FiiO Link TWS UTWS17 True Wireless Bluetooth Ear Hook Adapter

Turn compatible detachable-cable in-ear monitors into a high-performance true wireless system with the FiiO Link TWS UTWS17. Designed for IEMs using MMCX or 0.78 mm 2-pin connections, the UTWS17 combines Bluetooth 6.0 connectivity, independent AKM DAC/amplifier circuitry for each ear, advanced Bluetooth codecs, and extensive sound customization through the FiiO Control app.

Powered by the Qualcomm QCC5181 Bluetooth platform, the Link TWS supports SBC, AAC, aptX, aptX Adaptive, aptX Lossless, and LDAC for broad compatibility with smartphones, tablets, computers, digital audio players, and other Bluetooth audio sources.

Independent AKM DAC & Amplification

Each ear hook features its own AKM AK4333 DAC with integrated Class AB amplification. This independent left/right architecture is designed specifically for driving in-ear monitors while maintaining detail, channel separation, and low-noise performance.

The FiiO Control app also provides access to selectable AKM digital filters, including Fast Linear, Slow Linear, Fast Minimum Phase, and Slow Minimum Phase settings.

Bluetooth 6.0 with High-Resolution Codecs

The Qualcomm QCC5181 platform provides Bluetooth 6.0 wireless connectivity and supports a wide range of audio codecs. LDAC supports transmission rates up to 990 kbps, while aptX Adaptive and aptX Lossless provide additional high-quality wireless options with compatible source devices.

• LDAC up to 990 kbps

MMCX & 0.78 mm 2-Pin IEM Compatibility

The Link TWS uses interchangeable connection modules rather than limiting the adapter to a single IEM connector. Both MMCX and 0.78 mm 2-pin modules are included, allowing the system to work with a wide range of detachable-cable earphones and in-ear monitors.

The connector modules can be exchanged without tools, making it easy to move the Link TWS between compatible IEMs.

10-Band Parametric EQ

The FiiO Control app provides a 10-band parametric equalizer for detailed sound adjustment. Three user slots, presets, and advanced controls allow frequency and filter parameters to be customized. EQ profiles are stored directly on the Link TWS, so configured settings remain active when switching to another compatible Bluetooth source.

Multipoint & Low-Latency Game Mode

Multipoint connectivity allows the Link TWS to maintain connections with two Bluetooth devices simultaneously. A dedicated game mode reduces latency for applications where synchronization between sound and video is important.

Transparency Mode

Built-in microphones provide a transparency mode that passes surrounding sounds through to the connected earphones. Transparency intensity can be adjusted from 0 to 16 through the FiiO Control app, allowing the amount of surrounding sound to be tailored to the listening environment.

Charging Case with Display

The included carrying and charging case features an integrated display for convenient status information. Pressing the case button displays Bluetooth connection status along with the battery levels of the case and individual ear hooks. Opening the case initiates pairing, with automatic reconnection available after initial setup.
