easily

SOLD!! I have a seat that I sent to Spencer to have reworked (just the rider portion) - Great condition! $125 shipped (CONUS only!) (I put heat reflective tape on the underside - can easily be taken off - As seen in the 3rd pic below)

Any suggestions for headphones that A. Sound good B. Protect my hearing on the freeway C. Fit easily in a motorcycle helmet D. Work well for running too ?
