There are a few fascinating features to the Bang & Olufsen A4 Speakers that make them a great improvement upon existing sound systems. Designed as a concept by Clément Puertolas, the devices have been engineered for increased convenience and sound pollution reduction.

Taking a flaring cylindrical form, each gadget is accented with a larger wooden ring that brings stability to it as it sits and provides a handle for easy portability. Because they are cordless, the amplifiers can be carried throughout the house, connecting to your smartphone, your tablet and your computer wirelessly.

Dome-shaped components within the Bang & Olufsen A4 Speakers project sound by focused parabolic reverberation and controlled diffusion, lessening the distance that your music travels. The devices are designed to be used up close and recharged effortlessly while resting on an induction panel.
