This stylish Bluetooth speaker has four features you won't find anywhere else

Teenage Engineering’s OB-4 is a Bluetooth speaker with a retro boombox look and surprisingly solid sound.

Its standout features include FM radio, a two-hour instant-rewind tape mode, and built-in ambient, noise, and metronome sounds.

Sampling and looping controls make it feel more like a creative audio instrument than a basic wireless speaker.

It’s highly portable and well built, though some surfaces are prone to scratches.
