Perfect if you don't like earbuds. They sit outside your ears instead of in the ear canal. The ergonomic design of these over-ear Bluetooth headphones means they stay in place much better than earbuds when you're on the treadmill. It's still comfortable to wear them with glasses. They don't poke into your ears like earbuds do. Extremely lightweight and compact. The headphones are light enough that you won't even notice them when you go for a run, making it easier to run with your music on shuffle. Use these behind-the-head headphones for support and at the gym. You can easily put them in your pocket. You can wear them with your head resting on a pillow or under a hat. Easy to control music and calls. The headphones have four control buttons, not two like the in-ear variants. The right earbud has controls for answering calls, increasing or decreasing volume, and fast-forwarding or rewinding. Each button is marked with a raised dot, but if you take a moment to place your finger on the dial, it's easy to navigate. Experience hands-free calling and enjoy music anywhere. Calls are in stereo and call quality sounds just like holding a phone. Extend battery life with premium sound. These behind-the-ear Bluetooth headphones come fully charged and ready to use right out of the box. Use them several hours a day and charge them on Monday, and the battery will last all week. Perfect headphones for running. Run and share tracks with other people/bikes. You want to hear them approaching from behind. Smaller wireless Bluetooth headphones would be a plus for hot summer runs. You might also like that audio control is easier when your main focus is running, making Bluetooth headphones ideal for sports.
