AK HC3 adopts dual ES9219MQ, the SABRE HiFi® DACs from ESS that is highly regarded by audio fans for its ability to playback Hi-Fi sounds such as MQA in ultra-high quality, excellent noise control, and low power consumption. In addition, it supports Native DSD256 and 32 bit/384 kHz, supporting any high-resolution sound to realize Astell&Kern’s unique sound experiences.
AK HC3 has been improved to be compatible with any 3- or 4-pole 3.5-mm plug earphones and headsets, as well as in-line controller and microphone features of 4-pole earphones and headsets. With AK HC3, you can enjoy a greater range of entertainment experiences with your mobile device. The direct USB connection provides lower latency compared to other wireless solutions, enabling a sound performance that’s perfect for gaming. The voice chat features enhance your gaming experiences, so you can play with others, and the microphone input makes it even more useful for professional web conferencing. Plus, the rich sound capability adds to the utility of AK HC3 by making your video experiences more realistic and immersive.
AK HC3 incorporates 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 AK 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.
The AK HC3 features a dual shielded cable to minimize noise and deliver more vivid, original sound. The copper core wire is coated with tin to prevent corrosion and strengthen tensile force for enhanced durability. In addition, the entire cable is wrapped in an aluminum film to block noise, the biggest issue in audio, then the tin-coated copper wire is woven to minimize noise interference to sound.
