Which Sony headphones am I actually supposed to get for a reliable studio mix because I am losing my mind over here? I'm currently stuck between the industry standard MDR-7506 and those new open-back MDR-MV1s and I just can't decide which is gonna save my projects.

I'm finishing up an EP for this local band in Seattle and I have to have it done by next Friday but my current setup is lying to me. I'm mixing in a tiny bedroom with zero acoustic treatment so I'm 100% dependent on my headphones right now. My old ones just broke and every time I take a mix to my car it sounds like mud in the low end and way too sharp in the highs. It is so frustrating to spend six hours on a vocal track just to realize it sounds like garbage everywhere else.

My budget is pretty firm at $400 and I need to buy them like today so they arrive in time.

• MDR-7506: Everyone uses them but are they too bright for long sessions?
• MDR-MV1: People say the spatial stuff is great but is the open-back design gonna be a problem for detail?
• MDR-CD900ST: I saw these imports online but idk if they're worth the hassle of shipping from Japan.

I'm leaning towards the MV1s because they look more comfortable for 8 hour days but I'm worried they won't be as honest as the 7506s. Which one is actually gonna give me a mix that translates?
