Two or three years ago my mother got me a pair of MMX 300s for Christmas. At the time I didn't think much of it, they were just a comfortable pair of headphones that were good to play video games with. As of about a month ago I started to seriously getting into music, which lead me to research headphones. I did a ton of research and ultimately decided on a pair of mdr-v6. I found that I am very interested in headphones, and I think that I would enjoy the audiophile hobby very much. Back to the topic, I have this pair of MMX 300s, which I read is essentially a pair of DT770s with a high quality mic, and I am curious as to where I go now. I can either get an amp,if I get an amp it is going to be a portable one, or I can get a pair of Grado SR255i (or other similarly priced open ear headphones). If I get an amp, it would have to be $200 or less. So what would be a better investment for my future audiophile endeavors?
Oh,I am going off to college next year, so most of my listening is going to be from my Android Razr Maxx or a laptop I still have yet to decide on.
