Hi Mark . Great reveiw I agree with every word. Did you amp them? They don't sound good out of an iPhone or dap. Improve with Hugo or Mojo. Really sing when fed from Vorzuge Pure ii . I use iPhone to Pure on the go and really happy with the sound. At home Hugo> Pure> Eq-8 stunning! The Vorzuge is a far better amp than the Hugo and Mojo.? If you can please try the Pure ii or Pure ii+ with these and I think you will have to question whether the need to spend more on iem. I'm over the moon with them.
