Sophono manufactures implantable bone-conduction hearing devices. Instead of an abutment protruding from the skin, Sophono devices use magnets to attach to the head. It is a great alternative to having an abutment, as there is no cleaning or special care needed for the implant site. The company itself has incredible customer service, responds quickly, and genuinely cares about the clients experience from start to finish. Sophono is a great company with wonderful people and a life-changing device!
