They can be if they match your preference. To me, they have a beautiful midrange but aren’t fun, so I don’t reach for them often. But it’s all subjective.

Meze Elite and ISN EST50 from what I own.

FiR Xenon 6 or EE Odin if I can pick any IEM.

Just watched Akros review on it. Interesting with the resonance chamber.

Yeah, RF headphones. Sennheiser makes some as does Sony, along with several other brands. Have never used them personally.

Thanks, only one around that I really trust and they’re the ones who suggested I take it to the dealer. I just called them and explained everything… they said they’ll do some research and get back to me, but I should bring the car over when I can.

If you don’t hear it on other headphones, it’s likely a channel imbalance that missed QC.

As far as personal preference vs. how headphones are tuned, I enjoy different headphones for their differences in tuning. The only EQ I do is add a bass shelf to most headphones, but other than that, I appreciate them for their unique sound signatures.

There is, occasionally, a headphone that is completely unlistenable and I don’t keep those.
