Dap and Angie are a great pairing. Angie is a pretty neutral phones that grabs great, deep bass when it's in the recording which this dap does well. However this dap isn't going to inject bass. Maybe if you EQ, but I have not messed with that.
So the current champion of the tips search is .... One comply "comfort" tip and one comply "isolation" tip, both size large. Good seal with minimal ear socket adjustment. Have to "stretch" the opening a bit to make sure the bore holes aren't covered. There it is. Happy as a clam.
Yes shocking the Verge audience not grasping a purpose-designed device. Having Android on board is more consumer friendly than a boxed in OS. However the OS isn't there to play KOTOR. I'm sure everyone already has a phone for that.
