Hey, thanks for taking the time to read this! I just received my Rose Mini3Pro and they don't have any mesh to stop unwanted debris from entering into the IEM. Is this normal? (first time I've seen it) Any advice or tricks to not accidentally get something in there. I'm open to modding if...

I saw many reviews of the Rose mini2 IEM which looks interesting mainly for the small and comfortable size (I have small ears) and for the balanced sound for the price. I am wondering how are in comparison the theoretically more refined mini4 and mini6 models as I was not able to see any review...
