My first customs made me nauseaus for about ten minutes secondary to inner ear pressure changes. no problems since. They were also my first multi-driver balanced armatures so that was quite different as well.

UGH! Tomorrow's flight is gonna be the longest flight ever.
let us know if you find them better than the denon modded 2000 that you sold it for. especially in the area of bass impact and punch for rock (reproduce kick drums).

Will do. I really enjoyed my Denons, especially with the WA6. Bass was tight and visceral, and kick drums were very engaging.

I'm not a basshead by any means, but impact and especially texture are particularly important to me.

OK, here's a common mistake for wearing customs.







As you can see, not tucking that top part into inside fold of the concha of the outer ear will not allow the Custom ear piece to seat fully, and the ear piece is then at an angle and not straight in.

Ed if you look at my picture in my gallery did they look fully seated?

Nice work Ed!

It makes sense that first-time customs users, not unlike buyers of universal IEM's, would have to learn how to get the proper seating and seal of their monitor.

Makes me wonder if Jamato's experience this afternoon was a product of having to fiddle a bit with getting the right fit. It seems as though it's possible with customs to actually get a seal, which would signal that they're properly fitted, when in fact the IEM is still not in the ideal position. Is this correct?

or he could have a bad fit and need a refit XD um it is all based of seal mainly if you have a proper seal you should be fine.

It becomes second nature after a while. UE put out a nice video about the insert and roll forward trick. The popping them back out trick I got here at Head-fi.

I think it was just that they needed some play time. They are seated in my ears the same as this afternoon and realizing how they needed to be seated before I got them helped.

They sure do take you into the music. This afternoon my left driver started to rattle with any heavy bass after some had played for the first time. I figured, on no here we go, a driver that has developed a vibration but then it went away.

I notice that some of my Grateful Dead recordings that sounded ok sound more enjoyable because some of the spatial sounds could not be heard. The hall sounds are more easily heard and incorporated into the recording adding to the realism and connection with the moment.

They do make it easy to know which amps have hiss with IEM's and which ones don't.

Looks fully seated to me.

That's what I'd figured, that as long as you've got a seal, then fit is no longer an issue, but I wasn't sure whether it was possible to both get a seal and still not have achieved proper fit.

One of the ways that I've heard people describe the advantage of customs over universals is that the canal portion of the custom being in contact with the ear canal itself creates additional sound conduction (or something to that effect).

When I try to visualize it, I can imagine the canal portion of the custom being sufficiently seated to create a seal, while the housing part could potentially be angled differently, as in Edwood's diagram.

If seal was all that was really important with a custom, and powderhound in the ES3X thread stated that the individual sound tubes present in customs DOES NOT have a significant effect on sound in comparison to universals, then it begs the question as to what actually creates the better sound presentation in customs compared to universals.

It seems like it has to be some combination of driver placement as well as the effect of the canal portion of the custom being in physical contact with the length of the ear canal, but again, I'm trying to use logic and inference, which is probably not the best way to determine these things...

Ok great yeah I hold my ear up and open my mouth and get a pretty kick ass seal now. Interesting seems John is really warming up to the jh-13's now. Now I don't want to go into the craziness of burn in buy cable burn in? Hmmm would be interested to hear someone chime in on that lol.

Distance of the drivers themselves to the inner ear, along with angle of the sound tubes are what primarily make the difference.

One of the things I think IEM's do that can't be matched by full-sized headphones, unless maybe we're talking about stats, which I've never used, is the speed of the balanced armatures combined with the closed nature of an IEM.

This can reveal spatial effects that are difficult to capture with open headphones because of their airiness, while being hard to capture with closed headphones because of their relative lack of speed.

Maybe I'm wrong on that because I have a hard time trying to describe that quality you're describing, but think I've observed something similar.
