Customer feedback:

1. I was looking for phones that would pack plenty of punch without sacrificing any of the qualities of their full-grown, ostentatious siblings. Anyone who's even moderately serious about headphones knows that the smallest improvements come at a price. In the case of these phones, the cost is easily justified. I've compared them with several portables in the $5-10 range along with some full-sized models weighing in at $50-100. Conclusion: these are worthy of being your "front-line," and perhaps only, pair of phones. They're up to the task of distinguishing each of the instruments in a jazz rhythm section or reproducing the spacious quality of an entire string section. The treble is distinct and "alive"; the bass is, if anything, more than I require (and the PX 200's are supposedly the bass-heavy models). Comfort? They feel the same as any $2 pair of portable headphones--until the music begins, at which point "wearability" is not even an issue.

2. The PX100s are small, unobstrusive phones. They're suited to portable music players (portable CD and MP3 players), as they are relatively efficient and drive well for the most part. They are small and thin, so you won't look like a complete geek or goofball wearing them in public, and they fold up cleanly and could easily fit in a shirt or pant pocket. They also include a carrying case. The build feels flimsy, but they are actually far more durable than one would imagine. The cord is thin, so beware snagging it too sharply, and short (these are not for use with a home system). They are also extremely comfortable, with a large "sweet spot" and light weight.
