Compatibility & Buying Information
Exact Product: This page is for Mitel part number 51310036, the H20 Mono Analog Headset with QD cable. The underlying headset platform is the Jabra BIZ 2400 II Mono 3-in-1, Jabra part number 2406-720-209.
QD Cable Included: Mitel identifies part number 51310036 as the H20 Mono Analog Headset with QD cable. This is important because the underlying Jabra BIZ 2400 II headset uses a Quick Disconnect interface and requires an appropriate lower connection cable for a complete desk-phone installation.
Analog RJ9 Connection: On supported Mitel phones, the H20 connects through the dedicated analog RJ9 headset interface. It is not a USB headset and does not require a USB port.
No Wireless Pairing: The H20 contains no Bluetooth or DECT radio. There are no batteries to charge, pairing procedures to complete, or wireless range considerations.
3-in-1 Wearing Style: The mono headset can be configured with a conventional headband, earhook, or neckband, giving individual users greater flexibility for long-duration contact-center and office use.
One-Ear Design: The mono configuration leaves one ear uncovered, which is useful for employees who need to remain aware of coworkers, customers, announcements, or other activity around them while taking calls.
Noise Reduction: The unidirectional ultra-noise-canceling microphone is designed to focus on the user's voice while reducing surrounding workplace noise, making it particularly useful in open offices and contact centers.
Supported 6900 Series Phones: Mitel currently lists analog RJ9 H20 support for the 6910, 6915, 6920, and 6930 / 6930L. The 6940 is not listed as supported.
Supported 6900W Series Phones: Mitel currently lists H20 support for the 6920W and 6930W through analog RJ9. The 6940W is not listed as supported.
Supported 6800 Series Phones: Mitel currently lists H20 analog RJ9 support for the 6865, 6867, and 6869. The 6873 is not listed as supported.
No Separate Call Controller: Unlike the H30 USB headset, the H20 does not require an Engage Link controller. It connects directly through the appropriate analog headset interface and included QD connection cable.
Best Fit: Mitel H20 51310036 is ideal for contact-center agents, receptionists, administrative staff, customer-service representatives, and other professional users who want a lightweight single-ear analog headset with flexible wearing styles and strong microphone noise reduction.
