Impedance

[Slivester 0]

Is there a way to increase the impedance via an add-on to IEM's plug?

How about a short length of cable? Easier and can keep yr iems stock.

if increase impedence, will the bass increases or clarity?

[norseman 0]

I would think clarity and treble at the expense of some bass.

The ER4P->S cable or something similar should serve the purpose.

IME, increasing the in-line impedance (not driver impedance, I don't think anyone can do that easily) for armature driver IEMs reduce the overall amount of general bass and brings the treble regions into a more forward presentation, but it cuts the treble in dynamic driver based eargear and may or may not murkify the bass regions in general.

 

For the armature driver based IEMs tried on my 200 Ohm resistor, I've tried the Aurvana, E4, UM1, ER6i and CK9. The Aurvana benefits very heavily from this, it'll sound like a different beast altogether IMO.

Yeah, I just took over a terribly under utilised Aurvana from a friend (without charge actually hehe), and I am generally very unsatisfied with its treble and mids.

 

This resistor, how does it look like?

My resistor is just a Shure PA235 volume control unit.

 

At 0 volume cut, its at 0 Hms resistance, and at max, its a 556 Ohm resistor. I measured the L/R channels using a multimeter and brought the value to ~203 Ohms. Aron helped me shield the volume slider using a heatshrink tube
