Reply to Torn between two headphones

I have been looking into getting a new pair of headphones and i believe i have finally narrowed her down. Im looking at sol republic tracks HD or Beats by Dre Mixr. the sol republics are $150 and the mixrs are $250. Please leave any advice about which one you would choose and recommend others if you can believe of anything else. Im on a budget of $250 by the way. All responses are appreciated.
