[Great if you can't stand earbuds] It would rest outside of your ears instead of within the ear canal. Ergonomic design of this headphone when you are on the treadmill, it stays in place so much better than earbuds. Wearing these with glasses is still comfortable. Would not getting ears ore like with earbuds [Extremely lightweight & compact] The headphones are light enough that you don't even notice them when go for a run with them on which makes running easier to get through with my music shuffle. Use these earphones for backs packing and in the gym. Can easily put them in the pocket. Can wear them with your head on a pillow or under a hat [Easy to control music & calling] Over the ear headphones have 4 control buttons, not two like in-ear ones. The right-hand earphone has controls to pick up calls, raise or lower volume, and skip ahead or go back a bit. Each button is indicated with a raised dot but if you take a minute to situate your finger on the dial it's easy to navigate. Experience true hands-free calling and enjoy music on the go. Calling is in stereo, call quality sounds like when you are holding a phone [Extend usability battery life with top notch sound] Headphones are arrived fully charged and ready to go out of the box. Use it several hours a day and charge it on Monday, the battery would last the whole week [Perfect headphones for running] Run and share trail with other people/bikes. You want to hear them approaching from the back. Smaller would-be a plus for hot summer runs. You may also like the fact that Sound control is easier this way when your main focus is running
