As Seen On TV Video • keychain speaker
Boom Cube is a tiny speaker, just one inch square, that produces big sound when connected to an iPod, smartphone, tablet or laptop. Back in the 1980s, you had to carry an enormous boom box on your shoulder in order to blast your cassette mix tapes at maximum volume to an unwilling audience. It also cost a fortune to keep them in D-size batteries. If you had one of those new-fangled Sony Walkmans, you could enjoy your music privately, but without a way to share your superior musical tastes with strangers on public transportation.
