Best eartips for Simgot EA1000

Just got my Simgot EA1000. Wow great IEM with nice open sound.

Struggling a bit with the eartips. Tried several, but none is really great.

Stock tips: these are OK
Moondrop Springtips: seal is not great.
TRI Clarion: sound great, but not very comfortable
Dunu S+S: small is very comfortable, but seal is not good (hollow sound). Medium seal and sound is good, but not comfortable. Hurts my ears after some time.
