First up, I love my Pathos Converto MK2 and Focal Elegias but, they tie me to my PC in the study. What I would like is to be able to listen to music in the lounge with my feet up sometimes. I am considering a Dragonfly Cobalt and Shure SE425s. Based on reviews they should provide sound quality that will keep me happy, the kit I am using has set my expectations high and, reviews suggest the SE425s have good noise isolation, whilst being wired and without ANC. Any thoughts, especially with regard to possible alternative IEMs? That the SE425s are not the latest thing doesn't bother me. BTW, at first I will be using my Samsung Galaxy S8 then, later on, an iPhone 12, also the budget for the IEMs can be higher if it's going to make a nice difference.
