Unprecedented True Wireless Receiver with Independent DAC

The UTWSS is the first true wireless receiver utilizing an independent AK4332 DAC. Compared to the previous generation, the amplifier of the UTWS5 has a lower noise floor,high signal-to-noise ratio, and higher output power by 40%!

Reaching New Heights with Bluetooth Flagship Qualcomm OCC5141

One must continue to challenge one's self to continually set new bars of excellence. The Qualcomm QCC5141 in the UTWSS 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 apt Voice high-definition voice technology.

Third-Gen TWS Mode Lower Latency and More Reliability

Qualcomm's third-gen TWS Mirroring as utilized on the UTWSS 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 a 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 32k-tz 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.

High Marks for More Adjustable Levels

Compared to the previous generation, the UTWS now features 32 levels of volume adjustment instead of 26 levels to let you more precisely set how loud you want your audio.

Give Your Earphones Arriere Secure Home

The included charging care not only features a sturdy construction to petter protect your earphones, but also spor arge capacity to accommodate a greater varity of earphones attached to the UTWS5 ins it more convenient for charging, pan vitching, and other operations.

connect to Two Devices Simultaneously Via Bluetooth Switch to Either Device You Want

The UIWSs can be connected to two mobile phones at the same time. Just pause music on one of the mobile phones, and freely switch to the other one to listen to music or answer a call.

10 Band PEO Precise Tuning Born for Good Sound

The PEQ (Parametric Equalizer function was designed for the FW5, which supports 10-band self-defined tuning. On the FiiO Music App or the Fio Control App, users can self adjust the frequency, gain level. @ value, etc, achieving more accurate frequency response among every frequency range while ensuring high- fidelity sound quality. Also, it supports up to 192kHz/24bit under PEQ style.

Every Touch Carefully Designed Ultra-Sensitive, Large Buttons

The UTWS is not a case of form over function. The attractive large tactile button not only looks and feel better than ordinary buttons, but has also been engineered for improved responsiveness and reduce false touches. With simple taps, you can quickly access the controls you want.

Mach Own Invisible Raincoat TPX4 Water Resistance

With an IPX4 rating, no need to worry about the UTWS5 k3 being damaged by water or sweat as you go about your life, PA rated as defermined by passing rigorous testing in FiiO Labs.
