Description

Functional Description

ReSound ESSENCE is a strong new family of hearing instruments. With the capability to compensate for mild to severe hearing

losses and state of the art technology in its clase, the ReSound ESSENCE BTE is able to offer excellent hearing solutions.

ReSound ESSENCE is based on the latest chip technology and offers a surprisingly great package for any budgets without

compromising quality or benets. The instrument provides outstanding sound processing and quality as well as better speech

understanding with the very fast WARP system, Noise reduction and a xed Directionality. The strong ReSound DFS system

option of Open Fitting to allow more comfort and easier tting. Overall, ReSound ESSENCE offers a simply surprising product

feature set for better sound quality and more comfort.
