Resound Hearing Aid Sport Lock Retention Device For Most All Newer Low Power (LP) SureFit Speakers
This listing is for one (1) retention lock. These sports locks fit many newer Low Power (LP) GN Resound SureFit receivers. The design helps keep the hearing aid speaker firmly in the canal and less visible to others, especially during most physical activity. This lock will wear out over time. It is recommended to replace it every six months or so.
