Astell&Kern HC2 Portable DAC and Headphone Amp - Open Box
Description
The Astell and Kern HC2 is a compact USB DAC designed for listeners who want real high resolution sound from their phone, tablet, or computer. Modern devices keep removing headphone jacks and often rely on weak internal audio, which makes it harder to enjoy wired earphones at their full potential. The HC2 solves this with dual Cirrus Logic CS43198 DACs, a balanced 4.4 mm output, and clean power management drawn from Astell and Kern's portable players. It delivers powerful output, low noise, and accurate detail for any wired earphones or headphones that need a proper source.
Key Features
- Dual Cirrus Logic CS43198 DAC chips with native DSD256 and 32 bit 384 kHz PCM support
- 4.4 mm balanced output with up to 4 Vrms for better separation and lower noise
- Rear output design that reduces noise found in typical USB dongles
- Dual shielded cable to protect the audio signal from interference
- Compact aluminum housing with refined build quality
- Plug and play support for Android, iOS, Windows, and macOS
- Optional Astell and Kern companion app on Android for volume control and device settings
- Roon Tested for reliable integration
Use Case
The HC2 is ideal for listeners who want a step up in audio quality from any mobile device or laptop. The balanced 4.4 mm output works well with sensitive IEMs and medium impedance headphones. It is suited for streaming, portable high resolution listening, and improving clarity on the go without the size of a full portable player.

FAQ
Does the HC2 work with iPhones
Yes. The included USB C to Lightning adapter allows direct connection to modern iPhones.
Can I use the HC2 with high impedance headphones
The balanced 4.4 mm output provides up to 4 Vrms which is enough for many portable headphones. For very high impedance models a larger amplifier may still offer better control.
Is the HC2 compatible with all Android phones
Most modern Android devices work without additional software. Some phones may require the Astell and Kern app for volume adjustment.
Can the HC2 be used with an Astell and Kern DAP
No. The HC2 cannot be used as an external DAC for Astell and Kern players due to fixed maximum output volume.
