ShawnSmith, take a look at all the cans headphone.com offers. I would recommend the DT770's, but their may be other options available to you on the site. I personally own the Sony 7506's and they are closed, offer good sound (no amp required) and are built to last. I've had my pair for 5 years and they are still cranking like the day I bought them. The pads can be changed out to velour pads which gives them some great comfort for long listening sessions. Although, the cord can sometimes drag the left earcup down a little too much for me. I found the headband on the DT770's to be a little too short (the cord was on the short side too, from what I recall)...I had to remove the leather padding on the headband to get enough space to fit my noggin in there (I owned an older version).
Evil Taper, how's the headband on your DT770's? I know your model (DT770-80) was re-modeled a bit compared to the version I had (DT770-250). What about the cord? Is there more give with it? I remember mine being coiled up a little too tight.
