[ The obvious then occurs to Shinjiro. She probably has no idea what he's talking about. ]

... Um. Right.

You'd have a small machine, like the size of this phone, or smaller. Or, guess you can put music on these fancy phones we're givin here. They've got 'nough space.

Then, you plug the headphones into 'em. They go over your head to sit on your ears, or they're smaller and hook 'round or actually fit into your ear. Tiny little speakers, so only you can hear th' music.

[ Shinjiro shrugs. ]

Not really. Sometimes, if you get one of those songs, that ain't gonna leave your head, I hum it a bit. Can't help that, right?

But actual singin? I can never really remember the words, anyway.
