Perfection, starting from pairing

You'll have a great experience, even starting from the beginning step of pairing. The ear units and the charging case are designed to work together for your convenience – opening the case's lid automatically turns on the ear units, while closing the lid turns them off. Bluetooth pairing and clearing pairing is done with the pairing button of the charging case, greatly simplifying such operations into one button.

With TWS+ dual transmission technology, there is no primary and secondary ear unit on the UTWS3 – both units are primary and directly connected to your Bluetooth device. This means lower latency, stronger resistance against interference, and an overall more stable connection.

Dual direct connections lower latency

Note: TWS+ requires your smartphone's support. Some phones are unsupported or may have compatibility issues.


battery charging case


battery life

For you to get longer battery life, we have included a charging case with the UTWS3. The charging case is large enough to accommodate both the ear units and most earphones at the same time, making it more convenient for charging/pairing/turning on and other situations. The charging case, with its built-in 800mAh battery, provides up to 30 hours of battery life.

Taking wireless

sound to its limits

There is a new wireless option for your existing detachable-cable earphones! The UTWS3, with a choice of 0.78mm 2-pin/MMCX connectors, allows you to transform most detachable earphones into a true wireless pair. Experience high quality sound while being freed from the mess of wires.

More clever features to tap into

Through either the FiiO Control or FiiO Music apps, you can adjust the EQ, channel balance, and other audio options of the UTWS3. There will also be firmware updates pushed through these apps to continually improve the UTWS3.

Dual microphones for clearer calls

In addition to its capable audio performance, the UTWS3 also makes excellent calls. Both the left and right ear units have 2 built-in microphones. The primary microphone at the bottom of the unit picks up your voice, while the secondary microphone placed at a 90 ° angle from the primary picks up ambient noise that is filtered out by the Qualcomm CVC noise cancelling technology. Together these microphones give you crisp and clear calls.




The large touch button only requires a light 60g of force to activate, and has been designed to correctly reject unintended touches as well as eliminate any negative tactile feedback. Easily access the controls with just simple taps.

Simple ultra-

light touch controls

Independent amplifier architecture Easily drive multi-driver earphones

The UTWS3 sets itself apart from other wireless audio accessories with its emphasis on sound quality. Its high-performance headphone amplifier chip reduces distortion and greatly increases output power to better drive multi-driver headphones. It also has an analog volume adjustment system, for improved dynamic range and signal-to-noise ratio for even better audio performance. 


increase in transmission capacity


increase in range

The Bluetooth 5.0 Qualcomm QC3020 chip in the UTWS3 provides higher transmission speeds, as well as more stable signal connections and shielding against interference. This chip allows for high-resolution Bluetooth transmission that truly enables you to enjoy true wireless freedom without compromises no matter what you're doing.
