor, and the output LRC circuit has been improved over the reference design, so you can enjoy superior sound quality whether listening to music or taking phone calls.

Custom FPC Bluetooth antenna

To get the best possible performance in the UTWS1 housing, a custom FPC Bluetooth antenna is used. The custom FPC antenna allows for better signal reception than a traditional one, ensuring more stable calls and music.

Don't stop the music with long battery life

Always have your music on you with great battery life.

180 hours standby time | 8 hours of continuous music playback

One song, two listeners
Individual/Binaural listening modes

  • Individual listening mode is like using two separate Bluetooth headsets
  • Binaural mode for traditional and more immersive 2-channel sound

Controls to make life pleasant

We paid special attention to the main singular button on the UTWS1 used to control many functions. With its aluminum alloy material, anodized and sandblasted for greater durability and done in a shiny finish, this tactile button will allow you to easily do the following.

No fear of sweat with waterproof nano coating

The waterproof nano coating protects the UTWS1 inside and out from sweat or water in general.

Custom IEM-like comfort from titanium memory wire

The earhook memory wire made from high-strength titanium is not only extremely durable, but also fits exactly to the shape of your ear for comfortable all-day wear.

True freedom wherever you go

No matter if you’re relaxing, on your commute, driving, or working out, the UTWS1 provides soothing music without the burden of cables.

A case that does it all

In order to protect your UTWS1 and the earphones they are connected to, FiiO has included a specially-designed carrying case. Not only does this case protect your units, it also makes charging the UTWS1 convenient wherever you go by including a separate compartment to store the charging cable.
