Earhorns!

Just what we always wanted: earphones that you can turn into speakers. Japanese firm Elecom's Earhorns (there's a subtle pun on "earphone" there that doesn't quite work in English) are your usual inner-ear speakers, but come with what are known technically as "squareish white plastic things" that use the (don't laugh) "Horn Load" format to amplify the sound on the same principle as the trumpet. Jam your earphones into them and, hey presto:
an Earhorn is born. They come in eight fruity colours and will set you back about Y3,000 ($28).
