Didn't realize those were called "A8".
The page I ordered from called them "Disassembled pk1 shell".

Has anyone any experience of using A8 unit drivers?
They cost around £8 each - I plan eventually to use them in a DIY build......after initially practicing with much cheaper drivers via Taobao.

I made a couple of pairs with the Fever A8 16 ohm Sunrise SR2 drivers, I actually put them in an MX500 shell and they sound terrific

Yes those are the ones

Completely depends of the (tuning in) the yuin shells, so hard to describe, but globally you probably have one of the best 14.8mm drivers with those, and you can have much fun to tweak with in-shells tuning

Can we put these 14.8mm red film drivers in **** pt 25 shell?

If PT25 supports 14.8mm drivers then yes, no idea otherwise

They use a 47ohm smd resistor (marked 470) in series in each driver.

I noticed that, that is why I'm interested, I modded the HiFiMan HE350 by adding a resistor and a few other components in each cup to tame the shrill highs once

Damn, those original PK1 red film drivers are sounding SO good! they are very easy to tune thanks to some mods in the shell.
I perfectly modded mine for electronic musics, they have the best V sounding that I've ever heard from any PK shell. Equiped with full thick foams, they have unbelievable subbass and bass impact, good mids, and exceptionally detailed highs, with overall natural and good transparency.
My yet best PK mod so far. I will make some pictures soon

Please stay us tuned for your impressions on those drivers, looks promising

Here are my 2 new beasts (my yet best creations and references)

Featuring :

• 150 ohm drivers in Yuin shells modded (extremely deep sub-bass and impact in bass for a yuin shell, with very good mids and very good highs/details)
• 150 ohm drivers in MX500 shells modded (my reference, very good sub/bass, deep and spacious soundstage, very natural and transparent sounding, excellent mids and best highs/details)

Cheers'

What cable did you use?

What cable did you use?

copper

Made a couple of earbuds today:

in the rear 35 ohm PET drivers with copper cable

in the forefront clear shells, blue/silver braided cable and 30 ohm old reclaimed drivers I was lucky to receive.

Hi guys,
I want to buy a new soldering station for earbud repair or DIY. I have never done soldering myself before, should I go with micro soldering station or mini.
What voltage is required and what kind of iron do you guys use.
I know these questions are very basic not sure even I should ask in this thread, I would appreciate any kind of recommendations/suggestions
