Great review.
 
1More had a duo driver hybrid before the triple.

Great review, the one thing I don't agree with is where you say that they have the same sound signature.
Because to me they don't sound very similar at all.
 
Your graph also highlights this.

When in comparison between the two IEMs in question here, there is no list of equipment used. We are left in the dark concerning any of the upstream equipment used for these thoughts.

For me it sounds very flat and reference like and I am using a SMSL M8 or Topping D30 DAC w/ Topping A30 Amp.
I also have a fulla2 but haven't had much listening time with that since I got the Topping stuff since its just so much better.

@Jimster480  Not sure if we're looking at the same 2 graphs here - the only difference I could measure is at the 5-10k range, and even then the general curve is very similiar.

@Redcarmoose
 
Apologies. I test them out of a Fiio E07K DAC. 

@alffla Where do you see a graph for the triples which is similar? Because the triples graph has recessed mids.

@Jimster480 from my own measurements.
