Tiny body, huge reserves

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.

**Ear unit battery life for single use is about 5.5 hours, TWS+ mode about 7 hours, ear units can be charged 4-5 times with fully charged charging case

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.

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.

  • EQ adjustment
  • Channel balance
  • English/Chinese voice prompts
  • OTA upgrades (Android only)

Simple ultralight touch controls

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.

Close and comfortable fit

The improved metal memory ear hooks are comfortable, yet stay securely in your ear. This makes them perfect for any long music sessions, such as during exercise.

Monocrystalline silver-plated copper audio goodness
To catch more details in a flash

High-purity monocrystalline silver-plated copper material was carefully chosen for the inner audio wires of the UTWS3, for its fidelity and ability to resolve details, being noticeably better to acquire pure and high-fidelity music.

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.

Greatly improved performance

The Bluetooth 5.0 Qualcomm QC3020 chip in the UTWS3 provides higher transmission speeds, as well as more stable Greatly improved performance 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. Qualcomm TWS+ dual transmission Dual direct connections lower latency Note: TWS+ requires your smartphone's support. Some phones are unsupported or may have compatibility issues. 800% increase in transmission capacity 400% increase in range 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.

Convenience with OK sound

These were excellent and comfortable on the go. They don't sound as good as for example as my mojo but it does trick when you want something light and convenient.
