Headphoneus Supremus
IIRC, Penon Audio should have those.
Someone showed me this link on Penon, "https://penonaudio.com/3.5mm-impedance-adapter.html".
Is this something like what others are using?
Are there any better quality options out there?
And is it true the ER3XR with a 20 or 23 OHM resistor inline makes its sound signature very close to the ER4?
It appears the 20 ohm resistor has a range of 20-30 ohm. No idea if that is an issue or not?

Impedance adapter is used for noise reduction to reduce background noise , protect hearing ,it suit for high sensitivity low impedance headphones .
[*]Make the sound more pure .
[*]Whether you use any headphones, any player, any amp, noise all filtered
[*]Connector : 3.5mm Male to 3.5mm Female
[*]Black pins:20 ohm (20-30 ohm) Because the impedance range is too small, it is hard to make sure it is 100% 20 ohm[/QUOTE]
