Evolve 30 II mono replacement headset

The Jabra Evolve 30 II replacement headset mono 14401-20 is a wired, single-ear accessory built for professional workspaces. It connects through a mini-phone plug and uses an over-the-head band for secure fit during long calls. Designed as a direct replacement part, it restores full audio function to compatible Evolve 30 series units without needing a new full kit. The mono speaker keeps one ear open to the surrounding office environment.

Suited for single-ear call handling.

This unit suits workers who spend most of their day on voice calls and need to stay aware of colleagues or announcements. It is not for users who want stereo sound for music, multimedia or immersive conferencing. Buyers who need dual-ear coverage or a complete headset with inline controls should look at other configurations. The part only replaces the headset portion, not cables or control modules.

Mono speaker configuration defines the use case

The single mono speaker is the specification that determines whether this replacement matches the buyer's workflow. A mono driver delivers clear voice reproduction while leaving the other ear uncovered for situational awareness. If the user's role requires both ears covered for noise isolation or stereo playback, this part will not meet that requirement. Verify the original headset was a mono model before ordering.
