Wireless Range – Free Range (Conversations, Not Chickens)

Whether you’re working from home or in the office, it’s nice to have the freedom to move around. Jabra Engage 55’s compact USB DECT adapter delivers a wireless range of up to 150m/490ft from your computer, and also makes it easy for you to move about with your laptop while you’re on a call.

DECT Wireless – Power. Range. Security.

DECT wireless is specifically designed for wireless communications, making it an ideal choice for call-intensive workers who need additional mobility. In fact, the DECT wireless range of Jabra Engage 55 is up to 15 times the average range of a Class 2 Bluetooth® device.

And if you’re working in a busy office, DECT wireless is built to withstand the density of large numbers of people working in the same place, so you’ll get a clear, robust, and secure connection for your conversations.

Secure DECT Wireless Adapter – Like Fort Knox. But Smaller

However, you’re working these days, if your conversations often include sensitive details, it’s important to know that the data is protected.

The ultra-secure wireless adapter for Jabra Engage 55 is DECT Security certified. But because your data security is so important to us, we go beyond the DECT Security Step C level with additional FIPS military-grade 256-bit encryption algorithms, to prevent eavesdropping and keep conversations secure.

Professional-Grade Conversations – This Sounds Serious

When you’re in back-to-back calls or virtual meetings, every word matters. Jabra Engage 55 features an impressive noise-canceling microphone that helps block out background noise to keep you sounding like a pro, whichever office you’re working from.

The speakers are optimized for speech clarity, while wideband audio delivers crisp, crystal clear, natural-sounding calls. So you can wave goodbye to crackly, robotic-sounding voices, and say hello to more engaging conversations.

Durable Adapter – As Flexible As Your Schedule

It’s designed to bend, reducing the risk of damage even if you leave it plugged into your laptop. Perfect for companies with clear desk policies, or workers who like a change of scenery.

Lightweight Comfort – Long-Day-Proof

An uncomfortable headset can really distract your focus from the conversation. That’s why we’ve made sure Jabra Engage 55 is lightweight, with a low clamping force, to avoid pressure and heat build-up.

So even when you’re in back-to-back calls all day, you can rely on your headset to help you keep your cool.

Sidetone – It’s Oh So Quiet

Nobody wants to be that guy shouting on all their calls. That’s why Jabra Engage 55 has adjustable Sidetone built in.

By playing a little of your voice into your speakers as you talk, Sidetone helps you to regulate your speech volume, reassuring you that your microphone is working, and combating conversation fatigue.

Hearing Safety – It’s What We Do

We’ve engineered Jabra Engage 55 with SafeTone™ 2.0, for superior built-in hearing protection.

What’s SafeTone 2.0 made up of?

  • IntelliTone™ 2.0 limits overall audio exposure
  • Speech Level Normalization and Intelligent Acoustic Shock Prevention maintain comfortable audio levels throughout the day

This advanced technology protects your hearing well-being, while also helping to prevent the virtual conversation fatigue that can result from poor audio.

Frequently Asked Questions:

How does Engage 55 differ from Engage 65 or 75? 

The Jabra Engage 55 features a new flexible, durable USB DECT adapter instead of a wireless base, making it even easier to move around with your computer during calls, and to switch between work environments.

How do I charge the headset? 

You can buy Engage 55 with or without a charging stand to suit your needs. If you buy the headset without a charging stand, it still comes with a charging cable that enables in-call charging for stereo and mono variants (not recommended for convertible models).

Can I connect the Engage 55 headset to my smartphone? 

No, Engage 55 only enables single connectivity to your PC or Mac. There is no Bluetooth connectivity. (If you require Bluetooth connectivity, we recommend the Engage 75 which allows connection to 2 Bluetooth devices at the same time).

Does it work with Mac and PC? 

Yes, it works with both systems.

How do I connect the USB adapter to the headset? 

The Link 400 adapter comes pre-paired with the Engage 55 headset

Does the microphone meet the Premium Microphone for Open Office standard and what does that mean? 

Yes, it does. This qualification is the strictest test requirement of how the headset microphone suppresses surrounding noise and office conversation from multiple directions. It is the ultimate reassurance that your headset will excel in an open office environment.

How long is the warranty period for Jabra Engage 55? 

The warranty period is one year for North America.

Can I adjust the speaker volume, answer, end and mute calls with Engage 55? 

Yes, simple controls on the headset enable you to easily control calls.

Is the battery replaceable? 

Yes, a replacement battery is available as an accessory for stereo and mono versions. The convertible version does not have a replaceable battery.

How is the 150 m / 490 ft range measured? 

The 150 m / 490 ft range is measured by “Line of sight” (LIS), which shows how far the headset can be from the adapter without affecting its ability to deliver clear conversations.

Range performance can be affected by different factors, including density issues. Dense building structure such as the number of thick walls between the adapter and the headset. How many people are sharing access to the same network (Connection density) can also affect your range performance.
