Jabra Evolve 20 Stereo Headset (4999-823-169)

The Jabra Evolve 20 Stereo is a professional wired headset designed for clear communication and all‑day comfort. This variant features dual‑connectivity with both USB‑C and USB‑A plugs, making it compatible with modern laptops, desktop computers, and devices that use either port. The “Microsoft Version” (MS) ensures native integration with Microsoft Teams and Skype for Business, providing a seamless Unified Communications experience.

Key Features

1. Dual USB‑C / USB‑A Connectivity

Unlike the standard USB‑A only model, this version includes a USB‑C connector for direct connection to modern laptops and tablets. A USB‑C‑to‑USB‑A adapter is also supplied, ensuring compatibility with older computers that have only USB‑A ports. This flexibility makes the headset future‑ready and ideal for hot‑desking or hybrid work environments where devices vary.

2. Microsoft Certification for Seamless UC Integration

The “MS” designation means the headset is certified for Skype for Business and optimized for Microsoft Teams. Call control buttons (answer, end, mute) work natively with the Teams client, giving you a familiar, trouble‑free experience without additional configuration.

3. Superior Noise‑Canceling Microphone

A professional‑grade, noise‑canceling electret condenser microphone is mounted on a flexible boom arm. It actively suppresses background noise (such as office chatter or HVAC sounds), ensuring that remote participants hear only your voice with exceptional clarity. The microphone frequency response (100 Hz – 10 kHz) is tuned specifically for speech.

4. Passive Noise Cancellation for Focus

The on‑ear design features soft foam ear cushions that create a physical seal around your ears. This passive noise cancellation effectively blocks out high‑frequency ambient noise, helping you concentrate on calls or tasks without distractions.

5. Easy Call Management with Inline Control Unit

A compact inline controller puts essential functions at your fingertips:

• Answer / end calls

• Volume up / down

• Mute microphone
  An LED indicator shows microphone status and call state, so you always know whether you are muted or on a live call.

6. All‑Day Comfort and Durable Build

Weighing only 171 g (6 oz), the headset is comfortable for hours of continuous use. The adjustable headband and generously padded foam ear cushions provide a secure, gentle fit for various head sizes. The headset is built to withstand the demands of daily office use with reinforced cabling and robust materials.

7. Reliable Audio Performance for Calls and Music

Equipped with 28 mm dynamic speakers, the headset delivers clear, natural sound for voice calls and sufficient quality for listening to music or multimedia. The frequency response (150 Hz – 7 kHz) prioritizes speech intelligibility, and the 32‑ohm impedance ensures efficient performance with computer audio outputs.

8. Integrated Hearing Protection

Jabra PeakStop technology provides acoustic shock protection by automatically limiting sudden loud sounds that may occur during a call, safeguarding your hearing.
