If you still love Etymotic ER4, this is the thread for you... - Page 261

I'm currently rocking the huge yellow ety foams! They look absurd, are a real pain to insert properly and get dirty very quickly but the isolation and sound/detail levels are insane!

So if i use the lead it's exactly the same as having a er4s?

Yes, if you use the supplied resistor adapter, it'll turn your ER4PT into an ER4S and without the adapter it becomes the ER4P. In other words ER4PT is like an IEM Transformer biggrin.gif

Guys, I think this might be a bit off topic but I would still like to ask this question about the 75 ohms S adapter by etymotic. Is it just plainly a 3.5 mm male jack to a simple resistor then to a female 3.5mm? Or is there anything else. If I were to diy a resistor on my own with nothing inbetween and proper shielding to prevent EMI. Would that colour the sound in anyway? Just plain resistors.

OK just wanted to make sure I understood correctly. I take it that there is still a lot of cable noise if you walk around with them?

Yes the microphonics' (cable noise) still there. Every bit of it redface.gif

Run the cable over your ear and it eliminates the microphonics.

Yes I've tried wearing it over the ear, it definitely minimized the microphonics but not completely. You definitely can hear the microphonics if you're walking around, but not as bad as if you're wearing it down

You need a resistor on each channel and that's it. You should have the same quality as the ety adapter. It's just two small resistors.

However, resistor tolerance might matter, although it shouldn't be a big difference. I think someone said 1% is good tolerance. Maybe someone can verify this. Also, how do you determine what power resistor? 1 watt 75 ohm 1% tolerance??

Just be sure the resistors you used is metal film. Other kind of resistor is usually worst for SQ. Good tolerance is optional as long as you can match them with multimeter.

what about wattage?

We are mostly dealing with a few hundred of mW in the headphone world at most (excluding those headphone that need power amp to drive) so 1W should be way more than needed. If size is a concern, there are SMD type metal film resistor you can use, slightly more expensive but still much cheaper than caps.

I was actually thinking a quarter watt would be more than enough.

That's what I was thinking.  Just basing the values off of my jds c5, the max output with a worst case headphone is about 80 milliwatts, which would be .08 watts, which would be about 1/12 of a watt.  If I did the math right a quarter watt is plenty... no?
