Sony IER-Z1R easily the best bass-head IEMs IMHO

I have Moondrop Arias and Sony IER-Z1Rs. The Sonys cost about 20 times as much, and (in my highly-subjective analysis) sound about 4 times better. I use the Arias more because I can take them out, and I use the Z1Rs for listening at home. You can get amazing IEMs for less than $200, but there’s always going to be better options for more money. If they make you happy, then you’re happy, and you should enjoy that and not go looking for upgrades eternally
