Unprecedented Wireless Hi-Fi Quality: The 2nd Story

The AK UW100 realized A&K's philosophy of "delivering music authentic to the original sound," even in TWS earphones, and attracted much interest due to its unique design and best-in-class sound.

Based on that positive reception, A&K continued R&D to create a next-gen TWS, and as a result, is proud to present the AK UW100MKII, a new premium TWS that conveniently delivers the ultimate sound anywhere, at any time.

AK UW100MKII comes with a high-resolution 32-bit DAC (not easily mounted on a TWS) and a full range BA driver that offers precision sound, delivering outstanding Hi-Fi audio even in a wireless setup. In addition, it features best-in-class passive noise isolation, aptX™ Adaptive, ergonomic design, and latest high-resolution codecs, offering the most advanced TWS audio to date.

New Design for Enhanced Perfection

Astell&Kern improved on the highly regarded AK UW100 for a more perfect solution. The position of the BA driver has been moved toward the inside of the ear to better deliver audio details more directly, and the acoustic chamber structure and mesh size have been redesigned in accordance with the new BA position to deliver optimal sound output. This new design took numerous attempts to minimize sound diffusion to provide a more delicate and dynamic performance and richer high-frequency expression.

AK UW100MKII are completely wireless earphones with unrivaled 32-bit DAC technology. The AMP and circuit technology of A&K enables separation of digital parts and analog circuits of the earphone. This new design further reduces noise over the previous model, offering clearer sounds with higher separation.

Wow the sound on these buds are amazing!! Big sound stage, crystal clear, great instrument separation, truly a very pleasant and comfortable listening experience!!! But that is what they are ,if you are someone looking for just great sounding buds, I highly recommend!! If you are looking for ANC with bells and whistles and sound is not the lead priority then these are not for you. For me Great 5 stars!!!

Clear, detailed sound

The Mk2s are clearly an improvement over the first UW100s. Detailed, crisp sound! I also think the passive noise cancellation is very good, as active noise cancellation can muffle or distort details in some other wireless headphones ive owned.
