A note about the CP155 tips. Just tried them out this morning on the Variations.
I tried them on another IEM last night with poor results and wasn’t impressed because they are so long, they were touching my brain! 
I have them in my ears with the Variations right now. These tips appear to be made for the Moondrop hybrid shell design. The tips slide on the nozzles perfectly and I’m experiencing end-game level comfort and everything sounds amazing. I think I enjoy the Variations even more now than I did with CP145! WOW!
Agreed, I wouldn’t choose to listen to the Variations with genres like metal or classic rock. That would make no sense. Rap, pop, electronic, dance, Variations is king. Anything sub bass focused or with female vocals.
