Astell and Kern AK UW100 True Wireless Earbuds

The Astell and Kern AK UW100 True Wireless Earbuds feature high quality Bluetooth and DAC chipsets, derived from A&K's digital audio players. With Knowles balanced armature drivers and aptX Adaptive low latency Bluetooth, the AK UW100s deliver an accurate and engaging performance.

The AK UW100, Astell&Kern's first fully wireless earphone, based on proprietary audio technology, provides uncompromising wireless Hi-Fi sound with no cables required. A rarity for True Wireless Stereo (TWS), the AK UW100 has a separate embedded high-performance 32-bit DAC as well as a Balanced Armature driver for accurately reproducing sound, allowing the delivery of precise, high-quality audio with no loss of detail.

The aptX Adaptive audio codec support for exceptional audio quality is the final flourish, ensuring the AK UW100 is ready for wireless Hi-Fi sound. Combining all these features with ergonomic design and best-in-class Passive Noise Isolation (PNI), the AK UW100 takes your listening experience to a dimension where only you and the artist exist.

The AK UW100 earphones use the unique amplifier and audio circuit technology from A&K’s digital audio players with the AK4332, a 32-bit Hi-Fi DAC, the AK UW100 reproduces sound on a whole new level compared to the BT-chipset-integrated DAC.

Moreover, it enables clearer and more accurate sound reproduction in all genres by adopting the Knowles Balanced Armature Driver, which is typically used in expensive IEM (in ear monitor) systems, instead of the Dynamic Drivers that are common in generic TWS systems.

The AK UW100 uses best-in-class Passive Noise Isolation (PNI) to immerse you completely in the music. When combined with the thoroughly tried-and-tested ergonomic design of the AK UW100, PNI is sufficient to reduce noise physically. PNI can efficiently cancel unwanted ambient noise in the mid and high ranges, as well as higher-pitched sounds, whilst retaining sound quality.

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.

AK UW100 features powerful wireless performance enabled by Premium Tier QCC5141, support for aptX Adaptive, Qualcomm's next-generation high-quality codec for wireless 24-bit sound quality and Bluetooth 5.2 support, for better connectivity than previous models. Through aptX Adaptive support, latency — the downside of Bluetooth audio — has been significantly improved.

With AK UW100, there are no worries about continuous playback time, one of the key features of TWS systems. The earbuds alone stay running for a minimum of 6 hours and up to 24 hours, so you can enjoy music all day without worrying about power. Alongside the convenience of wireless charging, AK UW100 also supports fast charging, so you can charge for 10 minutes to play for an hour.

Precise full-touch control is enabled so you can simply tap to switch between functions: Play Music, answer calls, adjust the ambient level and volume, and more.

Tap the left earbud three times to activate your smartphone's Voice Assistant function. Control music playback, make phone calls and more powerful smartphone functions with your voice.

Integrating a Voice Communication Package (VCP) from voice application specialist Alango, the AK UW100 enables quality voice calls. Based on special Acoustic Echo-Canceller and Noise-Suppressor technologies, the AK UW100 effectively reduces noise in a variety of settings and environments, ensuring call stability.

Install the exclusive app to access various functions and configure the device with ease. With the app, you can customize the touch controls, ambient levels, various EQ settings, and more.
