Thanks for the feedback. That's unfortunate they are very sensitive for proper fit, but I guess most all IEMs are. One of the things I liked about the Audeze in-ears is that you weren't required to jam them into your ear canals like other IEMs, as detailed in this Audeze-produced video:LCD-i3 are very sensitive for proper fit, so take your time and play with other tips sizes and types. Also the way you are wearing them is important. I didn't perceived them as thin and with little bass impact unless too small tips were used. I suggest to try Cipher BT - is a bass booster for this series - and angles earhooks for the best stabilization and leveling the headphones towards ear canal properly. You can help yourself with bathroom mirror and see if i3 are more horizontally aligned or hanging down.
As for EQ, unfortunately I cannot provide any useful data here. If you are using mini jack 3,5 mm and for example foobar, Reveal+ Free can help.
A couple followup questions:
1) What are the advantages of the grooved eartips? A more secure fit? Any audio quality advantages?
2) With the wired lightning Cipher V2 cable, is it limited to 24/48 like the Apple dongle? Per the Amazon Music HD app, that is the highest resolution capability of the device. Maybe that is an iOS limitation, I assumed the Cipher cable would support 24/96.
