I have 10+ iems and although I have a current favorite I enjoy trying new/different sets. Sometimes I'll grab a certain set when I feel like listening to specific music. This is most likely due to the wide variety of music I enjoy. I doubt I'll ever buy a set and decide not to ever purchase another. As long as you're not using your mortgage/car payment..... enjoy the ride!

I am currently enjoying the ikko oh10 but continue to pick up the truthear X Crinacle Zero depending on what I'm listening to.

That's so funny man, I'm in the exact same spot. I finally figured out that I'm not in my car enough anymore to warrant spending money on a system I never listen to. I started with the Aria's and continued down the rabbit hole. I was just showing my wife different watch cases the other night.
