Jabra Biz 2300 is a headset designed and developed with contact centers and agents in mind

Jabra Biz 2300 is built to survive in a high-performing contact center, meaning less headset replacements and fewer 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™.
Extremely lightweight and unobtrusive design means lowered agent fatigue and more productive calls.
- Weights just 49 grams (1.73oz) in the mono version, and just 68 grams (2.4oz) in duo
- 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.

Lifelike conversations and higher customer satisfaction require both great, ambient-noise-reducing sound in the agent's ears, and a noise-cancelling microphone that also avoids air shocks. The Jabra Biz 2300 has both.
- 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.

The Jabra BIZ 2300 Mono, NC (2303-820-105) is a single-ear headset with a noise-canceling microphone, designed for people who handle VoIP or other desk-based calls and want to keep one ear free. HD Voice, a 360-degree rotating boom arm, and PeakStop sound protection support everyday conversation.
Recommended For
- Contact-center and call-queue agents who spend much of the day on desk-phone calls and need a lightweight, single-ear headset with a noise-canceling microphone.
- Desk-phone users who need a Quick Disconnect headset and can match it with their phone’s compatible headset cord or adapter.
- Reception, service-desk, and sales-floor staff who want one ear available to hear nearby coworkers or the office while taking calls.
- Office teams looking for a corded headset for frequent speech-focused calls, with a flexible boom arm and reinforced cord for regular workplace use.
Real-World Use Scenarios
- In a contact center, an agent handling a steady stream of customer calls can use the wired mono headset for desk-phone conversations; its noise-canceling microphone is intended to help reduce surrounding office noise picked up by the mic.
- On a busy sales or support floor, a caller can speak with an agent while nearby conversations continue; the directional noise-canceling microphone is designed to make the agent’s voice clearer to the person on the other end, though it does not silence the office for the wearer.
- For desk-phone customer service work, the Quick Disconnect version lets an agent unplug the headset when stepping away and reconnect it when returning, provided the phone uses a compatible Jabra connection or adapter.
- When an agent needs to hear nearby coworkers or office announcements during calls, the single-ear design leaves the other ear uncovered; it is a practical fit for shared workspaces rather than a way to block out room noise.
- During long calling shifts, an agent can reposition the boom as needed and wear the lightweight headset for ongoing conversations; comfort will still depend on individual fit and preference.
- If a call includes a sudden loud sound, PeakStop is designed to limit harmful audio peaks reaching the headset wearer; it is a precaution, not a substitute for keeping listening volume comfortable.
