Swedish furniture giant IKEA has launched a tiny, cube-shaped Bluetooth speaker that can link with up to 100 identical units to create a massive sound system.

The ‘Kallsup’, launched at CES 2026, measures just 2.75 inches on each side and weighs little more than a handful of coins.

Available in white, hot pink and lime green, the speaker includes two small control buttons on top for pairing and playback.

While compact, the speaker packs enough punch for casual listening. It runs on an integrated, replaceable battery, offering roughly nine hours of playback at half volume, and charges via USB-C. Bluetooth 5.3 ensures stable connections, while pairing multiple units doesn’t require an app – just a few button presses.

Individually, a Kallsup covers a small room, but the fun comes when you multiply it.

Pair up to 100 units to fill larger rooms, outdoor areas, or even multiple spaces in a home, making it ideal for gatherings, events or pop-up venues. IKEA describes it as a modular sound system, emphasizing flexibility over raw bass.

The Kallsup will go on sale in the US in April for just $10, with Australian expected to be similarly low at around A$20. IKEA hasn’t confirmed an Australian release yet, but the speaker is likely to arrive in local stores later this year.

The launch follows IKEA’s recent expansion into audio, including the Solskydd circular wireless speaker and Kulglass lamp speaker.
