Re: ER4S ear plugs
My experience with the rubber vs foam plugs on the Etys has been just the opposite. As long as I insert the rubber tips in properly and get a good seal, the sound is unmatched by anything I have heard from a decent source. With the foam tips, no matter how I insert them, the sound seems "vailed" to me, especially noticable in the highs. The extended and transparent highs I get with the rubber tips, sound like someone put a curtain up over them. I have learned that with the Etys, everything is in the seal and this depends totally on the shape of your ear canal. You seem to get the best fit with the foam tips, so it is great Etymotic gives you the option. In my case, if the rubber tips were not available, and I had to use the foam tips, I would have returned the etys almost immediately.
I have also found that the Etys are also very sensitive to what source you are using. My Etys sound great with my RioVolt and Total airhead, but sound somewhat thin from my Archos jukebox and Total Airhead combination...

I've just invested in a pair of ER4S ear (canal?) phones, and have been playing around with the two types of ear plugs supplied. Performance is supposed to be identical with both types. The default ones are the white silicone plugs, and I get the impression that moldable plugs are included as an alternative for if the silicones aren't comfortable. In fact with most reviews I've seen, the reviewer hasn't even bothered to try the moldable alternatives.
However... having found the silicones uncomfortable, I thought I'd give the moldables a try. For me the comfort level was an immediate improvement. However I was also suprised to find that the sound isolation was qualitatively better, and more importantly the sound quality improved considerably. The sound stage opened up, there was greater clarity, lower frequencies were clearer with bass notes having better definition, and the phones seemed to go louder with the same source (using a direct feed from a portable CD player).
The question is, has anyone else noticed this difference, or is it a quirk of my ears? On an associated front, has anyone had experience of the Ety's with custom moulded earpieces? I can think of a number of possible differences in the earpieces that may be significant (there is a shorter path between the transducer outlet and the end of the ear plug with the mouldables; the channel into the ear also has a larger bore. The silicones feel as if they pressurize the air within the ear cavity when inserted. This doesn't occur with the moldables). Opinions?
