At its core is the powerful Qualcomm QCC5181 quad-core chip with two integrated Kalimba DSPs. Thanks to Snapdragon Sound support, it ensures particularly detailed and lossless audio playback. The Air Link transmits music in Hi-Res quality with up to 96 kHz at 24-bit using modern codecs such as LDAC, aptX Lossless, and aptX Adaptive.

Operation is conveniently done via a multifunction button or alternatively through an app and web interface. Through this, connections can be managed, firmware updated, and Bluetooth codecs switched. A separate USB-C port allows for simultaneous charging and music playback, making the Air Link particularly practical for everyday use. The integrated RGB LED displays the active codec and connection status at a glance, color-coded and intuitively. Weighing only five grams, with a robust, oxidation-resistant housing and a minimalist design, the FiiO Air Link combines cutting-edge technology with maximum user comfort. Its simple plug-and-play usage allows nearly any device to be enhanced with high-quality Bluetooth functionality.
