How is the size and fit of the E12 as compared to your Xe6 and Rn6? could you post some pics of the IEMs side by side? I was going to order the E12 but wasn't too much of a fan of the Gold and Rainbow logo options. The Rainbow logo does look more silver than I initially thought so I might get it later down the line. I did consider ordering the E12 but due to the Black Friday 20% off deal going on for all FiR IEMs, I decided to get a universal Xe6 earlier this week. Can't wait to see if the Xe6 will appease my need for more warmth than I get with my Rn6 on gold module. How is the bass of the E12 as compared to Xe6 and Rn6?
They fit similar other Frontier UNIEMs and visually a tad thicker shell.
Ja the rainbow effect on E12 and FiRry logos when viewing front on is subtle. When angled, the rainbow effect is more visible which works well with default faceplate. Still waiting for my custom Obsidian Sparkle + rainbow E12-FiRry logo.
XE6 is more mid-bass and RN6 more sub. E12 leans Rn6 in bass but with more prominent bass and sub depending on track if that makes sense. E12's Tactile Bass adds some nice weight to vocals and hint of fullness in lows. I hear E12 more V than RN6's warm balanced reference sig.
