Guys it appears I have mislead you all. Check the edited first post for the details.

edit: WARNING! There is a chance that this could damage your equipment! Apparently Creative messed with the A/V out so that you couldn't use generic 3.5mm->3xRCA AV cables (so they could sell you there own expensive version). As far as I can tell using a regular 3.5mm audio jack might leave you...

Just did a few more quick measurements. The headphone is an Etymotic ER6i, the source is a Creative Zen NX (which has 25 volume levels), and the SPL meter is the analgoue radio shack number. The measurement in dbs is averaged, and I haven't bothered getting an estimate for peak dbs. volume...

I took some unscientific SPL measurements* (using the radio shack spl meter) of my er6is driven by my creative zen. At 5** out of 25 it was averaging 80dbs. I'd be careful listenind to IEMs as loud as some of you are, especially since they are highly efficient and will produce higher SPLs then...

Interesting, but how do you know if you need it done? I'm mid 20s, never really used q-tips, never had problems with ear wax coming out of my ears, and no feeling that sounds are muffled. The only thing that springs to mind is that I listen to music a bit louder then other people, but it's...

When I first tried it I was wearing some IEMs, and all I got was the volume increasing in one channel and decreasing in the other backwards and forwards, but without any spatial content (although it of course worked really well with full sized cans). I guess you need the sound to hit your ears...

Hmmm, interesting. As it happens I have an ear mould here that I could create a negative of for use in a DIY IEM. I have a question though, do the drivers need to be open to the air, or could they be directly encased in say a resin to? If they could then it would be relatively straight...

I don't mean to be a wet blanket, but a picture (or graph) really is worth a thousand words in this case. Have a look at Comfy's graph- that puppy shows an exponential growth that would be almost impossible to appreciate if he just listed the model numbers or even how much he had spent. Oh...

I honestly have no clue, so why do you need an in-line amplifier (isn't that what the headphone amp is for)? And you wouldn't need a corssover if you went with a single driver right?

On reflection, if I already owned a suitable sacrificial headphone I would, but it could turn out to be a bit pricey.

Mine seem to be pretty air tight as it is, but it's definetly worth a shot. Thanks for the tip mate.

Hi all, pretty self explanatory. I'm curious to see what the trend is, although I already have my suspicions...
