Olympic gold medal winner and fantastically named, Usain Bolt, has lended his talents to developing customizable in-ear headphones made just for runners by the so called “World’s Fastest Man.” Aptly named “Run-Free,” these headphones are lightweight, sweat resistant, and durable. Flexible ear hooks offer comfortable adjustment to all sizes of ear and make for a secure placement without the constant worry of wiggling out that in-ear canal only buds do. The sweat resistant straight wire cable and Apple controller offers complete control over music playback coming from smartphones via bluetooth. The controls sit about collar level and clip onto your shirt. It comes with the usual reliability of SOUL electronics headphones, rich sound, great drivers, deep bass. Comes with a carrying case and is iOS compatible, in two colors, black and black/green in tribute to Jamaica, Bolt’s home country. If it works for him, it’s gotta work for my morning jog. Available for $169.95 at SOUL.
