Astell&Kern XB10 Bluetooth receiver and headphone amp

While the AK XB10 is a device that wirelessly transmits audio data from smartphones via Bluetooth,
it is quite different from conventional Bluetooth devices, in that it supports the aptX™ HD Bluetooth codec.

Just as the display resolutions of televisions evolved from standard to high-definition to 4K ultra-HD for sharper
image quality, we are now in the era in which Bluetooth now supports 24-bit audio resolution.
24-bit HD audio that was simply not possible with previous Bluetooth technologies
can now be fully enjoyed with aptX™ HD.

Typically used in professional broadcasting, the original aptX™ audio codec is widely used
for 16-bit near-CD quality sound.
The benefits of the aptX™ codec include superior compression, low computational cost,
and low transmission delay.

Launched in early 2016, the next-generation aptX™ HD codec is capable of transmitting up to
24-bit/48 kHz audio that is faithful to the original audio file.

* Devices connected to the AK XB10 must support the aptX™ and aptX™ HD codecs for 24bit audio playback.
