In the past few years, we have covered plenty of cool ferrofluid toys here. The Iceberg Crystal Speaker is also worth a look. It is a pyramid ferrofluid Speaker that visualizes your music while delivering rich sound. It has a transparent design, so you can see the “iceberg” inside.
This Bluetooth 5.1 speaker has a 25m range. It comes with 3 full range speakers and 2 woofers. Iceberg Crystal Speakers are ready for stereo pairing. They double as a gorgeous desk lamp. You can find out more here.
