JBL MF-07 Mini Bluetooth Speaker with Carry Loop

Palm-sized, wrapped in speaker mesh, with a bright orange loop moulded into the shell so it clips to a bag strap or a belt hook and goes wherever you are going. Three controls on the face — volume down, play, volume up — and a power button on the top edge. That is the whole interface, which is the right amount for a speaker this size.

It comes in black, red, purple, green and camouflage, all sharing the same orange loop. Twelve dollars puts it in the bag-and-forget category rather than the hi-fi one, and it is honest about that.
