I think that Astell & Kern did a fantastic job with the UW100MKII: they sound great and offer the right amount of functionality, prioritising sound quality over gimmicky features.
The default EQ mode was our go-to for most genres, preserving high-frequency clarity while maintaining enough low-end oomph.
The detail and ultimate fidelity of the playback is one of the best I’ve ever heard from a True Wireless earphone. The resolving power of the design really lets the listener peer into the music.
The transition from the upper midrange into the treble is rather seamless with very good clarity and detail. Percussion has excellent snap.

Astell&Kern UW100MKII TWS earbuds

It is a decent, value for money product TWS earbuds. The sound quality is amazing and can match with pricey earbuds. The tonal quality is clean and the soundstage is wide.

Amazing Earbuds but App Issue

The earbuds sound is great. Better than Realme buds Air Pro 5 which is already quite good. I tried all kinds of music and it was able to do well in most music. Treble and bass are well balanced while the mids are a bit muffled
For the android app issue (those on latest android), people can download APKPure app and then download AK Control version 1.1.009 and able to use the app. (Please download APK from trusted apps/sites)
Great product, app issue - Hence 3 out of 5

AK again shows its passion for music and maintains their typical music alone policy.

Design: I own many Astell&Kern products and exquisite, exclusive, and elegant design is something which they on all their products including the UW100MKII. From the cradle to the earbuds and to the eartips, everything screams quality. It has good build quality too.
Comfort: I was initially skeptical about this particular area due to the typical sharp cuts and unique design of the earbuds but was satisfied once I had found the right eartip size.
Sound: The lows are well textured, the mids are organic and the highs are quite well extended for a TWS. The soundstaging and imaging are two standout qualities of these earbuds.
Conclusion: I was very satisfied with almost everything except for the touch interface that is neither tactile nor responsive, in fact if truth be told it is quite erratic. Nevertheless, these are some of the teething troubles that could be ironed out in the future through firmware upgrades. All in all I bought it for the sound quality and once the music starts to play, everything else becomes ephemeral.

Hi there! Thank you for taking the time to share your experience with the Astell&Kern - AK UW100MKII. We are glad to hear that you are satisfied with the design, build quality, and sound of the product. Happy listening!
