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 for those who listen and speak for a living.

Better conversation

The most important function of a professional 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 noisy environment, you need a microphone that eliminates background noise so that the customer hears only your voice. High quality speakers with passive noise cancellation reduce the impact of office noise to enable you to focus on the customer’s voice. Duo headsets will also give more protection from background noise than mono versions. Additionally, when you’re concentrating on work, you want that HIFI sound for music. The Jabra Biz 2400 II is great at both.
Larger ear cushions* offer better protection against passive noise in the contact center to help you focus on customer conversations

  • HD voice technology makes sure you clearly understand the other party
  • Specially designed “air shock” noise-cancelling mic filters out sharp breathing sounds and popping noises often heard in conversations.

  • Boom arm can be rotated 360 degrees with zero risk of breaking. We call this FreeSpin™.

HD Voice / Wideband Audio

HD Voice lets you have lifelike, vibrant conversations. You won’t have to struggle to hear what the other person is saying.


You can rotate the boom arm 360 degrees without the risk of breaking it. Find the microphone placement that works for you.

Reinforced cord

Cords are reinforced and built to last. They’re extremely durable and will take most daily punishment.

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.
*Larger ear cushions come as standard on Duo versions and are available as an accessory for Mono versions. The larger ear cushions are only suitable for the headband version of the Biz 2400 II and not for other wearing styles like neckband.
