Astell&Kern, the worldwide leader in premium high-resolution audio equipment, introduces the AK UW100, its first truly wireless earbuds. These earbuds are built on Astell&Kern’s audio technology proficiency to produce a class-leading, fully wireless hi-fi-grade sound, staying true to the company’s concept of creating sound reproduction that is as near the original as possible.

A dedicated high-performance 32-bit DAC support for the latest high-quality wireless networking choices aptX Adaptive and Bluetooth 5.2, and ultra-detailed Knowles Balanced Armature drivers all contribute to the AK UW100’s exceptional sonic credentials.

The AK UW100 is designed for a cleaner, more accurate, and dynamic audio performance thanks to its separate and dedicated AK4332 32-bit high-performance DAC, which works in tandem with Astell&Kern’s unique AMP technology used in its award-winning DAPs.

The AK UW100 uses Knowles Balanced Armature drivers, which were chosen over more common dynamic drivers for their ultra-detailed performance, to produce distortion-free and realistic audio across all kinds of music.


The next-generation, high-quality aptX Adaptive codec is enabled to achieve the AK UW100’s superior wireless performance, expertly modifying the bite rate depending on the wireless medium it is operating in to decrease latency difficulties. 

It can support up to 24-bit audio at a bit rate of 420kps. When streaming from a compatible gadget such as an Astell&Kern portable digital audio player, cellphone, tablet, or laptop, support for Bluetooth 5.2 delivers increased range and a more robust wireless connection. 

Additionally, anyone with a smartphone operating Qualcomm True Wireless Stereo Plus will benefit from a more stable connection between both earphones and the compatible device, as well as seamless pairing and lower power consumption.


The AK UW100 offers excellent passive noise isolation (PNI) for a totally immersive environment when listening to music in noisy situations, thanks to the lightweight and ergonomic earbud implemented effectively through many simulations. 

PNI effectively reduces undesirable ambient sounds in the mid and high range, unlike conventional Active Noise Cancellation, which focuses on filtering out low-frequency noise. A single press of the left earbud activates the ambient mode, which allows the user to move between the four ambient levels via the earbud’s touch controls or from the app effortlessly.

Touch controls, ambient levels, and different EQ settings may all be customized via a unique iOS and Android app.

Users may listen to music all day thanks to the earbuds’ six-hour battery life and an additional 18 hours via the case (for a total of 24 hours). The AK UW100 charging case not only supports wireless charging but also supports quick charging, with only a 10-minute charge offering an hour of playing.

To deliver crystal-clear audio call quality, a dual mic setup combines a Voice Communication Package (VCP) from vocal application expert Alango. These wireless earbuds successfully suppress noise in a range of settings and environments, constantly ensuring call stability, thanks to innovative Acoustic Echo-Canceller and Noise-Suppressor technology.
