Monster Bluetooth for exceptional sound quality Powerful Pure Monster Sound® Design optimized for comfort

Monster Authorized Dealer, 1 Year USA Warranty STAYS IN YOUR EAR: The problem with a lot of headphones used for sport is that they fall out - usually exactly when you don't want them to. Monster's patented Sport Clip system is water and sweat resistant and keeps the headphones firmly in place through your most rigorous workouts. This headphone comes with one universally sized clip for ultimate fit and flexibility and you get a choice of 3 in-ear buds for the best possible comfort and in-ear seal. HIGH SOUND ISOLATION: The secure fit of the iSport Achieve gives you 90% noise isolation. A higher level of noise isolation means you won't be distracted by noises around you, allowing you to focus all your attention on your personal goals. We take your safety while training extremely seriously and would recommend these headphones be used in a safe environment.
