The AK XB10 allows for convenient wireless listening to a sound source such as a smartphone through high-quality bluetooth technology. Inheriting the design language of a design inspired by light and shadow and developed by Astell & Kern, it embodies the scattering light of twinkling stars. The best feature is the easy touch control of the product movement by means of the D click side at the upper part of the product that is asymmetrically divided into four parts. It is the first wearable device of the AK series, which increased user convenience with a new detachable clip design using the tension of stainless steel.
