More experienced owners will be along with more helpful info but I’ll start the ball rolling by suggesting that you order them for a 30 day in home trial. No better way I can think of to evaluate them.
I’m not an audiophile but a friend of my records and produces music for some local bands. When he came over and listened to my M80s he said that they didn’t sound bright to him in my room. He tested them with music he had recorded in his studio an felt that people might be mistaking their accuracy for brightness. He called them unforgiving when listening to some of his lesser quality recordings
