Astell&Kern AK HC3 DAC

The incredible Astell&Kern AK HC3 DAC is the perfect bolt on audio accessory for your smartphone. Ideal for both iOS and Android devices.

Connected to be Hi-Fi 

High-resolution sound on streaming services allows you to fully appreciate the rich tones and emotional nuance of your music.

However, as headphone ports disappear on smartphones, it makes it increasingly difficult to use wired earphones that deliver high quality sound, and people experience the limitations of wireless transmission and slow response speeds. Music lovers who wish to enjoy true high-quality Hi-Fi sound rather than what is currently being delivered by smartphone wireless standards and computers’ built-in sound cards are becoming deeply concerned.

Key features

• ES9219MQ Dual DAC from ESS for true Hi-Fi quality
• Proprietary app for android devices for detailed volume control
• Mic input enables more entertainment and voice features for gaming and conferencing
• Compatible with iOS devices
• Dual shielded cable and full metal housing design for long lasting use

The Choice for Hi-Fi Sound – Ultra High-Resolution Sound From Dual DACs

The Astell&Kern HC3 USB-C Dual DAC Cable features two ESS ES9219MQ DACs that graces only a select few products with ESS DACs proven and celebrated by music lovers.

The HC3 provides Native DSD256 and 32-bit/384kHz support that enables it to play back high-quality sound files so you can enjoy the luxury and premium sound quality of Astell&Kern.

Unique, noise-free design

Unlike most DAC products, the AK HC3 incorporates a rear output design to minimise noise as much as possible. By processing the digital signal after it has travelled through the dual noise shielded cable, the resulting sound is far superior and virtually noise free.

The Result of AK’s Ultra-Fine Audio Design Technology

With its compact size and uncompromising performance, the HC3 makes it easy to enjoy real Hi-Fi sound anytime, anywhere.

Astell&Kern is adored by countless music lovers thanks to our dedication and meticulous delivery of the original sound with our signature DAPs, or portable high resolution audio players.

We included the Astell&Kern technology and know-how that has been accumulated from our DAPs over the years in this small device, measuring just 14x53mm.

We used micro resistors and capacitor parts to achieve the small dimensions without compromising performance. Tailored 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 the optimal audio circuit.

In addition, the output and audio performance are enhanced with Astell&Kern’s unique technology while minimizing current consumption in consideration of the connected device. This enables you to enjoy the original sound without any distortion even when using high-impedance headphones or sensitive earphones.

Easy and Convenient – Plug & Play

Connect directly to a Windows PC, Mac, smartphone or tablet with a USB-C port that supports plug & play, without needing a separate conversion adapter, and enjoy high-quality sound.

The HC3 utilizes power from the connected playback device so it does not need to be charged or be connected to a separate external sound card, AMP or DAC. Just connect HC2 to experience high-fidelity sound from a computer or mobile device.

The Astell & Kern AK HC3 is also compatible with iOS devices using the included USB-C to Lightning adapter.

*TRS and TRRS 4.4mm earphones and headphones can all be used, but note that the in-line controller and microphone features of TRRS earphones and headphones are not supported.

Noise-Free Rear Output Structure

HC3 has a rear audio output design to minimize noise. Most USB DAC products have the DAC positioned in the USB terminal that is connected directly to the device to process and output audio.

However, with the HC3, digital signals from the device go through the dual shielded cable to the audio circuit before being converted to an analog signal by the DAC. By processing the digital signal after, the result is superior, noise-free sound compared to other USB DAC products.

Volume Control Through a Dedicated Android APP

As is common with USB DACs, compatibility issues can arise such as different connected devices being set automatically to maximum volume output or playback at too low volume.

To resolve such issues and offer more greater control over volume and function of the HC2, we have developed a companion app for Android OS devices.
