My cheaper headphones are all failing and I need to grab a few pair of whatever is the best value iem today, similar to how the quarks were when I bought them 3-4 years ago.
Is it still the Quarks? I saw something from 7hz that was really popular at $30 but I think it has a detachable cable. I’ll have those pins snapped off in a week.

+1 to 7hz I always recommend the Crinacle Zero:2 IEMs
That’s the other one that I was considering. I just wish they used a different type of cable connection. The pins scare me but I’ll definitely buy them anyway.
