Small size. Serious sound.
With the largest woofer in its class, Beosound A1 delivers dramatically deep bass. Not to mention clarity that lingers in the air, and a presence that fills any space – all wrapped up in a pack-friendly form.

Power that powers on
The best moments should never be cut short. With up to 24 hours of playtime, Beosound A1 lasts as long as the best days do.
Clear everywhere. Heard anywhere.
Whether you’re taking calls from the home or the middle of nowhere, a three-microphone array ensures your voice cuts through – sharp, clear, unmistakable.

Ready to connect
Press play, slip away. With Bluetooth, Microsoft Swift Pair, and Google Fast Pair, Beosound A1 connects instantly and holds strong. Keeping your soundtrack seamless and uninterrupted.

Double the sound with a stereo pair
One Beosound A1 fills the space. Two take it over. Enjoy stereo sound that makes every moment bigger, bolder, and more immersive. With stereo pairing, you can even connect across generations – pairing a Beosound A1 2nd Gen with a Beosound A1 3rd Gen.
Sound you can feel
Some things just feel right. The pearl-blasted aluminium, the soft leather strap, the 2173 precision-milled holes under your fingertips. With almost a century of craft behind it, Beosound A1 is more than a speaker – it’s an object of art. And the best part is the size: perfect for any pack-and-go adventure.
