Quote: ha, thank you for your kind answer~ i'd give up that thought.   haha, neither my IEM nor my ears are dirty, just consider this as something cool.....well, now i know it's not practical...

I am worrying that my IEM(hybrid quad-driver  IEM) might die after cleaning..... anybody did this before? thank you for advicsing~~

all know what is the best girl, this is to try what is a girl first.

Quote: sure thing! that's why i m searching for algorithms to see how components would affect the frequency curve(at the mean time i've found out some frequency curves of some drivers, though). Coz those measuring equipments are too expensive for me to afford. anyway, this is only defined...

finally it's done!

Quote: u mean the flange or the drawing? no drawing, lol, coz it's single driver. for the flange, i think it originally comes with triple silicon flanges, isn't it?

Quote: hi Jim, i see u r everywhere! u r doing a good job, not me, haha. was supposed to deassemble the case of IE1 to make it smaller, but for remaining the original scoustic quality, i kept it that way, ugly, but i still like it....     haha, only counted by materials piling up...

ie1 was too big, i just had it half-buried in the UV GEL     this is toooooooooooooooooooooooooooooo ugly, but it's not a bad virgin trial. for base, it terminates 90% of multible driver IEMs(nobody would doubt that IE1 driver has a brilliant bass, right?). Medium is very good too. the...

BTW, the filter could be cut into 2 pieces. this is the wearing pic  

Drivers: Bass: Bose IE1 Medium: MA850 Treble: knowles ****   Frequency filter: see picture (red to treble driver, blue to bass) parallel linking to MA850 driver ( with its own frequency filter already)   other raw material: UV GEL UV light cable acoustic pipes( silicon...

nope~ haha

this is for you to guess~

not sure...coz i only bought those cheap OEM flanges, all without any brand...(less than 10 cents each, but bought in a batch of 80 pcs....LOL  i guess u'd hv 2 measure the diameter of it although I think most of the shure stuffs will match

Quote: glad u like it~ lol, btw, i got a suggestion for its better performing: change to a triple silicon sheath, as the saying goes, enjoy better if u r ****** deeper....:D  i feel like a 200% raised in its acoustic quality

thx for the above thread~ i've got a lot of diagrams~~hmmm, looking for more exchange apple MA850, dural BA driver
