The Jabra BIZ 2400ii Duo corded headset is the ultimate Jabra corded headset designed to be used with your desk phone, smart phone, or computer (each requires the correct connector cable). It has a noise cancelling microphone which rotates to allow it to be worn on either ear. All wired headsets would need a brand and phone specific QD (quick disconnect) connection. In most cases, the Jabra smart cord would have no problems accommodating this, however if you aren’t sure, the information can be checked via the compatibility guide at http://www.jabra.com.au/headsets-and-speakerphones/compatibilityguide or feel free to give us a call or send us an email and our staff will gladly check for you. Positives The Jabra BIZ 2400ii Duo has all the bells and whistles a corded headset can have. It comes with headband, ear hook and neckband to suit any user, plus stylish leatherette ear cushions. The noise cancelling microphone of the Jabra BIZ 2400ii Duo prevents any unwanted noise being heard by your callers, while the flexible boom ensures perfect positioning. Things to consider As with any corded headset, with the Biz 2400ii, you are tied to your phone via a cable, this can be frustrating when wires lie across your desk and get in the way of papers or drop down and get crushed and tangled under chair wheels. If your work requires that you get up from your desk (whether on a call or not) you’ll need to unclip the headset or take it off each time & reclip/put it back on when you return. If you do this often, a wireless headset could save you time, hassle (and hair!). Corded headsets need connector cables, so don’t forget to factor in those costs when pricing up your headset. If you have a phone that is not turning up on the compatibility guide, please do give us a call or send us an email and our staff will gladly check for you. The Verdict The Jabra BIZ 2400ii Duo is an executive level headset which is one of the most adaptable on the market.
