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 UW100MKII 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.

Astell & Kern AK UW100MKII Main Features

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 UW100MKII offers the ultimate Hi-Fi sound-the pinnacle of Astell&Kern's technology and expertise.

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 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. comparable to that of ANC,

Notably, AK UW100MKII's noise cancelling capability 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.

Continue the Joy of Music

We completely redesigned the power system to increase the playback time significantly, which is one of the important performance factors in TWS, while not compromising on the most important sound quality. Through new internal design and current optimization, we were able to maintain the earbud size while dramatically reducing the cradle size and significantly increasing the playback time.

Now, you can enjoy the AK UW100MKII all day without worrying about recharging, with AK UW100MKII. Approximately 9.5hours of continuous playback, and up to 29 hours of total playback, never miss a beat with the AK UW100MKII.

Alongside the convenience of wireless charging, AK UW100MKII also supports fast charging, so you can charge for 10 minutes to play for an hour.

DESIGN

The AK UW100MKII is the first Hi-Fi TWS device based on Astell&Kern's proprietary sound technologies. As with in-ear monitors (IEMS), it delivers the richness of the original sound intact and free from distortion, Il through the freedom of wireless.

Just as Astell means "star" in Greek and Kern means "center" in German, so too Astell&Kern symbolizes the company's core identity of representing the center of music. This identity also shapes the design philosophy of the AK UW100MKII: the beauty of music is symbolized by a single star (Astell), embodying the twinkling and scattering of starlight.

The product design emphasizes the contrasting surfaces, allowing users to appreciate the shapes, colors, materials and finishes used in the earbuds and how they play with the light, and to picture in turn the stellar beauty and delicacy of the sound created by Astell&Kern as it is focused and diffused.

Designed to fit snugly in the ear, the earbuds' shape is transformed from a pentagon to a circle, just as the sound flowing through them transforms when it is gathered, refined and then reproduced with clarity.

The AK UW100MKII cradle design combines two pentagon-shaped ear buds, representing the continuity of light and shade, the identity of Astell&Kern. The existing AK UW100 cradle actively displayed the identity of AK. However, with the AK UW100MKII, the cradle keeps the essence of Astell&Kern design and enhances it further whilst increasing portability.

Great value for the price but be patient with connectivity

It may take a few tries to connect to your phone, especially if you have upgraded the OS or changed phones, but it gives an authentic audiophile experience. It's a significant upgrade from the glitchy first version.

Full range BA? Fantastic

The coherency and spatial information on these TWS are incredible. The EQ presets work brilliantly to help tailor the sound. They fit comfortably, even though they look like they shouldn’t. I absolutely love them.
