Astell&Kern AK UW100 MKII True Wireless Earbuds

Overview

AK UW100 MKII comes with a High Resolution 32-bit DAC, which is difficult to mount on a TWS, and a full range Balanced Armature driver that offers precision sound, delivering outstanding Hi-Fi sound even in a wireless setup. In addition, with best-in-class PNI (Passive Noise Isolation) and aptX™ Adaptive, along with the ergonomic design and latest high-resolution codecs, it offers the most advanced True Wireless Sound to date.

We were able to further enhance the AK UW100 MKII with a more advanced internal circuit design. The AK UW100 MKII reduces noise through digital circuit separation, and the newly designed circuit structure ensures a more stable connection to the host compared to its previous model, AK UW100. Additionally, the internal design was improved by adjusting the position of the BA driver and re-designing the acoustic chamber. With the optimization of electric currents, the earbuds can be played for up to 9.5 hours continuously, and offer 29 hours of maximum playback, so you can enjoy Hi-Fi sound anytime, anywhere.

Advances for more complete wireless sound

Astell&Kern’s long-standing, fundamental principle is the reproduction of sound as true to the original source as possible. The AK UW100 MKII, a true wireless earphone, based on our proprietary audio technology, provides uncompromising wireless Hi-Fi sound with no cables required.

A rarity for True Wireless Stereo (TWS*), the AK UW100 MKII has a separate embedded high-performance 32-bit DAC as well as a Balanced Armature driver for accurately reproducing sound, allowing the delivery of precise, high-quality audio with no loss of detail. aptX-Adaptive audio codec support for exceptional audio quality is the final flourish, ensuring the AK UW100 MKII is ready for wireless Hi-Fi sound.

Combining all these features with ergonomic design and best-in-class Passive Noise Isolation (PNI), the AK UW100 MKII takes your listening experience to a dimension where only you and the artist exist.

A New Design for Enhanced Perfection

Astell&Kern has further improved on the highly regarded TWS design of the AK UW100 to provide an even more perfect solution. AK UW100 MKII offers the ultimate Hi-Fi sound—the pinnacle of Astell&Kern’s technology and expertise.

The position of the BA driver has been moved towards the inside of the ear to better deliver the finer audio details more directly, and the acoustic chamber structure and mesh size have been re-designed multiple times in accordance with the new BA driver position to deliver the optimal sound output. The new design took numerous attempts to minimize sound diffusion to provide a more delicate and dynamic performance and a richer high-frequency expression.

AK UW100 MKII are a completely wireless earphones with unrivaled 32-bit DAC technology, and the AMP and circuit technology of Astell&Kern enables separation of the digital parts and analog circuits of the wireless earphone. This new design allows for further reduced noise than the previous model, offering clearer sounds with higher separation levels.
