Thin enough to fit under a helmet or stylish on its own. Adjustable speakers allow the flexibility to change their placement based on your activity. Slide the disk over your ears to fully engage or position the disk partially behind your ears to be aware of your surroundings. This beanie is the ultimate way to listen to music while being active.
