What is missing with mail-order or disposable hearing aids is the important professional service that is essential for a complete hearing aid solution for a patient. In most cases, getting a good result from amplification requires more than just a hearing aid. It requires selecting the right hearing aid and features to match the individual's communication needs. In most cases, a significant amount of fine tuning and problem solving will be needed after the fitting. Although mail-order and disposable hearing aids may have perfectly fine circuitry, they certainly lack the possibility for professional care that is needed for real success.
