Finding driver for mdr e282 diy build

Recently i got my hand on a kit of diy mdr e282 shell from china wizard,does you guy have any suggesttion for a cheap earbud with great driver,i see a few option ranging from a25 to a34/44 but i don't know what their equivalent driver is but as it already known that w20/a20 use same driver as e262 but they have gone up in price recently.

 

I was looking at the taoboo and the shells are very expensive. Around $200USD? (it shows 700rmb but when I click on it, it shows 1300rmb)
Someone on headfi DIY it.

My my experience, drivers from MDR-A series has too much bass after transfer it to earbuds shell.

 

I was planning either to source out the best driver variants of e472 ,or get the upgraded e464 driver(from e454) or getting e245(the cheapest ones with driver from e262) or source out driver from e557 or e552(since i heard that one in two of them from some forum i don't remember is on par with e472 as i have both frequency graph of e472 and e557)

 

The 1300rmb is for fully assembled brass copper shell ones with aiwa driver while 700-900mb is only for the shell as i search on xianyu there is three type of shell are being sold, with brass copper or nornal copper for 780 rmb,and the 925 silver ones sold for 980.
