okay im having some issues about getting a good seal or not, if I plug my e2s in my ear, without music playing, I can easily hear my finger snaps, but when my music is on I can't hear anything unless I try and forcefully make a loud sound, so how do I know I have a good seal?

From my experience, I know I have a good seal when...

1) I have that strange feeling in my ear, a certain 'fullness'
2) If I tap the top of my earlobe, or the the side of my head, I can gear it amplified, compared to if I do it without phones in
3) If I rub my thumb and fingers against each other, I can't hear it.

After a while, you just know you have a good seal, you get used to the feeling

I was at Sensaphonics last week where they told that the test was clearly hearing a 50hz tone. When a seal is achieved, the tone is clearly audible.

place your left and right hand over each respective ear and while applying mild pressure listen for a sound change

if the sound is consistant you have a good seal

or you could stick your head in a five gallon bucket of water and if your inner ear remains dry you [size=medium]know[/size] the seal is good !



just kiddin' about opion #2

OK. They had a test disc that had a 50hz tone on it. Ian (I think) simply had me insert my phones and listen. He said that if tone was clearly audible, a seal was achieved. Without the seal, and with canalphones, the 50hz tone would be inaudible.

So, I came home a did the same test with my trusted Ety 4Ps(Sensaphonics moulds) and the Soft 2xs, this time using a Stereophile Test Disc 2. In the case of the Etys, I could trace clear fundamental tone commencing at 25hz; the Sensas at 20hz but with clearly greater amplitude.

One thing that I haven't tried is to attempt to hear a 50hz tone with a poor seal. I may do this.

I know, that the seal is good, when I'm hesitant to pull the phones out because of the under-inflation the seal creates. An abrupt pull would just hurt too much. So I have to do the "full procedure": pull at my ears and take out the phones with a twisting move...

Joelk, maybe a dumb question, but do you mean listening to a 50Hz tone WITH the phones or listening to a 50Hz tone from a loudspeaker with the plugs on your ears ?
I suppose it is the first, but I would like to be sure.

With the canalphones,of course. Any loudspeakers should be off.
