Listening to the kind of music that motivates you while doing exercise has a proven effect on your results. Good sports headphones must be light, comfortable and feature a lengthy battery life. Several types feature a cable which goes behind your neck, and these are good for the gym. Completely wireless headphones aren’t as distracting, and since they’re perfect for running, these might be your best choice. Some also feature various exercise apps including heart-rate monitors that can also function as a fitness tracker, and these can be sweat or water-proof. With that in mind, you’ll have a tireless companion to motivate you when training.
