      Position one speaker over each ear with the band going over the top of your head, just as with a traditional pair of headphones.
      Adjust the microphone by rotating it around the headset and flexing the boom arm until it is positioned less than 2 cm (3/4") from your mouth.

  • Is there a difference in sound quality using leatherette vs. foam ear cushions?

    Leatherette ear cushions provide better acoustic coupling between the ear and the headset. Since less sound escapes, the perceived volume is higher. To minimize the loss of volume, foam ear cushions are made of a special closed-cell foam, which helps improve acoustic coupling. Leatherette ear cushions provide approximately 6 dB extra output. The availability of both leatherette and foam ear cushions is dependent on the model/style/design of corded headset you are using.

  • Are Jabra headsets safe to use?

    Yes, it is safe to use Jabra headsets. All Jabra headsets feature PeakStop™ technology, which protects against sudden loud sound spikes. Many acoustic experts define acoustic shock as being exposed to a sound of over 135 dBSPL, but even lower sounds can damage the hearing. Therefore all Jabra headsets cut off sounds at 118 dBSPL (RMS).

  • How does a noise canceling microphone work on my Jabra corded headset?

    A noise canceling microphone filters out unwanted background noise. It does so by differentiating between sounds that come from nearby sources, such as from the mouth, and those from far away, which are then eliminated. Because of this, it is important that you position the noise canceling microphone close to your mouth, no further away than 2 finger widths.

  • Installation

    • Why am I unable to connect my Jabra headset to my phone?

      Most Jabra corded headsets have a proprietary "Quick Disconnect" (QD) flat connector. This will not connect to a phone without an additional adapter cable. This design allows one headset to be used for multiple purposes.

      • A 2.5 mm adapter
      • Smart Cord adapter
      • USB adapter
      • Etc. 
      These additional adapters/cables must be added as a separate component. Contact your supplier to see which adapter cable is required to meet your needs. If you have a Jabra headset ending in a USB connection, it can only be used with a computer.

    • Will my microphone boom rotate for wearing on my left or right?

      The microphone boom arm is designed to rotate only 270 degrees to protect the parts inside for optimal lifetime longevity. The 270 degree movement can be done in both directions, supporting left and right wearing styles. For 360 degree rotation please select the Jabra BIZ 2400 Series.
