We’ve refined and improved the BIZ Series headset to not only keep ahead of a changing industry, but to define it. The Jabra Biz 2400 II is our best contact center headset yet.

Better conversation

The most important function of a contact center headset is eliminating background noise from the busy environment and letting the customer hear your voice clearly.

The ultra-noise-cancelling microphone provides the highest degree of background noise elimination in any of our headsets.

Better sound

If you’re in a busy environment, you need great sound to hear the voice of your customer. Additionally, when you’re concentrating on work, you want that HIFI sound for music. The Jabra Biz 2400 II is great at both.

  • HD voice technology makes sure you clearly understand the other party
  • The speakers reduce ambient noise, so you can focus on the call
  • Specially designed “air shock” noise-cancelling mic filters out sharp breathing sounds and popping noises often heard in conversations.

Noise-Canceling Microphone

Noise-cancelling microphones reduce unwanted background noise and are ideal in crowded and noisy open working environments.

Air shock microphone

Having the mic close to your mouth can cause unwanted breathing noise. To reduce this, we’ve designed the mic with many small holes and placed a layer of foam on the inside. This prevents most air shocks and improves call quality.
