Under the competitive influence of two gadget-obsessed colleagues I bought a pair of Bose noise-cancelling headphones for listening to music and DVDs while flying. They're quite extraordinary. Supposedly, they adjust to address and cancel whatever ambient noise is around you, then deliver your audio. Whatever it is they do, it works — to the point that if you just power them up in a crowded exhibition hall, you make your head an oasis of soothing quiet.
(To earphone novices, noise-cancelling earphones rely on battery power to generate the noise-cancelling effect.)
Turns out, Bose headphones also work to cancel out the sounds of nearby snoring. Sounds you might otherwise compare to a snorting bull about to flatten everything in his path are dimmed down to resemble the purring of a big, contented cat.
The only problem I've found with wearing the Bose headphones to bed is that I have to sleep on my back. But at least I'm sleeping.
