Jabra Engage 40 Stereo - Headset - on-ear - wired - USB-A - noise isolating - Optimised for UC — image 1

Sounds like satisfaction

With Engage 40, calls have more clarity, and customers enjoy an all-around better experience, thanks to our innovative Engage+ software. Make interactions more meaningful and effective, with real-time call insights.

This headset has been designed with you in mind (you’re welcome). It’s light, but sturdy. Comfortable, but sleek. Wear it all day, without feeling like you’re wearing it at all. With an intelligent microphone system that makes sound clearer than ever before, there’s no better headset to help you make every customer your most satisfied customer yet.

On the ball

A software system that can analyse conversations as they happen? Meet the Engage 40 with innovative Engage+ software, the future of contact centre headsets.

Live, on-screen pop-ups give instant feedback, so you can improve your customer’s call experience as it’s happening.

Engage+ delivers live guidance on factors affecting your customer’s call experience, including background noise, silence and interruptions. 1

Onboarding, coaching and retaining staff becomes a breeze, with meaningful data at your fingertips, giving insights that make your job easier and sweeter.

Double the mic, double the satisfaction

Sound quality can make or break a call. We equipped 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.

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.

A comfortable agent is a happy agent

An uncomfortable agent makes for an awkward call, so we've designed Engage 40 to be so comfortable that you’ll barely know it’s there. Weighing in at as little as 1.5oz, or 45g*, 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.

*weight varies for stereo and mono variants

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 centre headset can be tough. So we built 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 Engage 40 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.

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…)

With Engage 40’s specially engineered speakers, optimised 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.

Kind on the ears

That's the philosophy behind the revolutionary professional-grade hearing protection built into the Engage 40. 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 normalisation, 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.

Your new personal assistant

Imagine a helping hand to hear customers more clearly and to optimise 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*.

Crush the conversation

With Engage 40, all the power is at your fingertips. Answer, mute and control the volume of your calls with just a few simple taps. Handling calls has never been this simple.

The customisable buttons of the control unit can be integrated with your contact centre and Unified Communications (UC) platforms, including Amazon Connect and Genesys, for efficiency where it matters. Hop between platform screens and control the volume with programmable buttons for speedy call handling.

A better call experience for you and the customer has never been so easy.

Friends with everyone

Connecting with your customers is a walk in the park with Engage 40. The headset plays well with all leading contact centre and Unified Communications (UC) platforms and even has integrated call control for the likes of Amazon Connect, Genesys Cloud CX and NICE CXone, when used with the control unit accessory. 2

With a UC variant certified for Google Meet, Works With Chromebook3 and Zoom and another variant for Microsoft Teams, you can enjoy seamless and stress-free customer interactions across the board. Stay close. Stay in control. Stay connected.



2. Software may be needed for configuration. Refer to Jabra.com/platforms for details.

Come back later

Say ‘no’ to costly interruptions with the Engage 40 headset, which sets clear boundaries by showing when you’re busy.

A red light will glow automatically when you’re busy on a call, showing anyone around you that now isn’t a great time to chat - so you can stay focused on your customer and give colleagues a clear signal when you’re free.

I approached Kadron after a friend recommended him, having used him for their own business. I'm so glad I did! 😃 He is simply transforming my business and taking it exactly where it needs to be. He's incredibly patient with me and all of my ideas 😂, really listens to what I want, and somehow manages to bring it all together. I couldn't recommend him highly enough!
