Experience the Freedom of Music


The AK HB1 Bluetooth and USB Type-C DAC/Amp is a lightweight, portable device with a powerful built-in amplifier and a premium microphone that lets you effortlessly experience high quality audio wirelessly and through USB Type-C and Lightning connections.


Supreme connection with Hi-Fi sound

AK HB1 goes beyond simple Bluetooth playback, delivering outstanding, full high-resolution sound via USB DAC connection to PCs, smartphones, tablets, and more. Supporting Native DSD256 and 32 bit/384 kHz playback, AK HB1 ensures compatibility with a diverse range of high-quality audio sources, providing Astell&Kern's signature premium sound quality. Additionally, equipped with a renderer function that supports MQA 8X, AK HB1 enables MQA playback without the need for external DACs or playback devices.

Extensive Codec Support

The AK HB1 accommodates an extensive selection of codecs to deliver smooth playback of high-resolution audio through its compatibility LDAC and aptX HD codec as well as the more common AAC and SBC for PC and smartphones. AK HB1 is also equipped with Qualcomm’s CSR8675 Bluetooth for a consistently strong and stable connection.

Exclusive AMP Circuitry

AK HB1 introduces an exclusive AMP circuitry that supersedes the standard built-in DAC AMP. Its AMP enables a commanding 4 Vrms output (in Balanced connection) and dual connectivity options — 3.5 mm unbalanced and 4.4 mm balanced, catering to a wide range of IEMs and headphones.

Simultaneous Support for UAC 1.0 & 2.0 for Gaming

While modern smartphones, tablets, and PCs support UAC 2.0 connections, many gaming devices still exclusively support UAC 1.0 connections. To cater to both scenarios, AK HB1 ensures compatibility by supporting both UAC 2.0 and UAC 1.0 connections for cross-platform quality sound experiences. Connect AK HB1 to gaming devices such as PlayStation and Nintendo Switch, and enjoy low latency and enhanced sound for an immersive gaming experience.

Crystal-Clear Voice

The AK HB1 is built with a high-quality microphone to ensure crystal-clear voice quality and stability. Ideal for taking calls when working, gaming, or travelling, the Bluetooth DAC/Amp is equipped with Clear Voice Capture technology to suppress ambient noise while delivering clear vocals to the recipient.
