Judging from your measurements, which tips do you believe is the best for this IEM? Sorry, I am bad at interpreting graphs. Thanks in advance!
As long as you avoid sleeves with the stem(bore) size longer/thinner than that of the stock sleeves, it should be OK.
I know this is old, but do you remember what meelec eartips you used (m6, m-duo, m9, etc)? Thanks a bunch.
