The left channel of my EPH-100 is now a lot softer then the right
It's aluminum. It's still fairly strong while keeping the weight down. It's also more expensive then stainless steel.
It's aluminum??? What. Everything I read said they were stainless steel.
Guess I should have read from the one site that would be sure to have the correct information: yamaha.com
hmm... a little disappointed to learn they're aluminum.

No, it's brass!
According the Product Bulletin:
"The body is made of high quality brass, similar to that used in trumpets, with helps to minimise sound loss."

Titanium is not an option, too expensive given the quantity needed for these IEMs.
They seem a bit light to be brass (denser than aluminium), and the PDF looks like it was created before the actual launch, it doesn't show the final product.
The Yamaha logo on the real IEMs is black, not white, and they look much less shiny than on the brochure.
I'm 90% sure they're just aluminium, with a hardcoat to prevent scratches and oxidation. It is just easier to mass-produce this way.
I could check at my work, but I'd have to damage the IEMs to collect a piece of metal below the hardcoat.
How so? Aluminum is a very hard and strong metal. I hope you're not thinking of soda cans : P. Although the significantly lower density of aluminum means it can be more easily scratched by say steel objects, it would still be pretty hard to destroy physically(scratching does not equal crushing or denting). I'd rather have the lighter aluminum then the much heavier steel. They actually went with the more expensive material(in regards to stainless or other alloys of steel vs. aluminum) for the housing.
Would it really need a coat of a different material to prevent further oxidation? Note, I'm not arguing with you. I'm just curious since you're a material scientist.
One thing that surprised me today.
I ran these straight from the hp on my fuze today, and they're actually hard for it to drive.
Ok it managed fine but i had to crank the thing, never expected micro drivers to be like that at all.
Btw does anyone know of any replacement tips?
I asked audio affair but no such luck, i might fire an email to yamaha later on.
