FAQs

What is passive noise cancellation?

Passive noise cancellation uses the headset's physical design, like the earcups and materials, to block out external sound. It doesn't use electronic components to actively reduce noise.

Is this headset compatible with my computer?

This specific model (BIZ 2400 II Mono NC W) uses a Quick Disconnect (QD) connector, typically for deskphones. For computer use, you would need a separate QD to USB adapter or a different headset model designed for USB connectivity.

How do I clean the ear pads?

Gently wipe the faux leather ear pads with a soft, slightly damp cloth. Avoid using any harsh cleaning agents.

Can I use this headset outside of Japan?

This headset is designed for Japanese voltage (90-110V) and plug types. To use it in regions with different voltages, you MUST use a compatible voltage transformer. A simple plug adapter will not suffice and may damage the device.

What does 'Monaural' mean?

Monaural means the headset has a single earcup, designed to cover one ear. This allows you to hear your audio clearly while still being aware of your surrounding environment.

How durable is the cord?

The cord is reinforced and designed to withstand the rigors of a contact center environment, including protection against office chair wheels and sharp objects.

What is Jabra PeakStop™ technology?

PeakStop™ technology automatically removes sudden loud sounds or tones above 118 dB before they reach your ears, protecting your hearing.

Troubleshooting

No sound from the headset

Ensure the Quick Disconnect cable is securely plugged into both the headset and the phone/amplifier. Check that the headset is selected as the audio device on your phone. Test the headset on another compatible device if possible.

Microphone not working or low volume

Verify the microphone boom arm is positioned correctly near your mouth. Check the mute function on the headset or your phone. Ensure the QD connection is secure. Clean the microphone opening gently.

Poor audio quality or static

Check the QD connection for looseness or damage. Ensure the headset is not too close to sources of electromagnetic interference. If using with a phone, ensure the correct audio settings are selected.

Headset causes discomfort

Adjust the headband for a snug but comfortable fit. Reposition the ear cup to ensure it covers the ear properly. Try using the different wearing styles (head-band, ear-hook, neck-band) if applicable and available for your specific model variant.

Pros and Cons

Pros

  • Exceptional call clarity due to noise-cancelling microphone and HD Voice.
  • Comfortable for long wearing periods due to lightweight design and soft ear cushioning.
  • Durable construction for longevity in demanding environments.
  • Passive noise cancellation helps users focus on calls.
  • FreeSpin™ boom arm prevents breakage, allowing 360-degree rotation.

Cons

  • Designed for Japanese voltage (90-110V) and plug types (A or B); may require a transformer and adapter for use elsewhere.
  • Passive noise cancellation may not be sufficient for extremely loud environments.
  • Wired connection limits mobility compared to wireless headsets.
  • Monaural design might not be preferred by all users for extended wear.

Setup, Compatibility & Care

Setup:

  1. Connect the headset's Quick Disconnect (QD) cable to the corresponding QD port on your deskphone or amplifier.
  2. If your phone does not have a QD port, you may need a Jabra QD to specific phone connector cable (sold separately).

Compatibility:

  • This headset is designed for use with deskphones and UC systems that support Quick Disconnect connections.
  • Important Voltage Note: This product is designed for Japanese voltage specifications (90-110V) and uses Japanese plug types (A or B). Using it with different voltages without a suitable voltage transformer can cause damage. A plug conversion adapter may be necessary for your region, but a transformer is essential for voltage adjustment. Jabra is not responsible for damage caused by improper voltage use.

Care:

  • Cleaning: Wipe the headset and ear cushions with a soft, dry or slightly damp cloth. Avoid using harsh chemicals or abrasive materials.
  • Ear Cushions: The faux leather ear pads can be cleaned gently with a damp cloth. Replace if they show signs of wear.
  • Boom Arm: Ensure the boom arm is stored in a neutral position. The FreeSpin™ feature allows for 360-degree rotation, but avoid forcing it beyond its natural range.
  • Cord Management: Keep the reinforced cord untangled and avoid sharp bends or pinching to prevent damage.
