Edit: Fair enough, I'm entirely incorrect as far as the headphone price point.
On the production side of things where quality super matters, you'll see the more expensive headphones for sure. But every single person in the last newsroom I saw rocked the 7506, and though I've moved on to more expensive headphones for programming and my music collection, I still miss my 7506s on occasion.
I don't think there's anything that comes close for ~$100 in terms of sound quality and comfort; you'd have to spend at least $300 for a real upgrade. And even then, there's an element of subjectivity.
But yeah, couldn't agree more. Price point.
Having listened to most and owning/owned for both studio and personal listening use some of the headphones that Marco reviews I can’t help but wonder if there is some bias going on with the music he reviews with or whether he actually does have very skewed hearing. Having been used to fine equipment and rooms whilst working in mastering suites, recording studios and I have picked up a preference for probably a certain type of sound but when auditioning and getting used to audio equipment I often test with a wide variety of sources that includes some music I don’t personally like but know quite well (such as country and western) as a reference to understand capabilities across the board.
Whatever ones thoughts it highlights the importance of auditioning oneself and getting to know something well (goes for speakers, rooms and headphones). It’s possible to do produce a good result using MDR-7506 or NS10s if you are comfortable with them and have the skill to do so.
It's like the NS-10's of the headphone world. Well-understood and consistent, while offering a great average, flat experience that translates well over the air.
