The Tevo Runner earphones are made for active people. First off, it has shorter cables to the earphones for unobstructed mobility from dangling cables. Next, the sound isolation earbuds are a snug fit with its flexible skirting which makes the earphones stay put in your ears even if you’re violently jumping around. The unit comes with a handy sports wristband for wiping off sweat. Sound quality from these earphones is only average as details are somewhat muffled. Bass is deep, but without complimenting clarity, it doesn’t stand out.
