Yeah, big no no. The hour or so after I shower is actual headphones time no matter what sort of noise is around me.

I think that’s mostly correct, the thing is that unless you posit a flat curve, the frequency response pattern will be both a product of tuning and an index for detail retrieval.

The way I do it is fairly simpler than what most people generally go for. I play industrial music with vocal distortion. The more detail, the more patterns you’ll identify in the distortion. The less detail, the more “smear” you’ll hear.

Maybe so, but I’d have been ashamed to put my name on a set of iems with such an obvious issue.

It has legit tuning issues. The shape of the IEM cavity affects tuning.

Listen to anything where a resonant filter cuts through something like vocals where the formants cross into both drivers and compare against a good single driver array. You’ll instantly hear how there is some muddy reverberations that remove detail.

Crinnacle is just a kid with a YouTube channel and a website, not a sound designer. If the shape of the IEM cavity is what causes this, Crinnacle should have known better.

My Chu’s are better than the two sets of Truthear Zero’s I’ve already sent back.

People need to stop looking at prices and actually focus on the level of detail an iem can put out and how it responds to EQ’ing. I am not touching any of Crin’s shit if he thinks the design of the TE Zero was proper. It is not.
