DESIGNED TO FIT PERFECTLY These wireless headphones are designed to rest low in the ear, with the cable going over or under your ears. The earbuds are specifically design to stay in position and not fall out. Light with a smooth design make these earbuds extremely portable. Because the earphones sit in the ear canal, they dont affect hairstyles, or interfere with glasses or earrings. SOUND ISOLATION Because these earphones actually get inserted into the ear canal and with the flexible earphone tips a complete seal is formed around the tip of the earphone to isolate the sound and block out noise. This creates amazing sound quality because they create their own closed-off sound environment within the ear. Another advantage of blocking outside noise is that since you don't have to play music loud enough to overcome the din, you can listen at much lower, safer levels. FLEXIBLE & INTERCHANGEABLE TIPS - These tips let you pick the best fit without sacrificing sound isolation. Your earphones tips come in three sizes so you can find the one that fits you the best, or swap them out depending on activity. Designed to keep the earbuds in place in your ears even during activity, with an ear tip attachment that nestles inside your ear while you listen. These earphones with its secure, comfortable fit and exceptional noise isolation, delivers superb sound quality. 100% MONEY-BACK GUARANTEE FOR 1 FULL YEAR Were so confident in our CE/FCC/ROHS Certifications were offering a 100% money-back guarantee.
