  • The batteries used in Solar Ear’s hearing aids are only 50 cents more expensive than disposable alternatives, but can last up to three years as opposed to 1 week for conventional batteries. Solar Ear’s batteries are also compatible with 95% of all hearing aids.
  • Batteries are charged using a palm-sized solar charger which can also be used to charge cellphones and other electronics
  • The hearing aids cost only about $100 per pair and include batteries and a charger at no additional cost.
