So many people have iPods and other portable music players these days. Sure, they're pretty much hands-free, but not everyone cares for earbuds.
I saw a man downtown the other night, walking down Michigan Avenue. On his shoulder he bore a music-playing device the dimensions of which approximated 12" x 8" x 3". It was a wireless marvel! No cumbersome wires to tangle, nothing wedged hotly and waxily into his ear canals, and no over-loud sound waves aimed directly at his eardrums, posing a risk of hearing damage. Furthermore, this player allowed him to continually improve the endurance of his shoulder and arm muscles.
Keep your eyes out for this exciting new trend in portable music!
