HOLY S*** BATMAN!!! most of my iems are using spiral dots since Ive been A-Bing tips to many iems and in the end always settled down with JVC spiral dots which give clear mids and clean bass, and smoothing harsh mostly. Never looked back. My Kanas Pro is at around 60 hours now sound signature have been changed from :
0 hours very flat with additional feel like separate stand alone sub bass,
20 hours starts to open every range,
30-40 hours very clear mids, open highs and air, and "building bridge" from mid bass to sub bass (in a good way)
60 hours sub bass has reduced a bit, high mids more forward
all using spiral dots from the starts. I will wait until 100 hours to enjoy it, but my curiousity really cant wait and sometimes listening to my half baked KP, with spiral dots, i got good fit, but too much high mids sometimes if listening in high volume, because of the wide bore, same like original tips i think. i was EQ ing them, bring down a bit high mids and low highs, and add sub bass- mid bass area to my preference. sounds GOOD. but then i just read your post, and tried it, its free anyway and i got so many tips laying around. AND YOU'RE RIGHT BUDDY, using smaller bore made bass more presence, clear and good texture, not bloating bass, and the best of all, I reset all EQ to flat, everything sounddddssss perfect, decent great bass, not over high mids and low highs, everything just balance in a very right amount. Still i adding bass just 2db up, very little bit for more fun, and 1db on mids area, and 16khz for more air. I will give my detail impression later at 100 hours or more.
Oh im using sony tips in the end btw, the one that came with original MH 750 / MH 755, fits are best. Cant thank you enough because you made my day, how to double like that post?
I believe its very good, balanced with a very great bass as a fun factor.
i believe its a clean bass attack that fast and good and well textured. I think i will like it much, but too bad out of my reach right now.
