Those are Spinfit CP100. I've tried Acoustune 07, Final and Spiral dots. Spiral dots gave the best sound performance but the nozzles of the MH755 are just too short to get a secure fit with Spiral dots. Final was a no, they amplified the bass response to the point it masked everything else. Acoustune on the other hand helped the treble out a little bit which was fine by me but then I just couldn't get a good fit with them on my left ear.What tips are you using? Thanks
So, at the end of the day I'm just settled with the CP100.
