I am hoping my ears are just as aged and don't mind the treble.
I have heard the treble will put holes in the side of your head, the mids are so recessed you can hardly hear them and the bass is non-existent.
Hopefully, my experience is a lot better than that.
I am not a huge fan of closed backs but the Radiance are wonderful! When I need isolation from either side of the headphones, I am happy to put them on.
My birthday is on Saturday so I am going to have a few drinks tomorrow and hopefully explore my new cans.
