Logitech MX Brio Review: Great for Calls, Not for Creators
Logitech's 4K webcam is excellent at making you look professional on calls, and it quietly removed a feature its predecessor had.
Logitech’s MX Brio is the most expensive webcam the company makes for people who are not broadcasting for a living, and it arrived with one decision that will decide the whole purchase for a certain kind of buyer: it dropped a feature its predecessor had.
This is a research-based buying guide, not a hands-on test. It is built from Logitech’s published specification and from independent reviews by people with measurement setups, with sources at the end. Read our review standards.
The short answer
Buy it if you spend your working day on video calls and want to look professionally lit without setting up studio lighting. That is what it is genuinely excellent at, and the built-in microphones are unusually good for a webcam.
Do not buy it if you stream or make video content. Reviewers with test rigs consistently report the image is flatter and less detailed than other 4K webcams, because the AI processing smooths fine detail while it evens out the lighting.
The thing to know before anything else
The MX Brio is not compatible with Windows Hello. The Brio 4K it replaces was. If you log into your PC with your face, this is a downgrade, not an upgrade, and no amount of sensor improvement compensates for it.
The technical reason is straightforward. Windows Hello needs an infrared depth sensor, and the Sony Starvis sensor Logitech moved to does not include one. It was a deliberate trade: better image sensor, no IR channel.

Where the image quality actually lands
Logitech’s claim is twice the detail of the Brio 4K, from the larger sensor plus AI face-based enhancement. Independent testing broadly supports the comparison against its own predecessor — and also finds that it does not put the MX Brio at the front of the 4K field.
The pattern reviewers describe is consistent and worth understanding, because it is a design choice rather than a fault:
Good light — its home ground
Bright, evenly exposed, accurate colour, no blown highlights. This is the scenario it is tuned for, and it handles it without you touching a setting. Some reviewers note the result looks slightly undersaturated and a little flat — the even lighting comes at the cost of contrast.
Low light — about average
It lights you acceptably and largely gives up on the background, which ends up dim and poorly colour-balanced. Its own predecessor did a better job of lighting the whole scene, even if the subject was worse.
Backlit — where HDR earns its place
With a window or lamp behind you, HDR on keeps the background under control. Turn HDR off and the camera exposes for you properly but blows the background out. Neither is perfect; HDR on is the better default.
The microphones are the underrated part
Webcam microphones are usually an afterthought. These are not. The dual beamforming array suppresses steady background noise — computer fans, air conditioning — well enough that testers describe voices as crisp and reasonably full, and better than a pair of wireless earbuds.
They are still not a dedicated USB microphone or a desk condenser, and sitting a metre away from any microphone introduces room echo. But if the alternative is your laptop’s built-in mic, this is a real upgrade you get for free.
Build, mounting and the small details
The aluminium chassis is the obvious upgrade over the plastic Brio 500 and 300. It is also more than twice the weight of the old Brio 4K — 137 g against 63 g — which is why the included clamp uses a micro-suction pad to stay put on thin laptop lids.
The privacy shutter is the best thing about the physical design. It is a ring around the lens that twists closed, so it moves smoothly without knocking the camera out of position. Every webcam should work this way.
There is no lens cap in the box, which is a small irritation for a large glass lens that will collect dust and travel in a bag.
Show Mode
Tilt the camera down past horizontal and the image flips so you can show whatever is on your desk. It works, and it is genuinely useful for teaching or demonstrating something physical. Two caveats: the tilt takes enough force to disturb your careful positioning, and text on paper is too soft to read when zoomed. If desk-shooting is a regular part of your job, a gimbal-mounted camera does it better.
Strengths and compromises
What it does well
- Bright, even, professional-looking exposure straight out of the box
- Excellent integrated privacy shutter that does not shift the camera
- Dual beamforming microphones that are genuinely usable
- Solid aluminium build with a tripod thread as well as the clamp
- Works with three different Logitech apps rather than forcing one
- HDR that meaningfully helps in backlit rooms
What to think about first
- No Windows Hello, unlike the model it replaces
- Flatter, less detailed image than rival 4K webcams
- Most video platforms cap you at 1080p anyway
- Low-light background rendering is weak
- Heavy enough to need the adhesive pad on thin screens
- No lens cap included
- Flagship money for capability most callers will not use
The 4K question nobody asks out loud
Zoom, Teams, Google Meet and most streaming platforms cap your outgoing video at 1080p. In everyday use, a 4K webcam is sending 1080p.
That does not make 4K pointless. A larger sensor gathers more light, and the extra pixels give you room to crop or use the digital zoom without turning to mush. But if your reason for buying is “4K will look sharper on calls,” it will not, and a good 1080p camera will serve you just as well for considerably less.
Who should buy it
Good fit
- Remote workers on calls most of the day
- Anyone in a room with mixed or awkward lighting
- People who want one device instead of a camera plus a microphone
- Anyone who wants a physical shutter they trust
Look elsewhere
- You log in with Windows Hello
- You stream or shoot product video
- You move around while presenting — a tracking camera suits you better
- You want the best image per pound, not the best image for meetings
What we could not assess
We have not photographed a test scene under controlled lighting, measured colour accuracy, or run it through a month of calls. The image-quality descriptions above are drawn from reviewers who did, and we have said where they disagree with Logitech’s own marketing.
Long-term reliability is the other unknown. The MX Brio has been on sale since March 2024, which is long enough for widespread faults to surface, and none have.
Frequently asked questions
Does the Logitech MX Brio work with Windows Hello?
No. Neither the MX Brio nor the MX Brio 705 for Business supports Windows Hello facial login. The older Brio 4K did. The Starvis sensor Logitech moved to has no infrared depth channel, which is what Hello requires.
Is a 4K webcam worth it for Zoom and Teams?
Not for the resolution itself — those platforms cap outgoing video at 1080p. It is worth it for the larger sensor, which handles difficult light better, and for the ability to crop or zoom without losing quality.
Does it need a USB-C port?
It ships with a USB-C to USB-C cable, but it will work over USB-A with an adapter or a USB-C to USB-A cable, as long as the port is USB 3.0. USB 2.0 will not carry the bandwidth.
Are the built-in microphones good enough to skip a headset?
For internal calls, usually yes — the dual beamforming array handles steady background noise well. For anything recorded or client-facing, a dedicated microphone still sounds noticeably better, because no microphone a metre from your face escapes room echo.
MX Brio or Brio 300?
The Brio 300 is 1080p, plastic, far cheaper, and produces a similar exposure profile because it uses the same tuning philosophy. If budget matters more than sensor size and build, the gap is smaller than the price difference suggests.
Can it be mounted on a tripod?
Yes. There is a standard 1/4-inch thread on the base, and the monitor clamp attaches magnetically so it comes off without tools.
- Blue Yeti USB microphone — if call audio matters more than video
- Rode NT-USB Mini — the smaller desk condenser
- Jabra Evolve2 75 — headset route instead
- Anker 7-in-1 USB-C hub — if you are short on ports
- Elgato Stream Deck MK.2 — mute and camera toggles on hardware keys
