TL;DR: Same comfort, new texture, haptic vibes. Logitech’s MX Master 4 is a small evolution that keeps it at the top of the productivity pyramid.
Logitech MX Master 4
Some tech gear just sticks with you. Not because it’s perfect—nothing in this world of firmware updates and RGB-laden nonsense ever is—but because it becomes part of how you move through digital space. For me, that’s the Logitech MX Master line. I’ve written novels worth of emails, edited video timelines that refused to end, and played enough indie games with one of these mice to know: they’re the closest thing to a comfort object in the productivity world.

So when Logitech dropped the MX Master 4, I did what any long-time user would do—I sighed, said “fine, take my money again,” and waited to see if this was a bold new chapter or just another well-polished sequel. Spoiler: it’s mostly the latter, and that’s okay. Because sometimes what you want isn’t disruption; it’s reassurance. And the MX Master 4 is the tech equivalent of your favorite hoodie finally getting a fresh wash.
Familiar Feels, Slightly Different Weight
Pick it up and the first thing you’ll notice—well, if you’re obsessive like me—is that it’s a smidge heavier. 150 grams compared to the 141g of the MX Master 3S. Not a big deal, but you’ll feel it after a few marathon editing sessions. Still, the shape? Identical. It’s like Logitech photocopied the 3S and just added a few personality tweaks. That classic ergonomic hump still fits right into your palm like it was engineered for it (because it was). If you’re right-handed, it’s paradise. If you’re left-handed… I’m sorry, Logitech still pretends you don’t exist.

The dimensions—taller, wider, rounder—make it feel a little more premium than playful. It’s not a mouse that wants to go fast; it’s a mouse that wants to mean business. You don’t flick this thing—you command it. The MX Master has always been about authority, and version 4 keeps that energy alive.
Buzz Buzz, Baby
So let’s talk about the new party trick: haptic feedback. Yeah, the MX Master 4 now vibrates. Somewhere, a marketing team is popping champagne.
In practice, the haptics are surprisingly tasteful. It doesn’t feel like your mouse is trying to text you; it’s more like a subtle nudge when you perform an action. You can tweak it in Logitech’s Options+ software—dial it down, crank it up, or turn it off if you’re dead inside. It taps gently when you switch devices, vibrates when your battery is about to bail, and buzzes softly when you snap something perfectly into alignment in Photoshop.
Do you need this? Absolutely not. But like noise-canceling headphones or a mechanical keyboard, once you get used to it, you kinda miss it when it’s gone. It’s not about necessity—it’s about feedback that feels human, not just digital. It’s Logitech giving your productivity a heartbeat.

The catch? Barely any apps support it right now. Photoshop, Lightroom, Zoom—because of course Zoom—and Premiere soon. Logitech’s opening up the SDK, but who knows how many developers will care. Until then, the haptics live in this weird in-between space: cool tech, limited utility.
Goodbye Rubber, Hello Texture
Remember how the old MX Masters used to get that gross, tacky, peeling rubber after a year or two? Logitech finally fixed that. The MX Master 4 swaps most of the rubber for textured matte plastic. It’s cleaner, tougher, and way less sweaty. The thumb rest still keeps its grippy surface, but overall the feel is smoother, cooler, and—dare I say—more adult.
The change isn’t flashy, but it’s smart. The 3S aged like a banana peel under constant desk use; this one feels like it’ll survive the apocalypse. And the best part? No more awkwardly explaining why your $100+ mouse looks like it’s shedding.

That Scroll Wheel Still Slaps
Logitech didn’t mess with perfection. The MagSpeed scroll wheel is still the best in the game—metal, weighted, and capable of switching between ratchet and free-spin modes with a satisfying thunk. Whether you’re doomscrolling Twitter or scrolling through endless code, it’s a joy. There’s a tactile sensuality to it (yeah, I said it) that most tech companies could never pull off.
The side scroll wheel? Slightly smoother, slightly more responsive, still one of my favorite things about the MX Master line. If you live in spreadsheets, timelines, or design software, it’s a lifesaver. Logitech could’ve added RGB lighting and ruined it—but thankfully, they didn’t.

Little Fixes, Big Wins
The MX Master 4 is filled with micro improvements. USB-C receiver? Finally. Bigger PTFE feet? Glides like butter. Better button placement? My thumb thanks you. The gesture button has been freed from its weird hiding spot, and the translucent edge glow adds a subtle futuristic flair without feeling like a gamer gimmick.
Even the exposed screws on the bottom are a quiet statement: Logitech wants this thing to be recyclable. It’s a tiny design note that says, “Yeah, we thought about the planet for once.”

The Everyday Grind
Using the MX Master 4 daily feels like slipping into a rhythm. The clicks are whisper-soft—great for late-night editing sessions or shared workspaces. The Options+ software is still bloated but ridiculously customizable. You can map buttons per app, fine-tune scroll behavior, and even set gestures for launching apps or controlling windows. It’s geek heaven.
Battery life? Rock solid. Logitech claims 70 days, and I believe them. I’ve gone weeks without charging, and the battery meter barely moved. It connects to three devices at once, jumps between them instantly, and tracks flawlessly on glass. It’s like the Tesla of mice—overengineered but reliable.

Still, there are gripes. Logitech didn’t include a USB-C cable in the box. The polling rate is still 125Hz, which feels archaic for 2025. And yes, you still have to keep Options+ running for the haptics to work. It’s a masterpiece with a few smudges.
Final Thoughts: The Comfortable Future
The Logitech MX Master 4 is what happens when a company knows its audience and refuses to fix what isn’t broken. It’s not a revolution—it’s a refinement. A mouse that says, “I see you, power user, and I’ll buzz gently when you’re doing great.” The haptics are fun but not life-changing. The texture is better. The build is stronger. And the overall experience? Peak Logitech.
If you’ve got a 3 or 3S, you can wait. But if your old mouse is peeling, glitching, or just uninspiring, the MX Master 4 is ready to reclaim desk space and productivity glory. It’s the gold standard for the kind of person who reads keyboard firmware changelogs for fun.
