Product Details

↓ Details provided by FiiO

From Audio46: The 2-pin connector is FLAT. Please check if your IEM is flat or recessed before purchasing. For example, MoonDrop IEMs have a recessed 2-pin, meaning the connection will be loose and potentially unreliable. (Earphones is not included)

FiiO UTWS5 DAC Chipset

Reaching new heights with Bluetooth Flagship Qualcomm QCC5141

One must continue to challenge one's self to continually set new bars of excellence. The Qualcomm QCC5141 in the UTWS5 brings two major upgrades compared to the previous generation QCC3020. Not only does the QCC5141 bring a significant leap in decoding high-resolution music, it also brings a significant improvement to calls with support for aptX Voice high-definition voice technology.

Third-gen TWS mode Lower latency and more reliability

Qualcomm's third-gen TWS Mirroring as utilized on the UTWS5 effectively reduces latency and instability for a better experience. Unlike TWS+, TWS Mirroring allows for seamless switching between being connected to the main and secondary ear units. This allows for greater compatibility with various Bluetooth devices, all with lower latency and more reliable connections.

Bluetooth 5.2 96kHz/24bit Hi-Res audio support

Thanks to the Snapdragon sound suite of technologies, you can truly experience wireless high-resolution sound no matter what you are doing. Support for aptX adaptive allows you to listen to 96kHz/24-bit high-resolution audio all with lower latency. And aptX voice enables 32kHz super wideband voice calls for true high-definition calls over Bluetooth.

Truly unshackled Wireless charging

The charging case not only has an enormous 800mAh battery that can provide up to 30 hours of battery life, but is also capable of wireless charging - for the ultimate convenience of true freedom from cables.
