KALLSUP

Reviewers mostly praise the IKEA KALLSUP for its surprising audio performance in a tiny, artistic cube. It delivers clear, non-distorting sound at high volumes while looking like modern art rather than a cheap gadget. However, as a simple Bluetooth speaker, it lacks advanced features like app control or voice assistants, and the ability to pair up to 100 units is intriguing but untested in real-world scenarios.
