The fit, comfort and optical performance of hearing aids are improved with these earplugs. Rayovac earplugs are lightweight, weighing 60 grams, made of silicone and transparent in colour, making them more discreet than usual. They have a medium size, aimed at people with ear canals of conventional dimensions. Their design is universal, so they fit any type of hearing aid. They are less expensive than the usual models, but still maintain or exceed the quality and durability of the other alternatives. The fitting procedure is simple, almost intuitive after you've done it a couple of times. Once you use them, you won't want to be without them.
