Dedicated DAC

With its separate and dedicated AK4332, 32-bit high-performance DAC (Digital-to-Analogue Converter), working in tandem with Astell&Kern’s proprietary AMP technology employed in its award-winning DAPs (Digital Audio Players), the AK UW100MKII is geared for a clearer, more accurate and dynamic audio performance.

Latest wireless technology

To realise the AK UW100MKIIs leading wireless performance, the next gen, high-quality aptX™ Adaptive codec is supported, expertly adjusting the bite rate according to the wireless environment it is operating to reduce latency issues (it supports up to 24-bit audio at a bit rate of 420kps).

Best in-class passive noise isolation

With an ergonomic and lightweight earbud design developed through countless simulations, the AK UW100 offers best-in-class passive noise isolation (PNI) to enable a truly immersive experience when listening to music in clamorous environments.
