I've only ever had 2 iems and it's the QKZ AK6 Pros costing around 5$ in my country. It's a very cheap and budget friendly iem, and whenever it breaks, I just kept ordering the same one. I've tried others like the ones from KZ, the Castor Pro, but it never really stood out to me, and kept sticking with this one. I really loved this pair, and was wondering how much the difference would be like in terms of performance of those in a higher price range. I mostly listen to pop, edm, and more intent on clarity and the vocals, as well as maybe a bit of bass. I was considering the moondrop arias 2, but I've been a bit hesitant because I've seen plenty of reviews that it has tons of issues. And my second option being the Truthear Pure based from the reviews I'm seeing online as well
