Is the treble a little high?
I feel the high notes are piercing through my ear canals...not very natural sound for some reason.

the treble on the RE0 extends very far but is not sharp at all. i find it very smooth, unlike some other IEMs like the TF10 and CK10 whose treble can be a bit sharp at times. the treble on the RE0 is the best i've ever heard from an earphone, perfect balance of extension, focus, and smoothness. i do not find it fatiguing at all.

EDIT: maybe i should clarify here: the treble on the RE0 is VERY good, however, there are many things that other IEMs do better than the RE0. for example, the bass and mids on the CK10 are better than the RE0, while the imaging and resolution (speed/separation) on the CK10 far surpass that of the RE0.

Thinksound Rain has smooth treble and is generally very unfatiguing, yet resolving.

Even after doing the foam mod (which brightens the treble and brings the mids forward), I don't find the RE0s treble to be overly sibilant or sharp. Perhaps my ears are less sensitive to that sort of thing.

How long have you been listening to them? I believe that the treble calms down a bit (without losing clarity) after burning them in for a long while.

Going to have to agree with Eraser here on the treble. I really don't find it sharp at all. It's strong and present but smooth at the same time. It is for sure more prominent than in some other iem's but not sharp at least for me.

He said he fixed it by doing a foam mod. I didn't try this myself, but I agree that strings and an electric guitar on the stock version can sound harsh.

If anyone wants to compare, listen to Mammatus' "The Righteous Path Through The Forest Of Old" with the RE0.

I've never heard this spike 14kHz spike in mine. No sharpness or harshness in the treble.

One could try repositioning the foam inside until the treble is non-fatiguing. Or removing it.

 

[EraserXIV]

removing the foam is not what you want IMO. in my experience it changes from smooth and unfatiguing to sharp and slightly fatiguing.

I don't find the treble to be harsh or fatiguing at all which to me is quite a feat given the treble-centric nature of the RE0's presentation.

Brightens the treble on the RE0?!

 

[rawrster]

I kinda wish I tried out the foam mod before I sold the RE0. I probably was the only moron would couldn't figure out how to remove the filter lol =(

the foam mod does bring them quite close to the CK10 in terms of sound signature.

He must mean removing it, instead of changing the type of foam, repositioning it, or adding more.

This is my foam mod.
I find the mids a little warmer and highs smoother. Very nice.
Also a bit more kick in the low end.
No fatique or harshness with this setup.
