Hearing aids for audiophiles?

I am hoping to get responses from people that have /do wear them or have experience, family members that wear them.

Do you wear hearing aids by chance? 

For those of you that use hearing aids for day to day use... What effect does it have on your music listening  when you take them out. Does the music become veiled, muted, dull?

Here is a little test. While listening  cup your hands behind your ears . . Note what happens to the sound. Then take your hands away and hear the difference. . My wife says there is no difference to her,  but there is a definite difference for me. More highs with my hands behind my ears. 

Some great information and promising too! I Beleive mine is genetic also.

Thanks
