Hi-Fi design
The compact housing of the ear hooks contains a fully independent HiFi DAC/AMP system. High-definition signals are processed by the Bluetooth chip QCC5181 and passed digitally to the AK4333 DAC for precision decoding and amplification. The result is a true high-resolution HiFi experience, but delivered with wireless convenience.
Dual DACs
Utilizing a dual DAC design, each channel is equipped with a dedicated 32-bit AK4333 DAC. Engineered for high performance and efficiency, these chips feature built-in amplification and AKM's signature VELVET SOUND technology. Optimized for TWS, they deliver a breathtakingly rich and detailed audio experience.
Built-in amplifier
Designed to work with most IEMs, the Link TWS (UTWS17) has improved output power and lower distortion compared to the previous UTWS5 model.
Audio architecture
Powered by a quad-core architecture and dual 240MHz Qualcomm Kalimba audio DSPs, the UTWS17 delivers ample computing power. It effortlessly handles complex decoding and multitasking for bit-perfect lossless audio. Its Bluetooth design also supports Snapdragon Sound technology* for an immersive, high-definition wireless audio experience. *Snapdragon Sound™ requires a compatible device that also supports the technology.
Better Bluetooth
LINK TWS supports various Bluetooth codecs including aptX Lossless, LDAC, LHDC V5 (192kHz/24bit)*, and aptX Adaptive (96kHz/ 24bit). With wireless bit rates of up to 1.2Mbps, you can experience true CD-quality lossless audio with compatible devices. Every nuance is restored with such clarity that you'll feel like you're standing right in the middle of the live performance.
Lower latency
Activate aptX Adaptive and enter game mode with a single tap, slashing latency to as low as 74.6 ms. Experience perfect sync between your actions and the audio. Pinpoint enemies by sound and strike with precision when every millisecond counts.
Make calls
Featuring 32kHz aptX Voice ultra-wideband audio, each ear hook utilizes a dual-mic array and an upgraded CVC algorithm to enhance call clarity. This system filters ambient noise and captures your voice, ensuring the person on the other end hears you more clearly and naturally than the previous generation.

Interchangeable ear hooks
LINK TWS (UTWS17) comes standard with swappable MMCX and 0.78mm 2-pin connector adapters. This versatile design allows one pair of ear hooks to support both connector types, eliminating the need to buy separate versions for different earphones. *MMCX design is not compatible with Sennheiser. The 2-pin connector is non-recessed, so it is not compatible with some Moondrop, Campfire, Plunge, and others.
From the choice of exterior materials to the internal design, every detail has been meticulously optimized for a better fit and sound. Weighing only 8g, each ear hook features an ergonomic design coated in a skin-friendly, food-grade nano-finish. Internally, audio signals are carried by silver-plated monocrystalline copper wiring. This superior conductivity lays the foundation for high-quality sound.
Simple controls
With just a tap of a single button on each ear hook, seamlessly manage playback, volume, and previous/next track. Intuitive control is always right at your fingertips.
Charging case
The new spacious charging case offers enhanced protection and accommodates a wider variety of earphone shell sizes and ear hooks. The case now features an OLED dot-matrix display that provides real-time status updates, allowing you to easily monitor pairing status and battery levels for a hassle-free experience.
Similar products use charging contacts internally within their cases, which can experience problems like oxidation and dirt buildup over time. The contactless wireless charging design eliminates these issues, significantly boosting long-term durability. The UTWS17 also enables intelligent features including automatic power-off when placed in the case, automatic power-on when removed, and charging stop when fully charged. Enjoy up to 7 hours on a single charge of the ear hooks, and 20 hours total battery life with the charging case. *Due to energy loss during wireless charging, the ear hooks may feel slightly warm to the touch after charging. This is normal behavior and does not affect safety. Please note, the charging case must be charged via wired USB-C and does not support Qi wireless charging; it is only the internal case-to-earhook connection that is wireless.
Resilient against sweat and splashes, the UTWS17 is ready for daily life. Enjoy your music with total confidence across different environments.
FiiO Control app
Use the FiiO Control app to easily configure various settings, including equalizer, multipoint connection, channel balance, as well as toggling between HiFi and Game modes.
