I've tried a lot of sets of headphones over the years, some even in the $500 and $600 price range, but always keep coming back to the SONY 7506 model. I know headphone preference can be somewhat subjective, but does anyone have a favorite they want to recommend? At one station, where I had a halfway decent budget, I gave the airstaff the option of picking something they felt sounded better than the SONY 7506. I provided models from Audio Technica, Beyer Dynamic, Sennheiser, and others. But still, even with the airstaff members, they too favored the SONY 7506 model.
