SolaceShield Height Extension The SolaceShield Height Extension is an add-on piece designed to add extra height over the hearing aid, allowing hats and helmets to slide smoothly over the SolaceShield instead of pressing directly on the hearing aid. This added clearance helps reduce pressure, discomfort, and feedback that can occur when headwear makes contact with a hearing aid. Because every person’s head shape, hearing aid placement, and sound sensitivity can vary, the Height Extension allows users to adjust the space over their device for a more comfortable and personalized fit. Available in Small, Medium, and Large sizes. Sizing Extension sizes are designed to accommodate different hearing aid placements and comfort needs. Small: 24 mm to 28 mmMedium: 24 mm to 28 mmLarge: 28 mm to 32 mm
