Plantronics C435 900 MHz 1-Line Cordless Phone

As people age, hearing loss seems inevitable, especially when living and working in noisy environments. With its unique, built-in amplifification system, the Clarity C435 (featuring Clarity Power Technology) makes phone conversations not only louder, but clearer and easier to understand. Clarity Power Technology increases the volume of high frequency sounds, the kind of sounds many people can¿t hear clearly on the phone.
