i’d be open to that, any suggestions?

Recently I bought the 64 audio U4s from headphones.com open box which was $200 cheaper than if I bought it new, and wow, these things blew me away. I have never heard such a detailed sound out of an iem. Previously, I only had the Crinacle Zeros OG, and the SA6 Ultras, but these were on a completely different level from both of them. I’m even thinking of selling my HD600s because the soundstage on these are just as good, and maybe even better. Coming from a mostly over-the-ear headphones person, I am very impressed.
