True lossless Hi-Fi Bluetooth earhook design

Wired sound quality, wireless freedom

Gives headphones with interchangeable cables the wings of wireless Hi-Fi.

Combines FiiO’s long-standing TWS Bluetooth amplifier technology and brings the sound quality of wireless Bluetooth up to the level of wired headphones.

In addition, innovative designs such as wireless charging via the ear hooks and interchangeable adapters offer you a truly unrestricted, lossless Bluetooth listening experience.

Wireless Charging System for the Ear Hooks

Contactless, sweat-resistant

The ear hooks feature a contactless charging system that completely eliminates the issues of oxidation and contamination associated with traditional charging contacts, significantly extending their lifespan. Additionally, smart features such as powering off when placed in the charging case, powering on when removed, and automatically stopping the charging process when fully charged are implemented.

Miniature decoder and headphone amplifier, complete Hi-Fi architecture

A complete Hi-Fi decoding and amplification system is housed within the compact ear hook casing

The high-resolution Bluetooth audio signal is processed by the QCC5181 and forwarded as a digital signal to the AK4333 for decoding and amplification, allowing you to enjoy high-resolution Hi-Fi sound quality even with the Bluetooth earhook headset.

Flagship Bluetooth chip QCC5181, a benchmark for performance

The quad-core processor architecture with two integrated 240 MHz Qualcomm Kalimba audio DSPs provides ample computing power for audio processing. It effortlessly handles complex audio decoding and multitasking, ensuring smooth playback and lossless audio. At the same time, it supports Snapdragon Sound technology*, which delivers an immersive, high-resolution wireless audio experience.

*Snapdragon Sound technology must be paired with devices that also support this technology.

High-resolution Bluetooth encoding for all formats, lossless transmission in CD quality

Supports Bluetooth formats such as aptX Lossless, LDAC, LHDC V5 (192 kHz/24-bit), and aptX Adaptive (96 kHz/24-bit), with a wireless lossless transmission rate of up to 1.2 Mbps. This delivers true lossless, CD-quality sound, reproduces rich audio details, and puts you right in the middle of the action.

aptX Adaptive with low latency

Gaming mode – secure the victory

Enable aptX Adaptive encoding and switch to gaming mode with a single click – with a latency of just 74.6 ms.

Sound effects and combo actions are reproduced seamlessly, allowing you to pinpoint your opponent’s position based on sounds and attack with precision—victory is decided in a fraction of a second.

aptX Voice 32 kHz wideband voice transmission

Two microphones + CVC noise cancellation for uninterrupted communication

Supports aptX Voice at 32 kHz for crystal-clear voice transmission. Combined with two microphones on the ear hook and an improved CVC noise-cancellation algorithm, ambient noise is effectively filtered out and voices are captured with precision. Even in noisy environments, the person you’re talking to will hear you loud and clear.

Two AK4333

Dual DAC bridge, double the performance

The dual-DAC design features an AK4333 DAC with 32-bit processing capability for each channel. It is characterized by high performance and low power consumption, features an integrated headphone amplifier function, and is complemented by VELVET SOUND technology—specifically developed for TWS—to deliver an outstanding audio experience.

A safer “home” for your earbuds

New display, instant status overview

The spacious charging case offers your earbuds safer protection and is designed to accommodate earbuds of various sizes* as well as the ear hooks simultaneously. The charging case also features an OLED dot-matrix display that shows real-time information about the earbuds’ status, giving you a quick overview of earbud pairing, battery level, and other details for an even more worry-free experience.

* The dimensions listed above apply to the FH19 earbuds. Since the interior of the LINK TWS has an irregular shape, the dimensions are only a guideline; the actual fit during use is ultimately what matters.

B Battery life of the earbuds per charge: approx. 7 hoursB

Total battery life (earbuds + charging case): approx. 20 hours

One pair of ear hooks, compatible with two connector types: MMCX and 0.78 mm two-pin

The package includes adapters for MMCX and 0.78 mm two-pin connectors. Thanks to the practical interchangeable design, one pair of ear hooks is suitable for both connectors, so you don’t need to buy additional versions due to different connectors.

Details inside and out – all for comfort and sound quality

From the materials to the construction, every detail has been carefully designed for comfort and high sound quality

Lightweight comfort: Each ear hook weighs only approx. 8 g. Thanks to the combination of the ear tip and ear hook, as well as a skin-friendly, food-grade nano-coating, it sits securely and comfortably without easily falling out during exercise.

High-fidelity transmission: The audio signal is transmitted via a silver-coated single-crystal copper wire, which is characterized by excellent conductivity and resolution—laying the foundation for great sound right at the source.

Super-light, large-surface buttons – user-friendly and always within reach

Responds instantly to a light touch and allows you to control pause/play, volume, and track selection with just a single press. User-friendly touch controls – everything at your fingertips.

· Pause – press twice briefly

· Resume playback – press once briefly in pause mode

· Volume control – press briefly on the left ear (+) / press briefly on the right ear (-)
