Painful question here. I've been hearing a lot about the smoothness of the 650s, as well as their warm tone and rich mids. However, as much as I enjoy jazz, I'm wondering if these cans'll such the energy out of the music. A lot of jazz I listen to is fusion, or very high energy, and when I look to get headphones, I want something that'll mingle well with my music taste. Not only do I listen to a ton of jazz, but I'm also a massive fan of Yes's old stuff, like Roundabout and Heart of the Sunrise, as well as old Kansas, like Song for America and Wayward Son. I need to know of the HD650 can keep up with the crazy energy of my music, which will ultimately get a decision out of me.
I don't doubt the quality of sound, nor the distortion, response, or anything else, I'm just doing all the research I can to find out what'll end my hunt for the best (affordable) set of headphones on the market that suit my taste and stop me from trying to buy anything more expensive or similarly priced.
