Portable Bluetooth speaker with up to 24 hrs of battery life. Even the heaviest beats are easy to carry. Beoplay A1 is small enough to sit in the palm of your hand, it weighs only 600g and because of its shape (with no protruding buttons or legs) it is easy to store in your backpack or slip into a pocket. So you can take it anywhere you go and enjoy Bang & Olufsen Signature Sound.
