Hearing aids, with their high-tech chips and processors, are like computers you wear on your ears. Due to modern technology, hearing aids include many features such as Bluetooth connectivity, rechargeability, level of amplification needed, lifestyle choice, small designs, speech recognition, and remote control. All of this cost. Part of the cost is also spent on research and development, which is needed to keep updating and improving the technology powering the hearing aids. The rest of it is spent on fitting and dispensing fees, adjustments, customization, warranties, aftercare and future appointments.
