Jabra BIZ 2400 II Duo - UNC

Jabra BIZ 2400 II Duo UNC 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). The headset comes in a Duo-headband only wearing style.  It has a noise cancelling microphone which rotates to allow it to be worn on either ear.

The 2400 II are the replacement range for the previous biz 2400 series. They are 40% lighter with improved design for superior fit and optimum positioning

This biz 2400 II comes with an Ultra Noise cancelling microphone ideal for even the noisiest of offices, so you can be sure the person you are talking to hears you only rather than what is happening around you.

All corded headsets come with a brand specific QD (quick disconnect) connection and require a same brand adapter cable to make them compatible with your phone or other device. These range in price from $15 upwards. Many of these cables look the same but are different inside, so if you’re not 100% sure which you need, give us a call and our staff will gladly check for you.

The Good

The Jabra BIZ 2400 II 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 2400 II Mono prevents any unwanted noise being heard by your callers, while the flexible boom ensures perfect positioning. This is a top level corded headset and has a unique 3 year manufacturer’s warranty for extra piece of mind.

The Not So Good

The downside to having flexibility in wearing style is the additional accessories and loss of durability. So if you are a little heavy handed or tend to misplace items.  This is a narrowband headset but is available in an IP (wideband version), the Jabra Biz 2400 IP

As with any corded headset, with the Jabra Biz 2400 II, 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 & amp; 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 & amp; reclip / put it back on when you return.  If you do this alot it can get super-annoying so a wireless headset could save you time, hassle (and hair!)If you don’t have a headset port on your phone, a corded headset will take the place of your handset. If you still want to use the handset you can pick up a switch to allow you to swap between the two.

As we’ve mentioned, 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 difficult to match for compatibility you may have to look at an amplifier. An amp, while providing superior call control (with mute and volume controls) and sound quality, will push up the price to about the same as a wireless headset (which  have an amp built in), no brainer – if you need an amp, get a wireless headset!

The Verdict

The Jabra BIZ 2400 II Duo UNC is an executive level headset which is one of the most adaptable on the market.

Other Headsets To Consider Before Buying

For users that are on calls for extended periods of time, or have a particularly noisy workplace the Jabra Biz 2400 Duo may be a better option to increase call concentration. If you like adaptable headsets, Sennheiser has some doozies; SH 335 and Sennheiser CS530 have 2 styles, the CC513 is a neckband style. If staff sit close together and it’s really noisy the ultra noise cancelling of the CC530 is definitely worth the extra investment.

Another factor to consider is the extra productivity that can be gained from the freedom to walk away from your desk while on a call. It is worth checking out the Jabra Pro 920 which is a great entry level wireless option for only a small amount extra. If the neckband is a big draw for you, the Jabra Pro 9470 and Plantronics Savi W740 both come with the neckband wearing style as well as headband and ear hook.

HD Voice/wideband audio
HD Voice lets you have lifelike, vibrant conversations. You will not have to struggle to hear what the other person is saying.

Kevlar reinforced cord
Cords are built to last and reinforced with Kevlar®. They are extremely durable and will take most daily punishments.

Multi device technology

Noise Cancelling microphone
Noise-cancelling microphone reduces unwanted background noise and is ideal in noisy open-office environments. Ultra noise-cancelling variant is also available.

Anti Shock Microphone
Having the mic close to your mouth can cause unwanted breathing noises. To reduce this, we have designed the mic with many small holes and placed a layer of foam on the inside. This prevents most air shocks and improves call quality.

Jabra BIZ 2400 II headsets are also available in wideband versions optimized for IP hardphones and softphones, and a USB stereo model for the ultimate IP/multimedia experience.
