IEMs - Moondrop Aria, because they have a single, pretty good 10mm dynamic driver without the usu. 'huge cluster of balanced armature drivers' per side... i.e. hopefully put the cost where it matters.
V early impressions - I am liking them quite a lot; lots of 'hear-through' goodness, very good control/detail in the bass for the price paid (and a welcome change: good extension with control, in preference to sheer wretched-excess in level which is so common). and no fatigue after several hours listening.
Also - they seem to do dynamics properly, a thing that BA-based IEMs I've heard like the ZS10Pros just utterly-fail-to (which is weird given the high sensitivity - once you hear how compressed/ constipated the ZS10pros are with good material ..well, I cannot un-hear it. and that was with a ludicrous, drive-anything headphone amp of my own devising, as well as a Mojo.)
My preference is always fullsize/over-ear cans, but going to give these Moondrop things a good listen for casual / on-the-go use.
