Reviews-base

"Astell & Kern’s first true wireless buds are a compelling pair, putting in an astute, clear and natural audio performance. Their passive noise isolation blocks out sounds impressively to keep the outside world from invading your music playlist, and the Ambient mode brings clarity and awareness for those who want to be engaged with the world around them."
Trusted Reviews, Recommended Award

"The UW100 sound simply great, with a clarity and accuracy of sound that belies their small size. They kid you into thinking you're wearing far more substantial audio apparatus…you're getting sound that rivals earbuds available at substantially higher prices… the sound is as impressive as earbuds can get right now."
Pocket-Lint, Recommended Award

"…if you value pure sound quality over having a check in every box on the spec-sheet, the UW100 are approaching ‘no-brainer’ status. In audio terms they’re high up among the most accomplished true wireless earbuds around – in every meaningful sonic respect, they impress. Detailed levels, dynamism, soundstage, tonality, attack, you name it."
TechRadar, 5 Stars, Editor's Choice Award

"…in terms of sound these true wireless earbuds deliver the complete picture...if you want as complete, as convincing and as straightforwardly enjoyable sound as this sort of money can buy...the Astell & Kern AK UW100 should most definitely be at the very top of your shortlist."
Tom's Guide, 5 Stars, Editor's Choice Award

"You'll want these super in-ears if knock-out sound is your number one priority…these wireless earbuds raise the bar."
T3, 5 Stars, Platinum Award

"For a first foray into the world of true wireless earbuds, Astell&Kern has done an amazing job. Full marks must go to the company’s engineers for leaving out ANC when they decided they couldn’t get a high enough quality sound…The sound is sublime…All in all, Astell&Kern has done a great job here and created a pair of true wireless earbuds that don’t make compromises."

Dedicated DAC

With its separate and dedicated AK4332, 32-bit high-performance DAC (Digital-to-Analogue Converter), working in tandem with Astell&Kern’s proprietary AMP technology employed in its award-winning DAPs (Digital Audio Players), the AK UW100 is geared for a clearer, more accurate and dynamic audio performance.

Latest wireless technology

To realise the AK UW100 leading wireless performance, the next gen, high-quality aptX™ Adaptive codec is supported, expertly adjusting the bite rate according to the wireless environment it is operating to reduce latency issues (it supports up to 24-bit audio at a bit rate of 420kps). Support for the latest Bluetooth 5.2 provides greater range and a more stable wireless connection.

Best in-class passive noise isolation

With an ergonomic and lightweight earbud design developed through countless simulations, the AK UW100 offers best-in-class passive noise isolation (PNI) to enable a truly immersive experience when listening to music in clamorous environments. Unlike generic Active Noise Cancellation that concentrates on blocking out low-frequency noise, PNI efficiently minimises unwanted ambient noise in the mid and high range.

Intuitive controls

For easy control on-the-move, the AK UW100 sports responsive touch controls for commands such as play, pause, skip track, volume adjustment, activating Ambient mode, answering calls and enabling voice assistant from a compatible device. A proprietary iOS and Android app also allows users to customise touch controls, ambient levels and various EQ settings, while support for Apple Siri and Google Assistant allows voice control.

Music for 24 hours

With the earbuds boasting six hours of battery life and a further 18 hours via the case (24 hours in total) users can enjoy music all day. With the convenience of wireless charging supported, the AK UW100 charging case also features fast charging, with a 10-minute charge providing an hour of playback.
