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.

It doesn’t appear that they are, unless you’re referring to 7hz who make both Crinacle Zero and Salnotes Zero
