Can I ask your opinion please? I'm going to get a set of the ACS (UK) custom ear gels, but can't decide whether to have them fitted to my Shure SE530s or to buy a new set of Etymotic HF2s.
I use an iphone so the hf2 microphone would be neat, though I do have the Shure mic unit anyway. I also use a Ray Samuels Predator headphone amp for more serious listening.

So ... put the customs on the Shure's or the Ety's? I know sound is a subjective thing but just would appreciate another view as I've not heard the Ety's in action. Thx.
