I kinda like the Gray triple flange as they give the most detail and they're not as easy to look messy unlike the white triples which tends to discolor at times.
My ER4SR don't come with grey I think? I have transparent blue / white and some white-ish larger tri flange. The other are foam. Could you please share which one it is?
Also for everyone else, with the deep insertion, you are prone to getting ear wax pushed deeper and thus clogging your ear if you use these daily right? How do you guys deal with it?
