Astell & Kern UW100: Knowles BA Driver and Premium Tier QCC5141

Astell & Kern, the Korean reference mobile audio brand, has unveiled its first fully wireless earphones, the UW100. The sound here is provided by Knowles full-range armature driver. Electronics – to match: the novelty involves a 32-bit AKM AK4332ECB DAC and a Bluetooth 5.2 chip. As a result, Astell & Kern promises future owners of the UW100 “the best wireless sound you’ve ever heard“.

Passive Noise Isolation (PNI)

The active noise isolation system in the Astell & Kern UW100 was not used: engineers preferred to use passive noise isolation, and they claim that this works no less efficiently and more comfortably. And there is a mode of listening to the environment, and not in one, but in four modes.

Premium Tier QCC5141 & Bluetooth 5.2

Bluetooth functions in the UW100 are provided by the Qualcomm QCC5141 chipset with support for the aptX Adaptive codec – in the UW100 you can listen to 24-bit quality audio. Qualcomm True Wireless Stereo Plus minimizes latency.

Each earbud works independently, and the touch control functions are shared between the right and left earbuds – part on one, part on the other. In addition, the Astell & Kern UW100 supports Multi-Pairing and Multi-Point functions with connection to multiple devices at the same time.
