it's actually from 4k to 8k according to this: https://autoeq.app/ (switch to harman iem 2019)
Here you have more correct measurements:

the diffuse field tilt target, especially at -0.8, is arbitrary. There is no science behind it
Yeah, funny that everyone can criticize Harman’s methodology but when it comes time to get dozens of people to do hundred of blind listening test then nobody else is willing to organize and fund the research.the diffuse field tilt target, especially at -0.8, is arbitrary. There is no science behind it

judging science isn't arbitrary, it either has research behind or it doesntarbitrarily judge what is science and what is not![]()
It's a balancing act betweent the bass and the upper mids 2-5kHz area. Red is somewhat relaxed in upper mids and it's already tuned with optimal bass levels stock. If OTOH Red had more upper mids it it would !tolerate" more bass boost.Tbh it is incredible to me that there is a demand for more bass on the RED.
Not only because the bass level already pretty much hits my personal sweetspot, but also because its mid-centric sound signature does not suit high bass levels at all.
It will just be muddy. (Subjective, of course)
Edit: there is an inline resistor which reduces sensitivity some but effectively boosts bass:

There are some trade offs using the adapter. It pretty much tilts the response in favour of the bass- it doesnt just increase the bass.Hey @amirm, unless I'm misunderstanding something, doesn't the graph with the 'Bass+' resistor adapter show a very close match to the target, better than the response without the adapter? It certainly seems to deviate from the target less overall. Yet it appears you prefer the Zero Red without the adapter and assessed it in that configuration. If one is to not use EQ (because the source doesn't support it, say), wouldn't the obvious choice be to use the IEM with the adapter?
preference score without adapter is 82.4: https://www.audiosciencereview.com/...zero-red-iem-review.44865/page-4#post-1598166Hey @amirm, unless I'm misunderstanding something, doesn't the graph with the 'Bass+' resistor adapter show a very close match to the target, better than the response without the adapter?

Haha... the prices are so low that most of us seem to have tried several of them. I came home to find a pair of Truthear Hola this evening. It'll be interesting to compare them with the zeros (both types) but they're at work. For now they sound good and the cable is impressive given that they're even cheaper than the 7Hz zeros. Weird that the ear loops seem to be intended for someone with 20cm diameter, highly protruding ears but a bit of bending should fix that.I have been switching between my favorites, the Truthear Zero Red, and the new 7Hz Zero 2. To me the Red is still the better balanced of the 2 and remains my favorite. While the Zero 2 comes very close, is prettier, more comfortable and costs half the price, one could argue that it is the better value. But paying 25 or 55 usd for excellent sound quality is the same to me, the price difference does not matter tbh.
