Hey, just catching up on this thread. I totally get it—the Sony MDR-7506 Professional Large Diaphragm Headphone is iconic for tracking but it's WAY too bright for 4-hour mixing sessions. Honestly, it gets fatiguing fast. I was kinda disappointed with some of the higher-end closed-backs lately, like the Sony MDR-CD900ST Monitor Headphone; they're great but importing them is a total pain and costs way too much for what they are imo. If you want a FLAT sound without spending a fortune, ur best bet is probably the Sony MDR-MV1 Open Back Reference Monitor Headphones. They’re usually around $350-$399, which is a lot, so I’d honestly suggest waiting for a B-stock deal or a holiday sale to save some cash. If that’s too much, look for the Sony MDR-7510 Professional Studio Headphones. They’re discontinued but you can find them used for under $100. They have a much smoother top end than the 7506s. Just be cautious buying used... sometimes the drivers are worn out. gl!

Like you mentioned, Sony MDR-MV1 Open-Back Reference Monitor Headphones beat Sony MDR-M1 Professional Reference Closed-Back Headphones for imaging, tho they're pricier. MV1 is WAY flatter. It's the best mixing choice.

> I’m looking for something with a much more neutral frequency response and better spatial imaging to ensure my tracks translate well across different systems. Tbh I'm still pretty new to this, but I've been super cautious about the reliability of these different designs lately. I actually had a bad experience with a different pair where the frame started creaking, and it totally distracted me from the "flat" response I was supposed to be hearing, you know? I ended up going with my current setup—the newer open-back style from them—mostly because the build felt like it could actually survive a real studio environment. If the hardware isn't 100% stable, I feel like I can't trust the spatial imaging anyway. I'm just looking for something that won't break or start rattling mid-session, because that's what makes a decision "reliable" for me. Are the higher-end closed models better for that, tho?

But honestly, I’m gonna have to play devil’s advocate here. While the hype around the newer open-backs is real, from a market analysis perspective, you're often paying a massive premium for 'spatial audio' branding that doesn't necessarily make your standard stereo mixes any better. If budget and translation are your main concerns, the price-to-performance ratio on the latest Sony gear is actually kind of tough to justify compared to other industry standards. Like, for the $400ish you'd spend on the MV1, you could grab the Sennheiser+HD+600+Open+Back+Professional+Headphone&linkCode=osi&tag=5422-20" target="_blank" rel="nofollow sponsored">Sennheiser HD 600 Open Back Professional Headphone which is arguably the global benchmark for a flat, neutral response and has much better long-term parts availability for a working studio. Tbh, if you really want to stay with the Sony ecosystem but hate that 7506 brightness, hunting down a clean used pair of the Sony MDR-V6 Studio Monitor Headphones is a way more cost-effective move. They share the same rugged chassis but have a significantly smoother, flatter curve in the high-mids that won't kill your ears during an 8-hour session. Basically, don't feel like you have to drop half a grand on the newest flagship just to get a reliable mix...
