I would really recommend these. I previously used KZ Castor, but these IEMs are a major upgrade. The sound division is really good. The only issues are low bass and high treble. If you want a more balanced or v shape, it is better to use an equaliser. I am using these with Fiio K1 and Audiocular X Tiandirenhe CS-PRO DACs. Both give a nice output.
I don't know if this is specific to Apple Music or IE 200, but when I push the music through an equaliser, I hear a crackling sound (only on hi-res, 24-bit/192 kHz). I will maybe test more on this and will update the review.
Finally, I would recommend it. These IEMs are worth the buck.
