Bone. Horn. Ride. The jokes write themselves.
This is the Horn Bike iPhone case from Bone, and you can probably guess from the name exactly what it does. Your iPhone 4 slides into the silicone sleeve and a Velcro strap secures it to the handlebars of your bike. So far, so ordinary.
The neatness comes from the ‘horn' part, which is in fact a horn speaker that channels the sound from the iPhone's speaker forwards and at the same time stretches it out, making it up to 13dB louder.
