I use Samson SR850 wired over-ear headphones. They’ve got a big, chunky, old-school “don’t interrupt me unless you want to see this deadline missed” look and feel to them. And they sound good whether I’m listening to Chopin or Cannibal Corpse.

Beyerdynamic DT-770 Pro (80 ohm).

These have become a standard over-ear closed-back reference headphones for audio recording and production. Around US$150, extremely comfy and block a good deal of sound. They have a flat response, a good soundstage (wide feeling) and excellent detail. Add EQ for a more consumer-style sound. You wouldn’t want to wear them about town or during your workout. I put them on and disappear.

I’ve been using the Sony WH1000-XM3 for ~9 months now and they are absolutely worth the (high) price. The headphones are able to last more than a day on a single battery-charge, and the noise cancellation is ridiculously good.
