Designed to be used onstage by musicians monitoring their sound and mix, in-ear monitors (IEMs) such as the new Westone 3 are great in situations where you want to hear nothing but the music. They're small and portable, and their high efficiency and easy impedance load mean they work well with portable players. IEMs are better than electronic-feedback, noise-reducing, closed circumaural phones at blocking out airplane engine noise and annoying neighbors who want to chat. They're also more compact, sound better, and don't require batteries.

For a hobby based on science and technology, audiophilia has more than its share of unscientific elements. That's not necessarily a bad thing; not all of those elements are obvious snake oil, and there's more than science to creating—or re-creating—a musical experience. Still, for the more technical-minded it's a little disconcerting that even the most basic distinctions, such as why two CD players sound different from each other, are hard to explain using technical measurements and simple scientific concepts.

In New York and other major cities, I understand, bus accidents are a real problem. Buses turn right and failing to yield to pedestrians. Clueless pedestrians walk in front of buses. I haven't seen any statistics, but I'm guessing that in this era of cell phones and iPods, the problem has gotten worse: not only do such devices distract you, they make it harder to hear warning signs—such as the sound of a municipal bus bearing down on your ass.

The Rega Couple interconnect ($150/1m pair) comes in a plastic pouch rather like a Ziploc veggie bag—just the pouch and a printed card. How much could the packaging cost? Ten cents?
