I tested a living room full of cheap Ikea speakers against Sonos and Bose

Ikea's Kallsup Bluetooth speaker, priced at $10, is described as fun, colorful, and offering sound quality better than expected for its price. It features a simple design with a 2.75-inch plastic cube enclosure, available in pink, white, and yellow green, and includes two buttons and a small LED. The speaker can connect up to 100 units together, making it a convenient option for adding color and sound to spaces like a desk or a child's room.
