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

Better conversation

The most important factor in 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 noise 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, sometimes you’re concentrating on work and want hi-fi sound for music. The Jabra Biz 2400 II is great at both.

Larger ear cushions* offer better protection against passive noise 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.

Better build

Jabra Biz 2400 II is built to last in a high-performing contact centre, meaning fewer headset replacements and less downtime for you and your team and lower total cost of ownership.

  • Reinforced cord is built to withstand the contact centre environment and protects against office chair wheels, sharp objects and daily use
  • The boom-arm can be rotated 360 degrees with zero risk of breaking. We call this FreeSpin™.

Better comfort

The Jabra Biz 2400 II has an extremely lightweight and unobtrusive design. This means lowered agent fatigue and more productive calls.

  • 40% lighter than competing high-end headsets
  • Adjustable headband and microphone boom-arm lets you find the perfect fit
  • Control unit lets you change volume, mute your calls and more
  • PeakStop™ technology removes sudden loud sounds or tones before they reach your ears: Any sound above 118 dB is filtered out before it reaches the agent.
  • Super-soft leatherette head and ear cushioning
  • Larger ear cushions *

Features at a glance


PeakStop™ instantly removes any harmful loud sounds before they even reach your ears. This keeps the sound level in the safe range and protects your hearing.

Talk in Comfort

Find the perfect fit with a range of light, ergonomically designed frames, larger*, soft leatherette ear cushions, adjustable headbands and microphone boom. Your headset will be comfortable all day long.

HD Voice / Wideband Audio

HD Voice lets you have lifelike, vibrant conversations. You will not 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-cancelling 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 noises. To reduce this, we have 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.
