Astell&Kern HB1 Bluetooth DAC & Amplifier

Easy and Convenient USB Plug & Play
AK HB1 simplifies the transition between Bluetooth and USB cable connections by supporting USB Plug & Play functionality. Connect AK HB1 to your PC or smart device using a USB cable to enjoy high-resolution sound while simultaneously controlling various settings and features through the app on your Bluetooth-connected smartphone. With BT Priority Mode enabled, the AK HB1 seamlessly switches to Bluetooth mode, whenever a Bluetooth signal is received while using the USB DAC function.

UAC 1.0 & 2.0 Support for Gaming
While modern smartphones, tablets, and PCs support UAC 2.0 connections, many gaming devices still exclusively support UAC 1.0 connections. The AK HB1 ensures compatibility by supporting both UAC 2.0 and UAC 1.0 connections for cross-platform quality sound experiences.

Now you can connect the AK HB1 to your gaming device such as PlayStation® 5 or Nintendo Switch™ to enjoy low latency and enhanced audiophile-quality sound for an immersive gaming experience.

Activate AK HB1's dedicated Car Mode to enjoy the same high-quality, audiophile DAC/AMP sound in your car. Simply connect the AK HB1 to your vehicle's AUX port, and its power automatically turns on/off based on your vehicle's ignition, allowing you to enjoy audio from paired devices.

Crystal-Clear Voice Calls with built-in mics
AK HB1 ensures crystal-clear voice quality and stability thanks to Knowles's high-quality MEMS microphone technology and Qualcomm's cVc Generation 8.0 call solution with Clear Voice Capture technology, which suppresses ambient noise while delivering clear vocals to the recipient. The AK HB1 also incorporates a 4-pole in-line MIC, enabling voice calls via wired earphones. With the AK HB1, you can experience enhanced call quality alongside AK HB1's exceptional Hi-Fi sound.

Smart Charging System
Astell&Kern’s AK HB1 automatically recognizes what type of device is connected via a USB cable and streamlining the charging process without requiring additional setting adjustments. Charging mode can also be turned on/off to allow simultaneous playback and device charging, preventing battery depletion during playback.
