Astell&Kern KANN High-Fi Digital Audio Player (DAP)


Request A Price Match

The KANN is a no-fuss, mid-range portable that simply delivers on what matters most: unbelievable (and wireless!) sound. 

Four Output Options

The KANN features balanced and single-ended headphone outs and balanced and unbalanced line outs. What this means is that you can optimize it for any listening experience: headphones, home theater system, car stereo, and more. 

Wired(less) For Sound

Why does listening to high-def audio require immobilizing our phones, laptops, and tablets with cables? Shouldn’t our mobiles be mobile? With Bluetooth 4.0 and WiFi support, the KANN will set your mobile free. 

Simply Pure Sound

With a signal-to-noise ratio (SNR) of 120dB, total harmonic noise plus distortion (THD+N) at 0.0005%, the only sound the KANN produces is pure music, plain and simple. 

Stellar Sample Rate 

Simply speaking, the higher the sample rate of a song, the better quality the music. A CD’s sample rate is 16bit/44.1kHz. The KANN can play up to 32bit/384kHz. That’s *checks notes* a lot better. Warning: your pleasure center will explode. 

The Portable That’s Actually Portable

Why do so many modern DAPs feel like lugging a can of soup in your pocket? It’s because they’re as heavy as a can of soup. The KANN, on the other hand, is actually portable. At 4.56” and 9.8oz, it’s guaranteed to fit inside most pants’ pockets, plus purses, backpacks, and even arm bands. But just because it’s smallish doesn’t mean it skimps on storage. A combined 768GB of memory ensures that no track is getting left behind. 

Open App Service 

With Asterll & Kern’s Open App Service, users can install APK music streaming apps such as Tidal, Spotify, Pandora, Amazon Music, Apple Music, SoundCloud, and more to their devices. There’s an ocean of music out there. Open the (streaming) floodgates!
