Agreed. The MDR-7506 is a "studio standard" for reference/monitor headphones in pro audio and video. The frequency response is not "enhanced" at the low end like the Beats and many other modern headphones. I don't think the curve is really flat- they always sound a little bright to me (thought in that hear-more-detail sort of naturally pleasant way), but they're definitely more flat than the Beats. The 7506 is like $90. The V6 has the same drivers, but doesn't have a gold plated plug (seriously). I got my V6s refurbed for $50. The closed earpads passively block external sound pretty well, and they're relatively comfortable. They don't come in green or pink, but they sound good, are still made with some metal parts for durability, and they're way cheaper than Beats.
