Difference between etymotic er4p and er4s?

Cool - I believe I'm better off just getting a cheap adaptor off of eBay vs the one sold by etymotic, yes?

Well, I bought what was supposed to be a genuine "Ety" adapter off of eBay and yes - seems to do the trick.  AFAIK, it appears to be genuine.


That said, I really don't notice any difference in frequency response.  It's more of a gain convenience.  Tricking the ER-4 into an "S" means that you can use an amp with reasonable power and still be able to adjust the volume with some bit of flexibility.  Put an ER-4P directly into that situation and you're down on the first quarter of the volume dial or less, nothing more.
