Hi all, been lurking for a while, but I'm close to saving up enough money to step up to $300 tier headphones. I was wondering if anyone had experience with the ZMF Classics with regards to metal. I also have thought about the Meze 99 Classics, but I would prefer semi-open headphones. Open to other recommendations as well. I value detail, comfort, soundstage depth, and bass in that order. I have a 1st gen Schiit Magni/Modi stack and lossless/Spotify Premium high quality source.
The Meze 99 Classics are very good, but very weird headphones. Their sound signature lends itself well to most genres of metal. For $309, they're very good. They have nice, punchy bass, a wonderful midrange, and a very good - but not top-notch treble region.
Regarding comfort, make sure you get the ones with the larger ear pads. I had the ones with the smaller ones, and they weren't comfortable for me, especially when I wore my glasses.
So on to portability. They are very portable in some respects, but not others. They are very lightweight and easy to drive. However, they have a really wide headband and they're not foldable.
This may sound negative, but overall, I liked them, I just couldn't love them because of the fit issues.
For $300, they're really good, but I prefer the Audeze Sine and - surprisingly - the RBH HP-2 for portable use.
Ultimately, they're really good for metal, if you don't mind slightly boosted bass, don't mind the fit, and
love the styling.
If possible, try to listen to them first to find out if you find them comfortable.
Let me know if you want to know anything more specific. I only had them a few weeks due to the fit issues, but I thought they were really good for the price.
Good luck either way!
