I own a Simgot EW 300 and Kfine Delci. I never faced any issues with the nozzle. You could maybe try changing the eartip material as well. May be try silicon eartip like Spinfit or try some foam eartips. Spinfit is a bit on the expensive though.

Moondrop Chu 2 is on the lower budget side, so I’m guessing it could be due to cost cutting from Moondrop. The price of IEMs increased nearly 30% in the past 1 year, so the cost cutting thing could be a possibility.

Typical of Activision to fuck up the same game they have been making for the past 10 years
