Astell & Kern – UW100MKII True Wireless
The AK UW100, embodying Astell&Kern’s commitment to delivering authentic music in the realm of true wireless earphones, garnered significant attention for its distinctive design and unparalleled sound quality. Building on this success, Astell&Kern has dedicated continued efforts to research and development, culminating in the introduction of the AK UW100MKII – a premium True Wireless Sound (TWS) solution that effortlessly brings the ultimate audio experience to any place and time.
Next-level True Wireless Sound
Setting the AK UW100MKII apart is its integration of a High Resolution 32-bit Digital-to-Analog Converter (DAC), a feat challenging to achieve in the TWS format. Complemented by a full-range Balanced Armature driver, the AK UW100MKII ensures precision sound, delivering an outstanding Hi-Fi experience even in the wireless domain. Bolstered by best-in-class Passive Noise Isolation (PNI) and aptX™ Adaptive, along with an ergonomic design and cutting-edge high-resolution codecs, it represents a pinnacle in True Wireless Sound technology.
The AK UW100MKII’s internal circuit design has been further refined, incorporating digital circuit separation to reduce noise and introducing a new circuit structure for a more robust connection compared to its predecessor, the AK UW100. The optimization of electric currents, coupled with adjustments to the position of the Balanced Armature driver and a redesigned acoustic chamber, extends continuous playback time to an impressive 9.5 hours and provides a maximum playback duration of 29 hours. This ensures that users can indulge in Hi-Fi sound immersion at their convenience, anytime and anywhere.
Advances for more complete wireless sound
Astell&Kern has long adhered to the fundamental principle of reproducing sound as true to the original source as possible.
The AK UW100MKII, a true wireless earphone built on our proprietary audio technology, delivers uncompromising wireless Hi-Fi sound without the need for any cables.
A rarity in the realm of True Wireless Stereo (TWS*), the AK UW100MKII features a separate embedded high-performance 32-bit DAC and a Balanced Armature driver. These components work together to accurately reproduce sound, ensuring the delivery of precise, high-quality audio without any loss of detail. The final touch is the support for the aptX-Adaptive audio codec, ensuring exceptional audio quality and making the AK UW100MKII ready for wireless Hi-Fi sound.
Combining all these features with an ergonomic design and best-in-class Passive Noise Isolation (PNI), the AK UW100MKII elevates your listening experience to a dimension where only you and the artist exist.
A New Design for Enhanced Perfection
Astell&Kern has elevated the acclaimed TWS design of the AK UW100 to perfection with the AK UW100MKII, presenting the epitome of Hi-Fi sound that reflects the pinnacle of Astell&Kern’s technological prowess and expertise.
In pursuit of audio excellence, the AK UW100MKII introduces a refined positioning of the Balanced Armature (BA) driver, now situated towards the inner ear to deliver finer audio details with enhanced precision. The acoustic chamber structure and mesh size underwent multiple redesigns, meticulously aligned with the new BA driver position to achieve optimal sound output. Numerous iterations were undertaken to minimize sound diffusion, resulting in a more delicate and dynamic performance and a heightened expression of rich high frequencies.
The AK UW100MKII stands as a testament to innovation, featuring unrivaled 32-bit DAC technology within completely wireless earphones. Leveraging the AMP and circuit technology unique to Astell&Kern, it facilitates the separation of digital components and analog circuits in the wireless earphone. This groundbreaking design not only achieves a further reduction in noise compared to its predecessor but also ensures clearer sounds with enhanced separation levels, setting a new standard for wireless audio excellence.
The Best Choice for Pure Sound – Enhanced musical immersion
The AK UW100, its predecessor, set a benchmark with the highest-level Passive Noise Isolation (PNI), positioning itself as a true Hi-Fi True Wireless Sound (TWS) solution that not only eliminates noise fundamentally but also excels in noise-canceling performance without resorting to Active Noise Cancellation (ANC) and potential sound distortions.
The AK UW100MKII continues this legacy, providing users with a superior musical immersion experience through its outstanding sound technology and the highest-level PNI technology. In contrast to ANC, which is not a prerequisite for achieving reduced ambient noise and increased musical focus, the AK UW100MKII relies on the proven ergonomic design and the robust capabilities of PNI to physically reduce noise.
Diverging from generic ANC that primarily targets low-frequency noise, the efficiency of PNI extends to cancelling unwanted ambient noise across mid and high ranges, including higher-pitched sounds. Remarkably, the AK UW100MKII’s noise-canceling prowess rivals that of ANC even for low frequencies, and its unique feature is the retention of sound quality, achieved by attenuating noise through the structure of the earbuds rather than relying on software.
Crafted through extensive simulations, the AK UW100MKII’s best-in-class PNI capability empowers users to escape disruptive ambient noise, creating an immersive experience where only the listener and the artist coexist. For those who wish to hear ambient sounds, a simple tap on the left earbud activates ambient mode, with the flexibility to switch between four ambient modes through tapping or the dedicated app.
Continuing the joy of music
Astell&Kern has undertaken a comprehensive redesign of the power system in the AK UW100MKII, a crucial factor in True Wireless Sound (TWS) performance. This redesign aims to significantly extend playback time, a feat achieved without compromising the paramount aspect of sound quality. Through innovative internal design and meticulous current optimization, we’ve not only maintained the earbud size but also dramatically reduced the cradle size, resulting in a substantial increase in playback time.
Now, you can revel in the music all day long without the concern of recharging with the AK UW100MKII. Offering approximately 9.5 hours of continuous playback and up to an impressive 29 hours of total playback, you’ll never miss a beat with this advanced TWS solution.
Adding to the convenience, the AK UW100MKII supports wireless charging, providing a hassle-free charging experience. Additionally, for those moments when time is of the essence, fast charging is at your disposal – just a 10-minute charge yields an hour of playtime, ensuring that the music keeps pace with your dynamic lifestyle.
Elevating the Bluetooth experience to premium standards
The AK UW100MKII is tailored for exceptional Hi-Fi sound quality, empowered by the formidable Premium Tier QCC5141. With support for aptX™ Adaptive, Qualcomm’s cutting-edge codec for wireless 24-bit sound quality, and Bluetooth 5.2, the AK UW100MKII surpasses its predecessors in connectivity and audio excellence.
The integration of aptX™ Adaptive is a game-changer, addressing the latency concerns inherent in Bluetooth audio. This support not only significantly improves latency but also dynamically adjusts the bit rate based on content and wireless conditions, supporting up to 24-bit sound through a bit rate of up to 420 kbps.
The AK UW100MKII goes a step further with Qualcomm True Wireless Stereo Plus* mode, minimizing transmission delay by independently sending signals to each earbud. This advancement ensures a seamless and immersive audio experience, free from disruptions.
