Astell&Kern Introduces The AK UW100MKII - A High-Resolution True Wireless Earbud
Knowles Balanced Armature Drivers For Super Detailed & Accurate Sound
The Astell&Kern AK UW100MKII features a Knowles balanced armature driver to provide high-quality audio with precise details. The extraordinary driver has been moved towards the inside of the ear with a redesigned acoustic chamber and mesh size to audio with perfect accuracy. This design minimises sound diffusion and delivers more refined vocal clarity and crisp treble with excellent dynamic response.
Gesture Control
Astell&Kern AK UW100MKII features a gesture control on both the earbuds to access with many features.
Meticulous Design
Astell&Kern AK UW100MKII is meticulously designed with contrasting surfaces of shapes, colours and high-quality materials for impeccable aesthetics.
Charging Case
Astell&Kern AK UW100MKII equips a Type-C port to charge the case and the earbuds for an extended listening journey.
With one balanced armature, the UW100MKII is able to deliver a great sound, with more details and transparency than most true wireless earbuds are capable of.
The UW100MKII have a feature common in true wireless earbuds: automatic wearer detection, so they can pause music when you remove them and resume it when you put the buds back in your ear.
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.
