Some years ago I bought a set of Sony MDR 7506 headphones for monitoring of sound quality when recording interviews.
I’m very pleased with the product. It didn’t cost all that much and the sound quality is excellent.
A Feb. 29, 2013 New York Times article about fashion headphones quotes an audio engineer named Jim Anderson:
“Mr. Anderson, obviously a sound purist, said consumers should look to the tried and true. ‘There are certain models of headphones that have lasted years and years,’ he said, citing the Sony MDR 7506 headphones, which cost $100, and are a standard model for audio engineers.”
