If you spend a lot of time on planes, do yourself a favor and invest in a set of Koss Spark Plug earphones for your portable music player iPod nano; they work a heck of a lot better than any of the active noise-cancelling headphones I’ve seen and won’t set you back anywhere near as much as the upmarket Shure and Etymotic brands, the marginal benefits of which will be drowned out by the jet engine roaring a few dozen feet from your head anyway.
I just wish I hadn’t paid $19 at Best Buy on Sunday for my pair.
