Suunto Sonic headphones are bone conduction headphones with open-ear style, allowing you to listen to audio and still hear your surroundings during exercises.
For the proper experience, put the headphones to the back of your head, with the hooks on your ears so that the transducers rest in front of your ears. Keep the back of the headphones parallel to the ground.
Whether you are training in the gym or you are out on rugged paths, the headphones stay stable on your head. Thanks to their light weight and the open-ear style, the headphones are comfortable to use for several hours. You can wear Suunto Sonic together with a bike helmet or a hat and even under a beanie.
