Summary: Well controlled sound, just like most other Sennheisers. Those headphones are reasonably efficient. Most protable players should be capable of driving them to unhealthy level. Before I get more specific I need to state that I listen to mostly classical music and latin jazz.
Pros: Lightweight, comfortable, not very expensive. Decent midrange.
Cons: Nowhere near as good as the PX100. I have owned the PX100 for over 3 years, having 2 pairs in that time used everyday. These are nowhere near as tight and clear. Low bass is very muddy, smeary and not as "tight". I recieved a gift certificate and these were the exact amount plus shipping of the c...
Summary: Great set of headphones. They are lightweight, comfortable, yet solidly built. The padding on the headband makes all the difference in the world. Gives the listener the ability to listen comfortably for hours.
Like other reviewers have said, you will hear music like you've never heard before.
Summary: I have the on-ear open Sennheiser PX100 headphones which have a good sound quality. But, at times I need a closed ear design to help block outside noise. So, I bought the PX200 headphones. The sound coming from this headset is extremely tinny and shallow. I returned them for a refund.
Summary: Great sound, love the compact case too, very handy. Sound is very nice, only wish they had more bass to them. tried a set of bose on in a best buy and they blew these away but this was in my price range. .
Summary: The px 100 has foam pads, and quite comfortable. The px 200 has leatherette covered rings that sit on (not around) your ear. Over time, makes my ear numb. I can not have them on more than an hour or two. I tried them with my digital piano..
Pros: Pretty good noise isolation. Foldable /portable design. The sound is better than your average cheap mp3 headset. Nice high-end.
Cons: Noticeably worse bass and soundstage than the cheaper px 100. To my ears, sounds pretty thin. Supposed to have excellent "kraftvoller bass"... not. IMO not worth the extra money. It was especially bad with my iphone. I am saying goodbye to these.
