PDAToday takes a detailed look at a selection of several Sennheiser headphones; the Sennheiser MX500, PX200, and PX250. Here's a taster:

The Sennheiser PX200 is a nice, mid-range folding headphone. With features like a folding design for portability and padded ear and head cushions for comfort, the PX200 is easy to carry and use. The single point pivot of each speaker makes the PX200 easily adjustable for most head sizes. The PX200 is light weight and the speaker cushions make it comfortable to wear, although my ears get a little sore after more than 1 hour since the cushions rest on top of the ears (due to its compact size) rather than on the side of the head. I previously purchased a PX100, which I still use today, and the PX200 is a nice upgrade in performance.

The PX200 does not come with any accessories other than a hard shell case to protect the headphone once it is folded. It is very protective, good for traveling, and managing the cable. Unlike the MX500, the PX200 does not have an inline volume control.

Since the ear cushions do cover most of the ear, the PX200 provides some noise isolation, but you can still hear the noise around you. The power efficiency seems to be a little better than the MX-500, so you do not need to keep the volume level as high for a comfortable listening experience. The PX200 features a lightweight (60g) design with Neodymium magnets for low distortion, Sennheiser custom diaphragms for good response and reproduction, 3.5mm stereo plug, 1.4 meter cable, and dynamic drivers with 32 Ohm impedance, 115 dB sound pressure level, 1% total harmonic distortion, and a 10-21,000 Hz frequency range. All sound ranges are good with a "solid" quality at all frequencies. The bass range is very good with a deep, "tight" sound. The mid range is also very good, while the high range is good, but seems to lack a fast response to quick note changes.
