2291 / 2291V

Low Output, Hearing Aid Compatible 150Ω Earphone

The 2291 earphone is primarily designed for applications where a lower output level is desired.

This element is available with an optional click-suppressing varistor (P/N 2291V). The purpose of the varistor is to protect the users' hearing by limiting the maximum output of the earphone element, and is a uL requirement for some applications.

Elements are available in a variety of custom impedances that may require minimum purchase quantities and varying lead times - contact our sales department for more information and pricing.
