Product information

The Jabra BIZ 2400 II Mono 3-in-1 Corded Headset is part of the brand new Jabra Biz 2400 II series which has improved on an already market-leading headset. This product provides the very best in sound quality, acoustic protection, comfort and durability, whilst retaining all of the great features of its predecessor.

The BIZ 2400 II delivers the very best sound quality, with HD voice and HIFI sound. Adding to this, Jabra have installed a high quality noise cancelling microphone that uses DSP to filter out background noise, making sure that your conversations have the clarity and free flow that is so crucial in the modern business. PeakStop™ technology gives you achoustic protection by removing loud harmful sounds before they reach your ears.

The microphone has been specifically designed to reduce the sound of your breathing in conversations. Instead of one large hole in the microphone, this headset has lots of smaller holes and integrated foam protection to make your conversations sound as natural as possible.

A luxury leatherette ear cushion and extra headband padding means that that this headset is designed for intensive use, whilst keeping the user comfy  and productive. This headset is a one ear, over-the-head device, which is perfect if you need to keep an ear free to listen to what is going on around you.

The monaural version comes with three comfortable wearing options to suit all styles - it can be worn over the head, with a comfortable anti-tangle headband, over the ear, or round the neck.

This product is made to last. Jabra's FreeSpin microphone boom rotates 360° and is vitually unbreakable, whilst also allowing you to place the boom exactly where you want it. Added to this, the headset is made with Kevlar-reinforced cords, which is the material used for bullet-proof vests. This means that the Biz 2400-II series are more durable than ever, and represent a solid, long-term investment.
