Description The Aura Studio line is Harman Kardon’s “dome-shaped” Bluetooth home speaker series, combining 360° omnidirectional sound with a visually striking transparent dome and ambient lighting effects. It’s designed more as a home-stationary speaker (not portable), meant to sit somewhere prominent and be seen as much as heard. Later versions (like Aura Studio 4) emphasize eco-friendly materials (recycled fabrics, aluminum, plastics) and improved lighting themes.
