And you're completely right, as it's been said along several posts, if we just look at electronics:

Double voltage (and double amplitude): +6dB
Double power: +3dB

When converting a signal into SPL by a speaker or HP:
Double pressure (Pascals or DaPa): +6dB

Regarding human hearing... since not all we hear the same, it's needed to look at statistics and the results of tests carried on a population, considering age, health status, etc.

Hearing double louder: +10dB

The lack of lineality is what makes us being more sensitive at 3.5KHz and way more insensitive at low frequencies and higher ones. You need different increases of SPL at different frequencies to have them heard and also to produce the sensation that you're listening louder and of course double louder. That is expressed in the Fletcher-Munson curves, which you can see in the Wiki article on Phon I mentioned in a earlier post.

Regards.

That guy would be me! Supposedly they are the same, but having now had both (I finally got my authentic Triple.Fi's), they sound much better, and even the cord it comes with seems slightly higher quality.

Oh, and I got my Triple.Fi's for roughly $270 at Full Compass (pm me for details), but they were also selling the IE-40's for $360. Same freakin' thing, supposedly, the re-branded one for almost $100 more. Crazy.

I do have an interesting situation, that I'm assuming has to do with how deep the IEM goes in your ear canal. Right now, I'm experiencing a tremendous mid-bass or lower-mid hump, copious amounts of bass, and an extremely rolled off high end. For example, there is no "sparkle" to Sufjan Stevens' songs, and that's one of the production aspects that he's known for.

Any suggestions would be immensely appreciated, as I already love the bass on these puppies.

ive found that sometimes the TF10 bass is a bit too much, might be a result of my tomahawk, but right now really content with them and iPods Bass Reducer EQ, fantasic.

As for the fit, I am uncertein as to how u are managing to lose the highs, maybe the seal is too good ? not sure, have u experimented with different tips?

Due to the wide sound bore, they don't go deep into your ear at all. They just kind of sit there barely sealed in.

Your description sounds about right. What headphone/IEM are you coming from previously? If your bass is big you are getting a good seal. I do not find TFP's bright or sparkly at all. It's dry and airy. They took me about a week to get use to and really appreciate. Coming from ER4's I thought they sounded pretty bad at first.

Practically every headphone I've tried (including the HD650) seems to have more treble than this. The best example I can think of is cymbals. It sounds like the hi-hat's are behind a blanket.

It's probably the recessed mids bothering you a little bit. I'd say be patient for a few days. Hopefully over a few days you will think they are burning in when it will merely be your ears adjusting to the sound sig.

While my ER4P is much more balanced and articulate, TFP's are quite fun and euphoric. Can't say too much bad about them. It is indeed a BIG sound.

This might sound like a n00b question, but would you consider a hi-hat to be mids? I would call that in the high treble arena.

Regardless, I will listen to them a lot more. But if I can't get used to it, would the Ety's have a brighter sound?

I am still waiting for my Etys to come back, but I'd say the Ety's are more brighter as a result of the lack of low end they have. TF10s, I find have the high end detail that the ER4 have, but also pack the bass that set them as a awesome, engaging earphone.

When I get my ER4 back, it will be more for analytical listening, for when I want to sit and pick out bits of music etc, but the TF10s are just really fun, get my feet tapping and so forth.

I still prefer the TF10, in what I like to refer to as ER4 mode, with iPod on bass reducer just allowing me to be fed more highs than lows, despite my love for bass, sometimes I just want the detail, this is only being done until I get the ER4 back!

Yes, I would consider a hi-hat an upper-mid.

I would consider Ety MUCH brighter, too much for many people. It's the best treble. Nothing is even close, actually. Those IEM's that get close tend to be siblant and splashy. But the Etys will be less bass than TFP, no doubt.

Right I would consider the ER4 to be fairly unbalanced. The Triple.fi may be slightly recessed in the mids but the bass to treble is fairly even. The Ety leans a lot towards the treble range because it looks fairly flat on a frequency response graph. IEM's should have a fairly significant roll off in the highs in order to sound neutral because of the proximity of the drivers to your ear drum, as opposed to full circum-aural headphones which should remain pretty flat all the way through. Other than a slight peak in the 2kHz range to compensate for auricular resonance the highs should curve down slowly from about 1kHz to the end of the treble extension to sound truly neutral.

So, last night I decided I'd give the Triple.Fi's another whirl before bed. I just had them plugged into my iPod 5G, unamped. I'm not sure if it was because I was lying down... or the way I was wearing them, but WOW...

the upper mid/treble energy that wasn't there before is now there.

The moral of the story is, these things (for whatever reason) now sound beautiful.

Interesting...If neutral is to be considered rolled off, I guess I don't like it then. To my ears even TFP needs EQ to crispin it up just a tad. Not as severely rolled off as Shures but Ety is the only IEM whose treble sounds "correct" to me. Westone makes hearing aids. Shure makes mics. UE doesn't do anything other than IEMs but only knows what the hearing aid makers know. Etymotic, however, develops the technologies and the internal components and research equipment that the hearing aid makers use to make the hearing aids. Of the bunch, Etymotic is the only one that really truly understands the science of sound and how to input and output it. Hearing aid makers just know how to put the components invented by Etymotic, into earpieces. Having said that we can all have our preferences in sound but to infer that Ety missed the boat in compensating for the driver distance to the ear is completely off base. UE promotes TFP as studio reference grade??? Not even close. They are very colored because most people prefer a colored sound. Ety are not colored, they are indeed THE reference IEM.

Having said that the ER4's and TFP's are still my favorite IEM's but Ilike them for different reasons and wouldn't want to give up either one.
