Unfortunately, my current headphones is the last pair and they are probably going to die randomly any day. I have literally no idea how "in the know" people find good headphones these days, especially if you don't want earmuff headphones or apple earpod knock-offs. It looks like all companies are only making one of those instead of normal ones.
The amazon listing was 1984'd so you can only find it on ??? websites.
Note: this is mostly just a rant.
Yeah you can get solid earphones for $20. $100 headphones (from good brands) sound noticeably better than $20 headphones but if you spend anymore than that then you're paying for some audiophile woo or "capitalist innovation" features like the inability to work without an app or being dependent on a non-replaceable battery.
