Jabra Biz 2400 II USB Binaural Corded Headset

The new Jabra Biz 2400 II USB Duo headset delivers outstanding sound on both ends of the call. Weighing 40% lighter than competing headsets with soft leatherette headband and ear cushions, it offers superior audio quality, reliability, and comfort. This headset is built to last with a reinforced cord and 360-degree rotating boom arm.

Better Conversations For A Better Experience

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 Biz 2400 II USB Duo has a superior noise-cancelling microphone that helps eliminate background noise to give a better customer experience.

Premium Wired Headset


Better Sound for Crystal Clear Calls

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.

Better Design to Last For Years

Jabra Biz 2400 II USB Duo is built to last in a high-performing contact center, 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 center environment and is protected against office chair wheels, sharp objects and daily use
  • Boom arm can be rotated 360 degrees with zero risk of breaking. We call this FreeSpin™.

Better Comfort for All-Day Wear

The Jabra Biz 2400 II stereo headset 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 let 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 118db is filtered out.
  • Super-soft leatherette head-and-ear cushioning
