Features
Features	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 Biz 2400 II has a superior noise-cancelling microphone that helps eliminate the background noise to give a better customer experience. 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. Better design Jabra Biz 2400 II 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 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 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.
