Rapoo has just launched a portable Bluetooth mini speaker that isn't much larger than a headphone ear cup, but nonetheless plays sound like any loudspeaker.
Called Rapoo A3060 Bluetooth 4.0 Portable Mini Speaker, it is a small cylinder, just 2.8 inches / 70.9 mm tall. It looks like a tiny little jar really.
There are controls embedded on the top, for volume control and track jump (next/previous).
There's even an integrated microphone, for taking phone calls.
And since this is a wireless audio device, there's also, naturally, an integrated battery in there somewhere (rechargeable obviously).
Rapoo A3060 Bluetooth Portable Mini Speaker has a price of $49.99. That's €37.30 according to exchange rates, but if sales do start in Europe at some point, the tag will probably be closer to €49.99. Silver, green, orange, yellow, blue and black are the available colors.
