Crutchfield Customer Review (What's this?)
Excellent sound for the price. I have compared these both with my main speakers and my main headphones (Sennheiser HD 555, an over the ear design) and they compare very well. Bass is excellent, and I "base" that on bass drum and organ music as well as electronic bass. I found the mid-range and treble slightly shrill, but not offensive. Considering that the speakers cost about $1500 and the reference headphones about $250, the PX 100s are an incredible bargain. Comfort is pretty good; my outer ears start to feel the pressure after an hour or so, but I have listened for 2 hours without undue discomfort. I suppose this is inherent in the on-ear design. Although they have an "open" design, which does not isolate either incoming or outgoing sound, my wife has slept soundly with her head on my pillow while I was listening. They are reasonably compact when folded and come with a cloth pouch for transport and fit nicely in a jacket or briefcase pocket.
Pros: Bass response, comfort, compactness
