Wire-free earphones have finally come into their own after a few shaky early years. There are now plenty of wire-free options that are relatively affordable, reliable, rugged, and sound good. Some models have additional fitness features like heart monitoring or vocal coache,Bluetooth earphones let you listen to your music without running a wire to your smartphone. They're pricier than wired earphones, but the convenience can be worth it. However, they need power to work, so you'll want to keep an eye on battery life. Of course, if you keep your workouts to a few hours at most and charge your earphones when you get back from the gym, that won't be a problem.For the gym, you'll generally want earphones over headphones. They're lighter, more resilient, and are often built for exercise. Even if you prefer the sound headphones offer, you'll find that a good sweat can eat through most earcup pads quickly, and the extra bulk on your head is uncomfortable during a workout. This doesn't mean you can't use headphones for the gym. We've seen a few very good on-ear headphones designed to handle sweat, and clean up easily, like the Plantronic BackBeat Fit 500.
