A small Bluetooth speaker on its own sounds thin, and a big one takes up space you don’t have on a desk or shelf. This bone conduction speaker gets around that: stick it to a wooden door, a cupboard or a steel surface and it vibrates that surface, so the whole panel becomes the speaker. This exact unit was filmed on camera and inspected before listing, which is why it costs less than a new one.
The 24-bar RGB ring around the top pulses with the beat, so it doubles as a mood light for a room or a small party. It charges over USB-C, the same cable as most phones.
The honest catch: there are no volume buttons on the speaker, so you set the volume from your phone. Hard, flat surfaces such as steel or solid wood sound best; soft or hollow ones sound weaker.
