The Harman Kardon Aura Studio 4 Bluetooth speaker follows the design language of the manufacturer’s Aura product family. Both the transparent dome and the 360-degree layout are inspired by the predecessor models. Shimmering through more than 300 crystals arranged in a diamond pattern in the dome of the Aura Studio 4, the light takes on different colours and appears to dance to the respective rhythms. “The synchronisation of light and sound enables listeners to submerge themselves in the music with all their senses,” said the jury, describing the immersive sound world. “The wide sound stage with powerful bass” strengthens this effect.
