The Culsup is lightweight but solid feeling, a plastic box with speaker holes on one side, a USB-C port on the back for charging, and two buttons on the back for power, playback, and a small LED status light for pairing. It was instantly charming, and not just because it was so adorable; Whatever action you perform on it, it produces whimsical man-made sounds – like a rattling or whooshing sound. The speakers use Bluetooth 5.3 and up to 100 Culsup speakers can be synchronized simultaneously by creating a proper sequence of long pressing the play button between them.

By pairing a few together, the Culsup Cubes were able to fill the room with sound better than you expected – not tinny or dull. They certainly don’t put out much bass, nor would I expect it to at this size and price.
At first glance, my only real criticism stems from Ikea’s decision to put only two buttons on the box: a Play button and one embossed with the Bluetooth logo. It’s not clear to me why you would long press the play button instead of Bluetooth to pair the speakers together, nor is it clear how they are locked, or even if you can do it manually. However, if you wait long enough, the speakers time themselves out.
