Ferrofluid Sound-Reactive Display, Bluetooth and AUX, ABS and Glass
The Day Birch ferrofluid sound-reactive display houses black magnetic ferrofluid inside a clear glass sphere set in an ABS body, and the fluid pulses and moves in direct response to audio playing through the Bluetooth or AUX connection. The included AUX cable and USB-C charging cable mean both connectivity options and power are ready straight from the box. As the audio plays the display also lights up, adding a glow to the fluid movement that makes the reaction visible from across a room.
The 8 to 10 hour battery life on a full charge covers extended listening and viewing sessions without needing to stay plugged in, and the included handheld magnet adds another way to interact with the ferrofluid directly. At 4.2" (10.6cm) x 3.9" (9.8cm) the device sits on a desk or surface without requiring a dedicated display stand, and White, Black, Wooden, and Grey colour options keep the ABS body adaptable to different surface and interior combinations.
