hey, i found out one method that can fit in the ears quite easily,

guess what method im using??

just open your mouth as big when you say "AHH", ur ear part there will feel kinda relax and the bud can plug easily,
i think of this method coz some how it hv some similarity of singing technique...

if plug in correctly, the sound can be perfectly listen by ears.

just my experience.

hey, i just found out that my ear are best using the small sleeve.

all these while im using the mid sleeve, which i thought the sound already good, but today i change to the small sleeve, found that some details is clearer. my ear not able to fit the large sleeve.

Guys, you all hv to try which sleeve suit urself to get the best out of ur mylar.

BTW im using x3 only. i found that the bass response is getting better burn-in along with my D1.
