Astell & Kern AK300

The Astell&Kern is the ultimate portable high-fidelity audio system capable of playing Mastering Quality Sound (MQS) from music mastering studios. MQS refers to all of the high resolution digital music recording studio formats up to 24-bit/ 44 – 192kHz. MQS delivers vast amounts of better music experience because MQS delivers 6.5 times of the detailed information in the same track.

While succeeding the state-of-the-art DAC and scalability as applied to the AK380 and AK320, the latest model has improved accessibility by being priced at a reasonable level.

  • AK4490's Single DAC-DAC
  • DSD-to-PCM Playback
  • Parametric EQ with 20bands 0.01dB
  • 200 Femto Second VCXO Reference Clock
  • Exceptional Expandability
  • DLNA-based AK Connect App
  • Metal Touch Sensor Home Button


Astell & Kern AK T8IE MKII

The AK T8iE MkII succeeds and improves on the AK T8iE, the world’s first Tesla in-ear headphone, collaboratively developed by Astell&Kern and beyerdynamic. The new flagship model promises truly outstanding sound and exceptional build quality.

The AK T8iE MkII has high-grade silver-plated fiber cables with coaxial construction, an upgrade from copper cables. It also introduces a new voice-coil, drawing on all of the audio excellence beyerdynamic has pioneered since 1924. Despite its small size, the AK T8iE MkII allows users to experience an extremely wide frequency range, with crisp bass, well-balanced mids and crystal-clear highs.
Like its predecessor, the AK T8iE MkII, is hand-made by highly skilled engineers in Germany. Combining Astell&Kern's philosophy of "providing the original sound" with the expertise of beyerdynamic, the AK T8iE MkII sets a new benchmark.

  • New, improved voice-coil
  • High-grade transparent silver-plated cables
  • High precision gold-plated MMCX connectors
  • Great flexibility
