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.
