A lot of people like to exercise with music on. Can you blame them? It helps to focus the mind and push people to the limit! Speaking about pushing things to the limit, here we have a fine set of Flash Symbol Noise Reduction Earphones which is based on all of the characters to ever have the Flash name! The Flash(es), or sometimes called Scarlet Speedster(s), owe their super powers to a unique source - the Speed Force! You know those guys do a lot of running, so they get plenty of use out of the Flash Symbol Noise Reduction Earphones! The noise reduction helps to muffle the constant sonic booms and are compatible with Iphones, Ipads, Ipods, and other audio devices!
