Currently have Dr. Dre Beats. (They were a gift). I was wondering if it would be worth selling them, and buying the headphones mentioned in the title (HiFiMan RE-262). Also, if I could get enough money for the beats to purchase them. They are used, but have 0 signs of being used. Would also be curious on sound improvement, if any. I know these are IEMs, and Beats are On-Ears, but I wouldn't mind the change.
