Astell&Kern delivers Mastering Quality Sound (MQS) as the ultimate portable audio source. The name Astell, meaning "Stars" in Latin, and Kern, meaning "Center" in German, reflects our belief that Astell&Kern is the center of music.

While advanced recording technology allows music performances to be captured in digital form almost exactly as they were performed, high-quality recordings are often compromised by inferior formats like MP3 or streaming services. With the MP3 format, convenience came at the cost of sound quality, compressing files to make them portable but degrading vocals, instruments, and the overall soundstage. Astell&Kern was created to address these issues and restore the original sound quality of music—Mastering Quality Sound—for artists, engineers, and professionals.

Our goal is to deliver natural, distortion-free sound that reveals the smallest details of the original recording. Astell&Kern allows you to experience live performances exactly as they were recorded, without any loss of detail.

Admired by music lovers worldwide, Astell&Kern has been featured in major audio exhibitions and is respected across countries, including the USA, China, Japan, the UK, France, and beyond.
