Features:

Professional Noise-Cancelling Microphone for Clearer Business Calls

The Jabra EVOLVE 40 MS Dual/Mono Headset uses a professional unidirectional electret condenser noise-cancelling microphone engineered to prioritize the speaker’s voice while reducing unwanted background sound. With a 100 Hz–10,000 Hz microphone frequency range and wideband microphone performance, it is well suited to virtual meetings, customer support, sales conversations, remote collaboration, and other voice-intensive work. This focused microphone design is particularly valuable in shared offices and other environments where surrounding conversations can interfere with communication.

Wideband Voice Audio for Natural, Intelligible Conversations

Clear speech is essential when important details are being discussed. The EVOLVE 40 MS delivers wideband speech audio from 150 Hz to 7,000 Hz, helping voices sound clear and natural during compatible calls and conferences. Combined with its noise-cancelling microphone, this gives professionals a communication-focused audio system designed for understanding conversations without repeatedly asking callers to repeat themselves.

28 mm Speakers with HiFi Audio for Calls, Music, and Multimedia

The headset is equipped with 28 mm speakers that extend beyond everyday voice communication. They provide 20 Hz–20,000 Hz HiFi music frequency response, allowing the EVOLVE 40 MS to serve as both a professional communications headset and an everyday listening solution for music, presentations, webinars, training videos, and other multimedia. Speaker specifications include 93.6 dB SPL sensitivity at 1 kHz, 32 Ω ±4.8 Ω impedance, 5 mW rated input, and 10 mW maximum input.

Passive Noise Cancellation Helps Reduce Workplace Distractions

The EVOLVE 40 MS uses its on-ear construction and cushioned earcups to provide passive noise isolation without requiring powered Active Noise Cancellation. This physical barrier helps reduce surrounding high-frequency office noise and makes it easier to concentrate on calls or individual work. The Dual/Stereo configuration provides coverage for both ears when greater isolation is preferred, while the Mono version maintains greater awareness of the surrounding workspace.

Integrated Busylight Helps Prevent Unwanted Interruptions

An integrated red Busylight provides coworkers with an immediate visual indication that the wearer is occupied. It can illuminate automatically during calls and can also be manually activated when uninterrupted concentration is needed. In shared offices, this simple feature can reduce unnecessary interruptions without requiring the user to repeatedly tell coworkers that they are busy.

Dual/Stereo and Mono Options for Different Working Styles

Rather than forcing every professional into the same wearing configuration, the Jabra EVOLVE 40 MS is available in Dual/Stereo and Mono versions. The Dual/Stereo configuration covers both ears, providing stereo music playback and greater passive isolation for users who want to concentrate on calls or multimedia. The Mono configuration leaves one ear uncovered, making it easier to communicate with nearby colleagues and remain aware of activity around the workstation while still using professional headset audio.

USB-A or USB-C Options for Modern Workstations

Different EVOLVE 40 MS SKUs are available with either USB-A or USB-C connectivity, allowing businesses and individual users to select the interface appropriate for their computer hardware. The wired connection provides consistent communication without wireless pairing procedures, Bluetooth interference, or battery-management requirements. USB support also enables integration with compatible computer-based communication applications and the headset's inline controller.

3.5 mm Connectivity Adds Device Flexibility

In addition to its computer-oriented USB connection through the controller, the headset incorporates a 3.5 mm connection for use with compatible devices. This expands the headset's usefulness beyond a single workstation and can allow connection to supported smartphones, tablets, laptops, and other equipment with the appropriate 3.5 mm audio interface. Device functionality can vary according to the hardware and application being used.

No Batteries, Charging, or Bluetooth Pairing Required

Because the EVOLVE 40 MS is a corded headset, there is no internal wireless battery that needs to be monitored and recharged between shifts. Users can connect the headset and begin working without checking remaining battery life or troubleshooting Bluetooth pairing. This makes it especially practical for fixed workstations, reception areas, contact centers, customer service departments, and professionals who prioritize consistent availability over wireless mobility.

Convenient Inline Controls Keep Essential Functions Within Reach

The supplied inline control unit provides convenient access to important communication functions directly from the workstation. Depending on the connected application, users can answer and end calls, adjust listening volume, mute the microphone, and manage compatible call functions without navigating through software controls every time. Large buttons and visual LED indicators further support quick operation during busy working sessions.

Microsoft-Optimized MS Configuration for Business Communications

The MS version of the Jabra EVOLVE 40 was developed around Microsoft's professional communications ecosystem. Depending on the specific generation and SKU, Jabra documentation references certification and integration with Skype for Business, Microsoft Lync, and later Microsoft Teams-oriented variants. This makes the headset particularly relevant for organizations using Microsoft-based communications while maintaining interoperability with supported UC environments.

Broad Unified Communications Compatibility

Beyond its Microsoft-focused configuration, the EVOLVE 40 family was designed for professional Unified Communications (UC) environments. Jabra documentation references compatibility or certification across platforms and ecosystems including Avaya, Cisco, Alcatel-Lucent, Aastra, and other major UC solutions, depending on product revision and configuration. This makes it easier for organizations to integrate the headset into established communications infrastructure.

Magnetic Microphone Boom Creates a Cleaner Listening Setup

The microphone does not have to remain extended when it is not needed. Jabra's magnetic boom-arm design allows the microphone to be secured neatly against the headset when the user switches from calls to music or other listening activities. This provides a cleaner profile and makes the EVOLVE 40 MS feel less like a dedicated call-center headset during general computer use.

Flexible Boom Positioning for Left- or Right-Side Wear

The microphone boom can be positioned for left- or right-side use, allowing wearers to configure the headset according to personal preference or workstation layout. The boom supports up to approximately 270 degrees of rotation, giving users flexibility in microphone positioning while helping prevent excessive rotation beyond the intended mechanical range.

Jabra SafeTone Helps Protect Hearing During Extended Use

For professionals who spend significant portions of the day wearing a headset, hearing protection is an important consideration. The EVOLVE 40 MS incorporates Jabra SafeTone hearing-protection technology, with Jabra documentation also referencing PeakStop and IntelliTone G616 technologies. PeakStop is designed to help suppress potentially harmful sudden sound peaks before they reach the user's ears, adding protection for prolonged professional headset use.

Soft Audio-Foam Ear Cushions for Extended Wearing Comfort

The headset uses soft audio-foam ear cushions covered in black leatherette, creating a comfortable contact surface around the ears while also contributing to passive sound isolation. This construction is intended for professional environments where users may need to wear a headset through multiple calls, meetings, or extended work sessions rather than for only a few minutes at a time.

Padded Adjustable Headband for a More Comfortable Fit

Comfort extends beyond the ear cushions. The EVOLVE 40 MS incorporates an adjustable headband with ultra-soft foam padding and a silicone covering, allowing users to modify the fit while distributing pressure more comfortably across the head. This is especially useful for professionals whose headset remains part of their workstation for much of the working day.

Lightweight Mono and Stereo Designs for Everyday Professional Use

Despite its professional feature set, the EVOLVE 40 MS remains relatively lightweight. Jabra's newer specifications list the Mono model at approximately 143 g and the Stereo/Dual model at approximately 171 g. The Mono configuration minimizes weight while keeping one ear available for environmental awareness, while the Stereo version adds a second earcup for two-ear listening and improved passive isolation.

Stereo Listening for Greater Focus and Multimedia Enjoyment

The Dual/Stereo model provides sound through both ears, making it particularly useful for professionals who frequently alternate between calls and multimedia. Stereo reproduction provides a more immersive experience for music, training materials, presentations, and video content while simultaneously increasing physical isolation from surrounding workplace distractions.

Mono Listening Keeps You Connected to Your Surroundings

The Mono version is designed for users who cannot completely disconnect from their immediate environment. By keeping one ear uncovered, employees can continue hearing coworkers, announcements, customers, or other important sounds while participating in calls. This configuration can be especially practical for reception desks, collaborative offices, service counters, and workplaces where face-to-face interaction continues alongside digital communication.

Jabra Direct Support for Headset Management

Compatibility with Jabra Direct gives businesses and individual users access to Jabra's desktop device-management ecosystem. Supported functions can include device configuration, firmware management, and integration features, depending on the connected hardware and software environment. This provides an additional level of management beyond the headset's physical controls.

Jabra Xpress Support for Business Deployment

The EVOLVE 40 MS also supports Jabra Xpress, making the headset more suitable for organizations deploying Jabra devices across multiple users or workstations. Centralized device-management capabilities can simplify enterprise headset administration and help IT teams maintain standardized device configurations across supported deployments.

Generous Cable Length for Practical Desk Setup

A wired headset still needs enough reach to remain comfortable at a workstation. The EVOLVE 40 configuration includes an approximately 120 cm headset cable together with an approximately 95 cm controller cable, providing practical flexibility for arranging the headset, computer, and inline controller around a desk. Users can keep the controller within reach while maintaining enough cable length for normal seated movement.

Plug-and-Play Design Simplifies Everyday Setup

The EVOLVE 40 MS is designed around straightforward USB plug-and-play operation with compatible computers and UC software. There is no wireless pairing procedure or battery setup to complete before basic use. For organizations deploying numerous workstations, this straightforward wired approach can also reduce the complexity associated with managing wireless peripherals.

LED Indicators Provide At-a-Glance Status Information

Visual LED indicators on the headset/controller complement the physical controls and Busylight functionality. Instead of relying entirely on information displayed on the computer screen, users can obtain visual status feedback directly from their communications hardware, supporting faster interaction during calls and busy working sessions.

Professional Audio Without Wireless Downtime

One of the EVOLVE 40 MS's practical advantages is consistency. Because it receives power through its wired connection and does not depend on a rechargeable wireless battery, users don't have to interrupt their workflow because the headset needs charging. For high-volume call environments where a headset may be needed throughout an entire shift, that simplicity can be a significant operational benefit.

Wide Operating Temperature Range for Professional Environments

Jabra specifies an operating temperature range of approximately -10°C to +50°C (14°F to 122°F). This broad range supports use across typical professional environments and adds to the headset's suitability for businesses seeking standardized communications equipment for varied workplace conditions.

Two-Year Warranty Adds Long-Term Purchase Confidence

The 2-year warranty provides additional assurance for buyers investing in a professional headset for regular workplace use. Combined with the wired design, established Jabra business-audio ecosystem, replaceable-use accessories where applicable, and professional communications focus, the warranty strengthens the EVOLVE 40 MS as a practical choice for individual professionals and larger business deployments.

One Headset for Calls, Meetings, Training, and Music

The combination of wideband speech, HiFi music audio, a noise-cancelling microphone, USB connectivity, 3.5 mm flexibility, call controls, and professional comfort means users don't necessarily need separate headsets for communication and everyday computer audio. The EVOLVE 40 MS can move from a morning conference call to customer conversations, online training, multimedia playback, and music without requiring a change of audio device.

Professional Wired Reliability for High-Volume Communication

The strongest overall selling point of the Jabra EVOLVE 40 MS Dual/Mono Headset is the combination of business-focused audio and dependable wired operation. It avoids battery limitations while providing the features professionals actually use throughout the workday: clear wideband calls, a noise-cancelling microphone, HiFi audio, passive noise isolation, an integrated Busylight, hearing protection, inline controls, comfortable materials, flexible connectivity, and a choice between Mono and Dual/Stereo configurations. For offices, remote professionals, sales teams, customer service departments, contact centers, and organizations that need reliable communication equipment, these features make the EVOLVE 40 MS a versatile professional workstation headset.
