For use with E-Scope (Z47862). Headphones have bass emphasis and mono input. Volume control on a central-slider switch. Bridge is worn over the head or behind the head. These headphones allow the user to leave their hearing aid(s) in place while listening. The headphones go over the top of their ear canals or ear molds, thus not interfering with the hearing aid(s). The E-Scope is successfully being used with In-the-Ear (ITE), CIC, and Behind-the-Ear (BTE) hearing aids with these headphones. BTE hearing aids will need to be adjusted by an audiologist for optimal use - increasing the gain of low frequency improves heart sounds and they will need to disable automatic noise reduction. 3.5 mm plug. Allow extra delivery time.
