Buy a couple 300ohms or less trimmer pots and mount them in a mini altoids tin or something :) The caveat is that you'll need a digital multimeter to read the resistance, but that'll take all of 1 minute and you're off to the races.

Would passive volume controler from Shure help with the impedance?

I read somewhere here that somebody suggest to use that.

Anybody tried?

Thanks

Wonder if anybody tried S / P / B versions?
Anybody know the impedance for B versions?
Would add more impedance / 100 ohm resistor add more bass to the B version?

Trying to improve with Apuresound cable to no avail hence the resistor solution :-(

Want to collect them all to get the full Ety experience :-)

Thanks

It's a bit more complicated than that. According to Rin Choi's measurements, the ER4B's impedance is fairly flat until 3 kHz where it decreases. Therefore adding a serial resistor will decrease the treble above 3 kHz, in other words, relatively increase everything below 3 kHz.

The Shure volume controller would be adding a variable resistor in series.

The 4B has a capacitive component that throws off the resistance curve.  That said, it also boosts treble with more impedance.  In fact it is the most treble heavy of the line.  For all that Rin talks about the Ety line, the pages for them are pretty sparse.  Anyway here are the three in line.  Keeping mind the only difference is inline resistance and in the case of the B a cap.

Thanks guys.
Really appreciate your inputs.

I think I give up.
Can't get the better bass with resistor changes / impedance. Already played with some tips but the difference is minor.

Looks like i have to give in and get the ER4-p with an S adapter.

The impedance of an ideal capacitor is purely reactive with no resistive component.

There are people who make P/S/B adapters but they won't be cheap.

 

Alternatively you can use EQ to tweak the bass to whatever you want.

Just curious, what happens if one adds 75 / 100 ohm to ER4-B?

Sibilance? Dryness? Thinness of the bass? Smaller sounstage?

Anybody played with this before?
Thanks

On the other topic, I saw a Klipsch XIi and wonder if they sound similar to ER4?
Anybody ever tried them?

Single BA and construction is kinda cool with grey metal finish.

They are not at all like the er4`s, they have a bassy signature somewhat like the gr07. Notably, there is more roll off in the highs, yet they are smoother, and more emphasis on the bass and mids giving a thicker, more lush sound, soundstage and intrument seperation is about the same and isolation is also great. They are more compact than the er4`s and the cable is much thinner without the large cable divider that houses the resistors.They are a tad less microphonic due to the shorter stem length of the earpieces.

Thanks ryanjsoo,

I try to find some impressions around here but found none

And yet once gone the curves are restored...

That's because impedance is the sum of resistance and reactance.

True.

post #3495 of 4771

i dont imagine the B adaptrers have the built in caps huh? prob just the 100ohm resistors.

 

is there a big difference in sound with the s  and b? as far as sound quality
