In all honesty you'd be better off getting a pair of Beyer DT770 studio monitors which are unmatched in terms of transparency for the price. Unless you're willing to make some significant sacrifices the difference between a set of studio phones and something you'd use in the gym is too vast to find a multiuse pair. If you're serious about studio quality get the horse**** marketing from rap moguls out of your head and pay for real ears.
If you do want a recommendation for good in-ears at a reasonable cost, look into Shure or Klipsch. Bose may be fine for consumer use but they don't even begin to match up to Shure for actual frequency response.
