Microphone Quality — Double the mic, double the satisfaction

Sound quality can make or break a call. We equipped the Jabra Engage 40 with not one, but two microphones: One to help you defeat background noise once and for all, and the other to keep your voice razor-sharp, enabling accurate speech-to-text capability.

Jabra Engage USB Headset with Busylight

Combined with intuitive Engage+ software, our innovative microphone tech creates such harmonious conditions, that it can help reduce average call handling times across the board.

Comfort A comfortable agent is a happy agent

An uncomfortable agent makes for an awkward call, so we’ve designed the Jabra Engage 40 to be so comfortable that you’ll barely know it’s there. Weighing in at as little as 1.5oz, it’s super lightweight, with angled cushions for the most comfortable fit.

We’ve also popped an innovative maze-shaped pattern on the earcups of every headset. It’s based on studies of actual users like you, and designed specifically to relieve pressure on the ear, helping you stay relaxed, and focused on the needs of your customer.

Durability Built for “oops”

Carelessly removed at the end of a long day, passed from desk to desk, tossed in a bag – the life of a contact center headset can be tough. So we built the Engage 40 to be one tough cookie, stress testing everything from boom arm rotation to impact resistance, making it our strongest, and longest lasting headset yet.

It’s easy to make bold claims, but we’re so confident that the Jabra Engage 40 USB mono headset will stand the test of time, and the cruel conditions a headset suffers, we’ve added a three-year warranty for all headsets. Lightweight, ultra-comfortable, and built to last, this headset has it all.

Audio Quality — Easy listening

With advanced speakers and innovative noise-isolating earcups that fit perfectly, you’ll never miss an important detail during a call (or have to ask anyone to speak up, or repeat the same information 47 times…)

Jabra Soft/Comfortable Leatherette Ear Cushion

With Jabra Engage 40 USB mono headset’s specially engineered speakers, optimized for speech clarity, frustrations are eased, and calls are more productive. Bringing crystal clear sound quality to every call, BalancedVoice™ will also automatically ensure that incoming calls are crisp and clear – just another clever feature bringing calm efficiency to every conversation.

Hearing Protection — Kind on the ears

That’s the philosophy behind the revolutionary professional-grade hearing protection built into the Jabra Engage 40 USB Mono headset. With Jabra SafeTone™ 2.0, you can focus on your calls, safe in the knowledge that your hearing is protected.

We’ve included loads of groundbreaking hearing protecting technologies, including:

  • IntelliTone 2.0™, which keeps average noise exposure at a safe level
  • PeakStop™ 105 dB, which prevents sudden loud noises
  • BalancedVoice™, which processes the incoming sound for clearer calls
  • Speech level normalization, which keeps incoming calls at your preferred volume
  • Intelligent acoustic shock protection, which proactively removes or reduces potentially harmful sounds

Because hearing protection isn’t an afterthought. It’s a lifetime investment.

BalancedVoice™ — Your new personal assistant

Imagine a helping hand to hear customers more clearly, and to optimize the dynamics of every call, allowing you to enjoy more balance on a long-shift.

Engage 40 uses a unique signal processing algorithm, BalancedVoice™, to stop you constantly cranking up the call volume, and keep you call ready throughout the day. Relax, avoid call fatigue, and focus on your customer – it’s all taken care of.

But we would say that, so we tested this unique technology with users like you. They agreed that it makes higher-pitched voices clearer, and makes speech easier to pick out from background noise, all while cleverly evening out voice tone, creating harmony for your ears*.

Frequently asked questions.

What is a digital headset?

A true digital headset has the processing chip in the headset instead of in a control unit or cord. The Engage 50 II and Engage 40 use the very latest chipset to be able to deliver enhanced, real-time analytic features, and this, along with the positioning of the chip, delivers enhanced functionality and user experience.

What does a digital corded headset offer over a regular USB type headset??

Most likely, a regular USB type headset does not have the chip in the headset itself which limits the hardware and software experiences it can deliver.

What Jabra professional digital headsets offer software integration?

All Jabra USB headsets are supported in Jabra Direct and Xpress software and can be integrated by third-party platforms through our SDK.

However, the Engage 50 II and Engage 40 also offer additional advanced call analytic metrics such as boom arm position alerts (Engage 50 II), background noise tracking, cross-talk sensing and more. These are presented within our free Engage+ application and are also accessible through our SDK.

What does the Engage 40 control unit offer, and why would I want to use it?

Answer, mute, and control the volume of the calls with just a few simple taps. The customizable buttons of the control unit can be integrated with contact center and Unified Communications (UC) platforms, including Amazon Connect and Genesys, for efficiency where it matters.

The Engage 40 is also compatible with the Engage 50 II controller, or as a standalone headset.

Can I connect to a Mac, or is this headset only compatible with a PC?

Yes, it’s possible to connect to Mac.

How do you reprogram the busylight?

The busylight can be programmed to change pending on selected active events, such as whether the agent is in a call, needs support from a supervisor, busy with after-call work, or available to help a colleague. The settings are made through a Jabra SDK integration.

How do you re-program the control unit for speed dial or other functions?

Two numbers can be set-up for speed dial on the control unit. The buttons can be reconfigured in Jabra Direct or through an SDK integration.

How does Engage 50 II differ from Engage 40?

Engage 50 II offers an even better microphone performance with the advanced 3-microphone system to filter out background noise. Engage 50 II also has a SmartRinger built into the Engage 50 II Link controller which alert the user of an incoming call when the headset in lying on their desk. Engage 50 II offers enhanced comfort for all-day wearing with headband padding (stereo version only).

In terms of analytics, Engage 50 II can alert the user if the microphone is not positioned correctly (requires Jabra Direct, Engage+ or SDK integration).

What is the difference between the microphones in Engage 50 II and the Engage 40?

The Engage 50 II has one mic in the tip of the boom arm and two on the outer side plus advanced algorithms to create a beamforming pickup of the users’ voice and analyze noise coming from elsewhere, isolating the voice and removing the noise.

Engage 50 II can remove up to 36dB of noise due to the extra microphone and the enhanced capabilities this allows. This also enables the headset to sense when the microphone position is less than optimal and trigger a boom arm position alert through Jabra Engage+, Jabra Direct or with a third-party SDK implementation.

What is the difference between the microphones in Engage 50 II and the Engage 40? Continued

The Engage 40 has one mic in the tip of the boom arm and one on the outer side. In addition, advanced algorithms create a beamforming pickup of the users voice and analyze noise coming from elsewhere, isolating the voice and removing the noise. It does not have boom arm position sensing capability.

How do I get access to Engage+ software?

To download the free software application, please go to Jabra.com/Engageplus.

Do you need to be connected to the internet for Engage+ to work?

No, Engage+ does not require internet connection to work (except for downloading the application).

Do you collect any data from users of Engage+?

We only collect data about how the headset is used, operating system as well as software/application version. In Engage+ you can turn of data collection under settings. We collect no personal data.

Is it possible to deploy Engage+ to many users simultaneously?

Yes, an MSI file is available on Jabra.com that allows for mass deployment

Does Engage+ require usage of Jabra Direct and Xpress?

No, Engage+ works independently from Jabra Direct and Xpress.

What impact does Engage+ have on system’s performance?

Engage+ takes up minimal space from your computer. Hard disk space: 300 MB, Installer file: 102 MB. When processing, the application uses RAM: 40-100 MB (100 MB is the max and is used to send notifications to the user).

Which headsets are compatible with Engage+?

Jabra Engage 50 II and Engage 40 are compatible with Engage+.

Which operating systems is Engage+ compatible with?

Windows 10 and 11

Does Engage+ alert me, if my microphone is in a vertical position and far away from the mouth?

No, that is too extreme a position for the microphone to pick up your voice and give you an alert. Engage+ will alert you when the microphone is slightly out of place like by your nose or your chin.
