The Astell&Kern AK UW100MKII are audiophile-grade True Wireless Earphones, globally released in September 2023. They stand out with a dedicated AKM AK4332ECB 32-bit DAC and a single Knowles Balanced Armature driver per earbud, prioritizing uncompromised sound fidelity over active noise cancellation.

Equipped with Bluetooth 5.2 and aptX™ Adaptive codec, the UW100MKII ensures high-resolution wireless audio. Its ergonomic design provides best-in-class Passive Noise Isolation (PNI). With Qualcomm cVc 8.0 technology and dual microphones, call clarity is excellent. Boasting up to 9.5 hours of earbud playback (29 hours total with case), fast and wireless charging, IPX4 water resistance, multi-point connectivity, and a customizable AK Control app, the 7g earbuds deliver premium sound and features in a distinctive, portable form factor.

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 UW100MKII, 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 UW100MKII 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 UW100MKII is ready for wireless Hi-Fi sound.

Combining all these features with ergonomic design and best-in-class Passive Noise Isolation (PNI),
the AK UW100MKII takes your listening experience to a dimension where only you and the artist exist.

Astell&Kern has further improved on the highly regarded TWS design of the AK UW100 to provide an even more perfect solution. AK UW100MKII 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 UW100MKII 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.

The Best Choice for Pure Sound– Enhanced musical immersion
AK UW100, the previous model, is equipped with highest-level PNI (Passive Noise Isolation),
and has been recognized as a true Hi-Fi TWS that fundamentally eliminates noise that may be caused by ANC and sound distortions, together with its outstanding noise-canceling performance.
The AK UW100MKII allows users to enjoy complete musical immersion with its excellent sound technology and highest-level PNI technology.

ANC is not essential to achieve both reduced ambient noise and increased musical focus. When combined with the thoroughly tried-and-tested ergonomic design of the AK UW100MKII, PNI is sufficient to reduce noise physically.

Unlike generic ANC, which concentrates on cancelling low-frequency noise,
PNI can efficiently cancel unwanted ambient noise in the mid and high ranges, as well as higher-pitched sounds.
Notably, AK UW100MKII’s noise cancelling capability is comparable to that of ANC, even for low frequencies. Another significant feature is that sound quality is retained, since noise is attenuated by the structure of the earbuds rather than by software.

Developed with the help of countless simulations, the AK UW100MKII's best-in-class PNI capability allows you to escape annoying ambient noise and to immerse yourself in an experience where only you and the artist exist.

If you wish to hear ambient sounds, just tap the left earbud once to activate ambient mode. You can switch between the four ambient modes by tapping or using the app.
