Here at GirlsGoneSporty, we're big fans of gadgets that make fitness monitoring easier. That's why we were pumped to try out the NB639 heart-rate-monitoring earbuds. These cool headphones feature...well, headphones. But they also track your steps, distance traveled and calories burned. Plus, you can place your index finger on the heart rate sensor to get a heart rate reading anytime during your workout.
The best part about the headphones is that when you want to hear your workout progress, all you have to do is tap the monitor and a digital voice recording will tell how you're doing. This means you don't have to slow down or stop to see the reading on your watch. You can also download your workouts into the free fitness tracking software to keep a record of your progress. The NB639 Earbuds are available at iHome for $99.99
