Most of the major hearing aid manufacturers now build instruments with connective capability. I prefer GN ReSound Alera with Unite wireless accessories. These devices can make the difference between the patient understanding or not understanding what they hear. Eliminating distance, space, and room acoustics by using a direct wireless connection between the hearing aids and the audio source provides an amazingly clear sound. Almost every time I demostrate this technology the response is......WOW. Its so clear.
