ASI Audio 3DME In-ear monitoring system

I have high quality hearing aids, but am sometimes disappointed with their sound. Sometimes harsh, sometimes sibilance. I was looking for better alternatives for someone with hearing loss and stumbled on the 3DME on a a website called Grand Piano Passion AN OASIS FOR ADULT PIANO STUDENTS AND MUSICIANS WITH HEARING LOSS.

They are designed for musicians, but maybe a good solution for audiophiles with hearing loss. They are analog, have 20-20KHz (although +/- not published) capability and a 7 band equalizer per channel, and are highly recommended by Grand Piano Passion as an alternative to hearing aids. There are no audio reviews, only musician reviews.

I am very tempted to buy these, but have a little pause as they are not marketed nor reviewed for audiophiles, only musicians.

Has anyone had any experience with these? Thoughts?
