AK HB1 incorporates ESS’s ES9281AC PRO DAC for exceptional noise control and unparalleled ultra-high-quality Hi-Fi sound performance.
Adding to this, 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.
While maintaining a compact form factor of 33 x 68.4 x 16.5 mm, we used micro resistors and capacitor parts to achieve a small footprint without compromising performance. Carefully selected ultra-small tantalum capacitors, which are used in AK player products to create a stable system and audio performance by controlling the power fluctuations, are also included to create an optimal audio circuit design. In addition, the output and audio performance are enhanced with Astell&Kern's unique power management technology to minimize current consumption in respect of the connected device.
Dual Noise Shielded Cable
To ensure optimal usability across both Android and iOS devices without the need for additional adapters, AK HB1 features an interchangeable
cable that readily supports Type-C and Lightning connections.
The AK HB1 features a dual shielded cable to minimize noise and deliver a more vivid, original sound.
The copper core wire is coated with tin to prevent corrosion and strengthen tensile force for enhanced durability.
Additionally, the entire cable is wrapped in an aluminum film to block noise with an extra layer of shielding around the power cable to further minimize noise, the biggest issue in audio, then the tin-coated copper wire is woven to minimize noise interference to sound.
Finished with a fabric jacket on top of the TPE jacket, the cable features enhanced durability and usability with perfect aesthetic appeal.
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, AK HB1 seamlessly switches to Bluetooth mode, whenever a Bluetooth signal is received while using the USB DAC function.
High Compatibility and 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 your gaming device such as PlayStation and Switch, and enjoy low latency and enhanced sound for an immersive gaming experience.
Seamless Experience Extended to Cars with Car Mode
Activate AK HB1's dedicated Car Mode to enjoy high-quality DAC/AMP sound effortlessly while at the wheel. Simply connect 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.
LED Indicators for Real-time Status
Two LED lights positioned on the side of the AK HB1 give you an overview of the current device status such as the file type being played and battery information.
