Ear tips for hearing aids. I recently purchased these, but my mother didn't like them after trying them once, so I'm selling them. Please refer to the photos for instructions. Weight including the case: 44g. Dimensions: approximately 5cm (height) x 6cm (width). The earphones weigh only 3g each. They are rechargeable and cordless, and can be charged simply by placing them on the main unit. The charging status is displayed on the black area in the center of the container.
