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.

Are Zero Audio still around? I picked up a pair of their Carbo Mezzo wired earbuds some years ago in Japan and was very happy with the sound quality.
It doesn’t appear that they are, unless you’re referring to 7hz who make both Crinacle Zero and Salnotes Zero
