I didn't have a ton of money and wanted something portable so I bought the Sennheiser PX100 in 2007 after researching reviews and comparisons to the other makes of this headphone (the noise-canceling one and such).
I've run through two pairs and I'm on my third pair. I have to take better care of them because the headphone jack keeps getting messed up. I'd look into more expensive headphones, but each time I have to replace them I only have enough money to buy a new pair of PX100s so since there's nothing better in that price range I just order them off amazon.
Don't be fooled by the image. That's a brand new pair. Once the pads wear, they contour to your head naturally and you probably won't even feel like you're wearing them.
