Probably yes, but I usually like to keep it a little high since there is no harm in doing so. Higher rated resistor tends to generate less heat, which might result in less theme noise. Of course I never measure them myself but at least that's the theory.

 

 

It should do. There are argument on which brand / type of  resistor sounds best but I usually like to keep it simple and opt for Vishay personally as much as I can, since it has been widely used for this kind of application.

My thoughts exactly on the heat and brand...

Well I've all but given up on over the ear wear for various reasons. Wore them down tonight with the shirt clip- seems fairly acceptable. I'll have to wear them out and about like this and see how well it holds microphonics at bay. At least the comply P's have resolved the comfort issues.

Luisdent has shared some good EQ options, so I thought I'd share mine (with red filters) and it's actually not too far from his.
30hz, Q=.5, +5db
2.4k, Q=2.5, -2db
7250hz, Q=5, +1db

This feels more neutral to my ears but even without eq, I can really enjoy them.

Out of curiosity did you ever try this? It's completely solved my over the ear issues. Comfort is great.



Also interesting you brought down the mids even with the reds. That would probably put your reds eq around 2k to be about 2db less than luisdent's eq on the greens. Personally I find the mids on the reds to be perfect. But lately luisdent's eq on the greens has really been doing it for me. So damn clear. I think an iem with this sound out of the box would change everything.

@luisdent Go with these. You'll have a much easier time implementing them into a cable/plug :) It also has a nice low temp. coefficient, so it'll stay at it's rated value when it heats up. Thin film resistors tend to be best for precision too. You could get a smaller package code, but it'll get tougher to solder if you don't have the proper equipment.

Here is an article that might interest anyone who are looking for resistor's SQ:

Seems like bulk foil wins the day.

 

p/s: really expensive stuff too.

Excellent info. I wonder how audible the differences are with only the two inline resistors, as opposed to having many in an amp design. Is that why the ety adapter is $50? $25 per resistor? :-P

I think I read it somewhere Ety use your typical metal film on their adapter. Material cost isn't equal to price tag in the headphone world, or else 95% of all headphones shouldn't cost more than $100. It is usually the hidden cost of running a business that makes thing much more expensive.

Repair broken er4p pin connector smily_headphones1.gif

That looks pretty cool. What connectors are those?

Yeah you can tell by looking at the resistors inside the pod that they are metal films. Most modern-day amps use metal films. Only in some cases will you see carbon and oxides, primarily in tube amps.

I haven't used my ER4p phones for a couple of years.  They were purchased around 2002, and generally used with a Xin SuperMacro IV amp.

In the past few years, I've been using some other IEMs and headphones, but I do miss the ETY sound.

I'm resurrecting that system, but found that the (original non-twisted) cables were split/cracked. 

I sent them back to Etymotic for a cable repair, and they just informed me that the unit should be replaced instead of repaired because there was also a problem with the transducers. 

So, for $130 they should be sending a replacement unit soon. 

I am looking forward to having the music back in my head.

Pretty good deal. Out of warranty. So you're basically getting a new set at least 50% off. :-)
post #3930 of 4970

A fair deal.  Likely no accessories, and definitely no warranty (I asked about it).  I'll report back about whatever arrives.
