Comfort issues being what they are (and they are real, but not insurmountable, at least for me), the performance of these babies is ONLY limited by the equipment used to drive them, and the quality of the recording. Period.

Ipods need not apply.

I've got mine running from software (Foobar2000 with digital eq, four-channel converter, and Dolby surround headphone listening room wrapper plug-ins) to a high quality pc soundcard, then through a OP2132 OpAmp, and I'm still not convinced I'm getting everything I can out of them. Heart's "Dreamboat Annie" disc never sounded better.

I can't stress enough that whether you call it a virtue or a weakness, these phones WILL NOT lend a faux-audiophile sound to run-of-the-mill gear, like some modern phones will. If you haven't spent a lot of time/research and/or money on your equipment purchases, good luck with these.

They are built to last, if that helps.

Enjoy at a safe decibel level ;-]
