There's no reason you should still be using the earbuds that came with your phone – at least not when there are options like these out there. They're Bluetooth 4.1-enabled, with a 120 feet range so as not to limit your range of movement, with a ten-hour battery life, allowing you to keep on listening for longer. Perfectly crisp and noise-isolating, the Bolt's sound is exceptional, to say the least. Plus, they're sweat-proof, so go ahead and wear them while working out, running, or anything else active for that matter. Except swimming. That wouldn't work.
