For sale is a Beyer 770 Pro 250-ohm. Purchased in April, have about 100-200 hours on them. I enjoy them, I just received my Argons recently and ended up preferring those.

I've always described this headphone as an absolute rock and heavy metal monster. Excellent bass extension, crisp and detailed highs, and like a good closed-back, it keeps a lot of internal sound in and blocks a lot of external sound out. Plus it's built like a tank and extremely comfortable. Probably my most comfortable closed-back.

This is the 250-ohm variant, so an amp is required, and I think these need to be EQ'd to really get the most out of them. But they respond well to EQ, and once you dial them in, you're ready to rock and roll.

Cosmetically and functionally like new. No box. Missing the original 3.5mm-1/4" adapter, but comes with a generic one.
