If you want a work-first headset built for calls, choose Jabra Evolve2; if you need headphones built for music and long listening sessions, choose MASTER & DYNAMIC MH40.
• Jabra Evolve2 — biggest strength: Active Noise Cancellation, a two-microphone call array and Microsoft Teams certification make it a purpose-built tool for meetings and UC platforms.
• Jabra Evolve2 — biggest trade-off: It is a mono, on-ear headband design in plastic with a single-ear focus, so it is less about immersive stereo music and more about being reachable on calls.
• MASTER & DYNAMIC MH40 — biggest strength: Custom 40mm titanium drivers, up to 30 hours of battery life and a premium aluminum, canvas and lambskin-leather build aimed squarely at sound quality and long wear.
• MASTER & DYNAMIC MH40 — biggest trade-off: There is no headphone jack and no active noise cancellation — isolation comes from the ear pads, not electronics.
• Who each pick is for: Jabra Evolve2 for the person who lives on Zoom and Google Meet; MASTER & DYNAMIC MH40 for the person who wants a beautifully made pair for music, commuting and hands-free calls.
The Evolve2 55 is a wireless headset that knows exactly what job it was hired to do. It connects to your laptop and your smartphone over Bluetooth 5.2, with a Link 380 Bluetooth adapter included in the box alongside a USB cable and a carry pouch. That adapter detail matters more than it sounds — it is the difference between "my headset works" and "my headset works in the meeting room, at the desk and on the train."
On the audio side, you get Active Noise Cancellation to push down the office hum, and two premium microphones to push your voice up. It is certified for Microsoft Teams and listed as working with UC platforms such as Zoom and Google Meet. If your calendar is a wall of back-to-back calls, that certification is the whole point: the mute, the answer, the hang-up — they behave the way the software expects.
Comfort is handled by what Jabra calls AirComfort technology, and the headset weighs just 2.72 ounces with a 30-metre Bluetooth range and touch-based media controls. The honest trade-off is the shape: this is a mono, on-ear headband unit in a plastic enclosure, and the frequency response tops out at 20,000 Hz with no stereo imaging story to tell. Who should buy it: remote and hybrid workers, support and sales teams, anyone whose headset is a work tool first. Who should skip it: listeners who want a wide, immersive stereo soundstage for albums, and anyone who dislikes on-ear pressure over long stretches.
The MH40 Gen II is the opposite philosophy. Where the Jabra optimizes for being understood, this one optimizes for what you hear. The headline change in this generation is a set of custom 40mm titanium drivers, tuned for deep, rich bass and clear treble across a 20Hz–20,000Hz range. That is a music-first tuning, and the materials back it up: anodized aluminum ear cups and controls, coated canvas, and lambskin-leather ear pads and headband.
Battery is the quiet superpower here — up to 30 hours, with 6 hours of listening from a 15-minute charge. That is the difference between charging every night and charging every few days. Bluetooth 5.2 with quick pairing covers up to 30 metres, and there is an optional USB-C to USB-C cord for wired digital audio up to 24-bit/96kHz if you want to go lossless from a laptop or a DAC-equipped source.
Noise control is passive, not electronic: the signature removable magnetic ear pads seal around your ears for isolation, and a dual microphone array with proprietary wind noise reduction handles calls. The design is 205mm x 202mm x 71mm, black metal with white leather, and there is no headphone jack on board — this is a wireless-first pair. Who should buy it: commuters, music lovers and anyone who wants one handsome pair to cover listening and occasional calls. Who should skip it: people who need active noise cancellation for a noisy open office, and anyone who still wants a 3.5mm cable in the bag.
• Best for work calls and UC platforms → Jabra Evolve2. Teams certification plus Zoom and Google Meet compatibility is a specific, practical advantage.
• Best for music quality → MASTER & DYNAMIC MH40. Custom titanium drivers and a 20Hz–20,000Hz range are aimed at listening, not just talking.
• Best for battery life → MASTER & DYNAMIC MH40. Up to 30 hours, and a 15-minute charge buys 6 hours.
• Best for blocking noise → Jabra Evolve2. Active Noise Cancellation does electronically what the MH40 does with ear pads alone.
• Best for all-day wear in long meetings → Jabra Evolve2. AirComfort technology and a 2.72-ounce build are designed around the marathon, not the album.
• Best for premium materials and looks → MASTER & DYNAMIC MH40. Aluminum, coated canvas and lambskin leather versus a plastic enclosure.
• Best for wired, high-resolution listening → MASTER & DYNAMIC MH40. Optional USB-C to USB-C supports up to 24-bit/96kHz.
• Best for people who want one pair for everything → it splits. Jabra for the job, MH40 for the life around it.
In my opinion, the MASTER & DYNAMIC MH40 is the one I would buy for myself. The custom titanium drivers, the 30-hour battery and the aluminum-and-leather build make it the pair I would actually reach for on a commute, on a flight and at my desk — and the dual microphone array with wind reduction means it still handles a call when one comes in. I would only steer you to the Jabra Evolve2 if your day is genuinely defined by UC meetings, because that is where its Teams certification, active noise cancellation and two-microphone clarity earn their keep. Buy the tool that matches the job you actually do. Check the current price on Amazon before you commit, since both sit in very different budget brackets.
FAQ
No. Its noise control is sound isolation from the removable magnetic ear pads, which seal around the ear. The Jabra Evolve2 is the one in this pair with Active Noise Cancellation built in.
The MH40 is rated at up to 30 hours of playtime, plus 6 hours from a 15-minute charge. Jabra does not list a battery figure for the Evolve2 55 in its specifications, so the MH40 is the clearer pick if battery endurance tops your list.
Yes, optionally — a USB-C to USB-C cord allows digital audio up to 24-bit/96kHz. Note there is no headphone jack, so it is USB-C digital audio rather than a 3.5mm analog connection. The Jabra Evolve2 connects via Bluetooth or its included USB cable and adapter.
