Unfortunately I haven't heard the R1 but I've got several other Trinity IEM's so I don't doubt that the R1 is V-shaped as well
Here's the graph for the Big Dipper with both bass and mid switch on (courtesy of @Brooko), this is the way I use them most of the time:
As I said perceive them as very well balanced when listening to them, especially bass is very well behaved and does never overshadowed the other frequencies. Still from the graph they're slightly V-shaped.....
The fact that the Hz is missing on the axis on the T12U graph makes it impossible to compare them though. I'd still expect the T12U to have a more present lower midrange and less energy in the upper midrange so they're probably quite different sounding. Unfortunately this also makes them interesting for me
Hahaha, sorry Peter, this is embarrassing. I actually took a snippet from their product page and forgot to include the HZ below:
