I'll assume there's a reason you want closed headphones. Typically I've found that for music, open or slightly open can have greater dynamics, but that's a pretty broad brush. I've used closed for decades, but not strictly music.
Drop has the Meze 99 Noir for $200 even. If these really are the Classic with less bling (and less sexy wood finish), then that's a pretty good deal. I was pretty impressed with the Classic back when I heard them, but it's been too long now to remember specifics. I think there's a few zillion reviews of these on YT. I think the Classic started out around $400, and is still $300 at many resellers.
Also worth checking is the
$150 Audio-Technica ATH-M50x, which is a new build of a classic. These used to be really well regarded, no doubt there's plenty of reviews on YT. Tank like build and fold up nice. The M40x is similar, and $50 less, but much leaner as you'd expect.
One I can also give a thumbs-up to is the
Fostex T40RP mk3 series. They come in open, semi-open and closed. I've heard the open only, and thought they were extremely articulate for the price. Can't vouch for the closed, but assume they're voiced as closely as possible. Fostex and I go way back.
One more is the
$150 AKG K371. All of my editing work is on AKG, I love the things. This set is a totally different design than what I'm used to from AKG, a departure from their sort of floating headband. So I can't vouch for comfort. If you're ok with semi-open (as I said, I use them for video/audio editing and don't find outside interference an issue) then these are excellent - the
$150 AKG K240 mk2.
Finally, good old Sennheiser does make some closed models. IMHO, their 6xx is a classic and tough to beat for 4X the price. I have no idea how their closed models sound, but again, probably lots of reviews on YT.
$150 Sennheiser HD25.
