Your thoughts on wireless iem's

I'm looking for wireless IEM's. I'd mostly wear them as I go to sleep listening to music. Noise cancellation, is not needed. I'm comfortable with a used pair as well as new.
My criteria is simple
1- Sound quality
2- Comfort
3- Android app
3-Build quality

Perusing online forums, the following seem to pop up.
A) Sony WF-1000XM$
B) Noble Audio Fokus Pro
C) Final Audio ZE3000

Your thoughts & suggestions are appreciated.
