Professional Stereo Audio

The Jabra Engage 40 features two 20 mm speakers that deliver clear audio for customer calls, business communications, online meetings, and multimedia. The speakers support a frequency range of 50 Hz to 20 kHz in music mode and 100 Hz to 14 kHz in speak mode.

Dual MEMS Microphones

Two MEMS microphones capture the user’s voice while supporting clear communication during calls. The microphone system provides a frequency range of 100 Hz to 14 kHz for professional voice communication.

Noise-Isolating Ear Cushions

The angled ear cushions and flexible earcups provide a secure, adaptive fit while helping reduce surrounding distractions. This makes the headset suitable for open-plan offices, contact centers, and other busy work environments.

Call Noise Reduction

Integrated noise reduction technology helps minimize unwanted background sounds during calls, allowing agents and customers to communicate more clearly.
