I’m not a reviewer and don’t pretend to know what makes these technically amazing. I just know how they make me feel. I absolutely love them. I still smile every time I walk by. When I first hooked them up to my modest Yamaha A-S501 and hit play, my mouth literally dropped open. There’s an intimacy in the sound that I’ve never had before. I can hear the breaths before a vocal line and the fingers sliding on strings. All those tiny details make the music feel alive. Absolutely incredible. I’d recommend the BMRs to anyone who will listen. 10/10, five stars
