I got some IE8s. They showed promise, but no good seal. I want a good seal for isolation. I know what half of you will say about them and not expecting isolation, and I dont care. I know how to use an EQ
Anywho, what I did what this:
Got some foam earplugs. The kind used in industry, and readily available in bulk for very cheap (think shure foam inserts but about twice as long).
Pick out some sennheisser inserts that youre NEVER going to use.
Cut the core out of them. You want to keep it as cylindrical as possible.
Cut one of the earplugs in half.
Compress them HARD lengthways into a disk. They will not totally recover from this, and thats actually a good thing.
Use a hole punch of suitable diameter or carefully use a pair of scissors while the half-plugs are compressed/maintaining their compression and cut a hole in the centre to fit the core of the senn insert. (Obviously make it a tiny bit too small for some friction)
Put the cores in the plugs.
Wait for the plugs to expand. This will take a lot longer than usual because you compressed them so hard to be able to cut them accurately. If you got the same (pretty much ubiquitous) plugs I did the half-plugs will relax to almost the same length/thickness/whatever as the cores (a little more, which is what you want, obviously).
When done, use a pin to put tiny amounts of superglue (coat the pin and stick it in there and move it about a bit) in the interface between the core and the plug.
Trim the edges of the plug that will be going in your ears, so they dont flare out in your ears and attenuate high end.
You can repeat the compress & cut process with a new set of plugs if the first are too wide, and make another set, or cut strips off the edge of another set and glue them to the first to widen them out.
I've done this and got much better seal, great isolation (shure foamies level) and the sound is fuller, and deeper, but not boomier. I didnt find them veiled at all to begin with, and this process has only served to sweeten the top end somewhat, but not diminish or muddy it at all
The plugs, as they dont go in your canal, take the shape of your ear quickly and I dont find they need compression every time you put them in - you just put them in (this, I suspect, is subject to how good a fit they are for you, but as outlined that can be adjusted).
P.S. This is off a cowon iaudio7, settings:
EQ: 80Hz up two notches, 220 down 2 notches, all others unadjusted.
Band widths and centre pitches unaltered (well done for thinking them out well to begin with, cowon people).
BBE: 2
Mach bass: 2
MP enhance on
IE8 Bass dial on zero. I found it added a lot of low mid bloat with the actual low end. I believe the low mids, not the bass, is what is responsible for many people believing these phones to be "veiled". Subtly and intelligently EQ'd they are not.
Another reason would be the proliferation of ipods round here. Top end IEMs and an mp3 player with some of the worst DACs out there? Really? But anyway, I may or may not piss into that wind another time
Anyway, I hope someone out there found this usefull. Its very possible to get the IE8s to isolate well, play to their strengths of powerfull low end and warm, unfatigueing sound AND have them be accurate and clear. And you dont have to throw money at it to do it
