These retail at 300$ . I got them for 80$ here.  For the price i paid - they are extremely good. The sound is clear and neutral. The soundstage is good for a closed can, the bass is punchy and tight, the mids are extremely good with lots of details. although I find the treble to be a bit lacking for my taste. other than that - they sound amazing. they can be easily driven with an ipod or a phone. they also have an inline mic. if you get these under 100$, it's a steal. even if you get it under 200$ - they are really good.

They sound great and are better than the px 100ii's.

One of the best sounding headphones I have ever owned.

Very good product for the price !
