These non-waterproof headphones are designed to be used with our Advance Unit. You plug the headphone’s 3.5mm audio cable directly into your Advance Unit to establish communication. We recommend using these on land since they are not waterproof. These are ideal for a coach or team member observing from the shoreline or boat.
From the date of purchase, the non-waterproof headphones are covered for 6 months. Please see our warranty section for complete warranty details.
