The IT01 are my first IEM (as in EVER) aside from the crap earphones that came with my smartphones (that I literally never used!) and I'm having a hard time with all the supplied tips..
Zeldas review here
https://www.head-fi.org/showcase/ibasso-it01.22774/reviews only increased my confusion, I'm afraid.
- Why are there black tips and semi-translucent ones that are supposedly identical? Are the black ones made of rubber instead of silicone? Ist it just about style?
- What's the difference from the "wide-bored" ones to the narrower ones?
The only difference I can make out is the fact that there seems to be more deep bass with the large tips vs the smaller tips.
I guess, my hearing is so bad that I can safely stop bothering with high-res DAPs and just get a Cowon Plenue D now and enjoy the long battery life
(And there's people who seem to hear difference in different cables
)
What I can say after maybe 10 hours (over several days!) of listening to these IEMS is the following:
The earphones fit my ears (outer ear) perfectly and don't hurt at all. Extremely comfortable.
None of the eartips - be it wide-bore or narrow-bore, Large, Medium or Small - hurt my ears when I wear them (haven't tested the foam tips since I need the IEMs for travel and the tips to last a long time).
The cable is amazing.. With my Sennheiser HD25-1/II I always had issues with the cable generating noise when it scratched on my jacket zipper.
