JLab seeks to up the game with every new generation of the best-selling JBuds line, and the J4 Rugged Metal Earbuds Style Headphones are no exception. Building on the sleek style, premium sound, and maximum comfort of the bestselling JBuds J3 earbuds, we gave the new JBuds J4's a flexible exoskeleton armor over all components for extreme durability and a hot new rugged look. These cans are built to last!The J4 ear buds also feature a rock solid, heavy duty aluminum housing, tangle-free flat cables with kevlar reinforcement, eye candy 3D logo details, and an extra tough EVA carrying case with room for your J4's and an iPod nano or shuffle. The J4's also include 7 pairs of custom molded earbuds cushions, in both single flange (XS, S, M, L) and double flange (XS/S, S/M, L/XL). The J4's are arguably the most rugged and durable earphones ever made. They're the perfect solution for those seeking an extra tough, heavy duty pair of ear buds with the legendary JLab sound: balanced wide range response, tight bass, and crisp clarity. The J4 is available with and without a mic in a range of bold, stylish color combos. Compatible with all iPods, iPhone 3G, 4G, HTC, Blackberry, Kindle, iPad, laptops, and any device with a standard 3.5mm jack. For those seeking ultra lightweight, slightly slimmer earbuds, you can't beat the JBuds J3, for iPhone 1 and 2 owners, we recommend the J3M.
