Jabra BIZ 2300 Duo QD Wired Headset - Headband Only

Built to survive the contact centre, engineered for crystal-clear conversations.

The Jabra BIZ 2300 Duo (2309-820-105) is a premium, professional corded headset designed specifically for high-volume contact centres and busy office environments. This "Headband Only" version is the perfect replacement or upgrade for users who already have a Jabra Quick Disconnect (QD) cable, providing world-class sound and industry-leading durability.

Breath-Resistant Noise-Cancelling Microphone

Deliver a professional experience on every call. The BIZ 2300 features a state-of-the-art noise-cancelling microphone that filters out background office chatter, ensuring your customers only hear your voice. The "breath-resistant" design features many small holes and a layer of foam inside to prevent unwanted "popping" noises from your breath.

Unmatched Durability (360° Boom Arm)

Built to withstand the rigours of a 24/7 contact centre, the Jabra BIZ 2300 is made from Kevlar-reinforced materials to prevent cord breakage. The boom arm is designed to rotate a full 360 degrees (FreeSpin™), allowing users to adjust the microphone exactly where they need it without the risk of breaking the arm.

All-Day Comfort and Stereo Sound

The duo (binaural) design provides high-quality stereo sound, allowing you to stay fully immersed in your conversation and block out distractions. With its extremely lightweight construction and ergonomic headband, the BIZ 2300 is designed for long shifts and maximum agent productivity.


Key Features:

  • Duo (Binaural) Design: Stereo speakers for total focus and immersion in loud environments.
  • Quick Disconnect (QD): Requires a QD-to-USB or QD-to-RJ connection cable (sold separately).
  • FreeSpin™ Boom Arm: Unbreakable 360-degree rotation for ultimate flexibility.
  • Air Shock Microphone: Specifically designed to reduce respiratory noise and "pops".
  • Kevlar® Reinforced: Built to last with high-strength materials that survive daily office wear and tear.
  • HD Voice / Wideband Audio: Lifelike conversations with superior sound quality.
