Sony 7506. Have a single pair that I used for countless symphony recordings, mixes, and just using around the house when I want to hear something special. Replaced the ear cups many times, and perhaps they aren't as bright as they were 20 years ago, but higher frequencies start dropping off a man's hearing around age 30. Great for using when reference/clarity matters, but will cause some fatigue after a couple of hours for me. Cheapo $20 earbuds with a rechargeable case have changed the game for me, I wear them everywhere.
