Silver Plating Shield Can

Astell&Kern products apply shield cans so that noise and electromagnetic interference, which occur when the countless parts are in operation, do not affect the audio block.

The SR25 MKII has taken it a step further by applying highly conductive, hyper-pure silver plating on the existing shield cans for perfect shielding that provides excellent audio performance.

Excellent Continuous Playback Time

No need to worry about battery life. The SR25 MKII can play continuously for 20 hours with just one full charge, thanks to its optimized, energy-efficient circuitry.

Enjoy your own personal musical performance anytime, anywhere with the SR25 MKII’s extended playback time and its portability.

Wireless Hi-Fi Sound Through BT Sink

The newly introduced BT Sink function connects the SR25 MKII to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker. Music from an external device, such as a smartphone can now be played back in high-quality on the SR25 MKII using the BT Sink function.

RelpayGain Automatically and Uniformly Adjusts Playback Volume

ReplayGain, which adjusts sound sources with different volumes to an identical level, has been applied. Now, enjoy your own playlists seamlessly through the ReplayGain feature on SR25 MKII.

AK File Drop to enjoy wireless transfers

The new AK File Drop function in the SR25 MKII makes files transfers easier and more convenient. Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network. Music file management is now possible with a cableless, wireless solution.
