These are the best-tuned Sennheiser to date at any price to my ears. The tuning is really, really good and they stage fairly wide as well. I’d say these are the best bang for your buck and you’d have to spend more than double their price to get anything better. I’d say these drastically amplify the concept of diminishing returns.
I’ve heard the 600, 650, 6XX, 700, 800, 800S, 660S, 660S2, 598, 599, 569, 560S, Neumann NDH30, and 490 PRO, and I’d take these over all of them due to their comfort, staging, tonality/tuning, and PRICE. These sound clearer than the 6x0 line but are somehow even smoother to my ears. And I’ve always been more of a 650 over the 600 kind of guy.
I’m not saying I haven’t heard better, but these make me feel like I overpaid for them…
Very nice job Sennheiser
I may buy a second pair just for backup. These need some more love!
