Built tough in a metal aluminum housing with crystal clear sound, the Metal Bluetooth Rugged Earbuds will hold up against it all. Take them to the gym, while you walk to class, or on your next flight and they’ll provide you with 6 hours worth of jams. Charge them up again and be right back on the go. Utilize the in-line controls to play, pause, track forward, track backward, and adjust the volume as you GO. Their built-in microphone allows you to take calls quick and simple. With everything you need right in an earbud, why need anything else?
