"Got a match?" ("Uh-uh")

"It's a fabulous party! . . . Look at all the fabulous people."

"You wanna dance?" ("Yes I'd love to . . .")

"Let's party a little bit." ("All right . . .")

I thought I would start my day by exploring the Hotel Bonaventure's ballroom exhibits, and on my way to the Westmont 2 room, where British company PMC was presenting the North American debut of their flagship Fenestria loudspeaker, I heard some unambiguously live harp music, played by the young lady in the photo, Isabeau Corriveau. A great way to start the day and one that emphasized the show's focus on music of every kind.

"Listen to that—that's what I mean by 'cone cry!'"

It was 1979. I'd been taking part in a blind listening test of loudspeakers organized by Martin Colloms (footnote 1) for the British magazine Hi-Fi Choice and, after the formal sessions had ended, had asked Martin to explain something I'd heard. A drive-unit's diaphragm produces cone cry when it resonates at a frequency unconnected with the musical signal it is being asked to produce; we had been using an anechoic recording of a xylophone, and one of the loudspeakers we'd been listening to was blurring the pitches of some of the instrument's notes.

It used to be on my commute that I'd see my fellow subway riders listening to music on their iPods with headphones from Beats, Bose, Sennheiser, Sony—and even, occasionally, from Grado. These days, however, iPhones and Android smartphones are ubiquitous, and while I still sometimes see a pair of Beats, many travelers now wear Bluetooth-connected Apple AirPods. I haven't bought a pair of AirPods, so I don't know how they sound, but at $159, I suspect they don't compete with "legitimate" headphones. Even so, I wondered if convenience trumps sound quality when it comes to listening on the move.
