Anyone who spends eight hours or more a day using a keyboard and mouse will be familiar with the problem: towards the evening, your wrists get tired, your fingers become sluggish and your shoulders tense. Logitech addresses precisely this everyday problem with the recently introduced Logitech Signature Comfort Plus MK880 Combo. A wireless bundle of the K880 keyboard and M850L mouse that combines ergonomic design with modern multi-device connectivity and smart productivity features.

Logitech Signature Comfort Plus MK880 Combo Test: Design and workmanship

The most striking feature of the K880 keyboard is its curved shape. The keybed is not flat, but runs in a wave shape, which should guide the hands naturally outwards when typing. This comfort is underlined by the fixed, wide and soft palm rest, which also has an integrated wave pattern. Visually, the overall package looks tidy and modern. Just right for the professional desk.

Logitech has given the lower keys a kind of double assignment, which is why the K880 is intended for both Windows and Mac users. This makes it particularly easy to switch between different systems, even if it does have certain disadvantages: If you are a user of only one system, the keyboard no longer looks as tidy. If you work exclusively on Windows or macOS, the double labeling will be perceived as visual noise. System-specific variants would be desirable here.

The power switch is located on the upper side with a colored red-green background. On the underside, the keyboard has an integrated elevation with two different angles – 4° or 8° – which is really great. Many more keyboards should give the user a choice, as everyone favors slightly different ergonomics.

With the M850L, Logitech has tried something new with the palm padding: While many mice rely on a purely hard upper shell, the palm rest area is made of a soft and slightly flexible material. The mouse is covered all over with a non-slip rubber coating that has a fine, nubby texture. As a special extra for the feel and grip, Logitech has incorporated additional vertical stripes into the rubberized side walls. This is somewhat reminiscent of products such as the Logitech MX Master 4 (our test).

The workmanship is at a solid mid-range level. The mouse and keyboard are made of plastic and rubber, metal is not used. The combo can’t keep up with an MX Master, for example, but it doesn’t have to. However, both devices feel good, have a clean finish and are very comfortable thanks to the integrated cushions. Depending on the model and color, the set is made from 49 to 77 percent post-consumer recycled plastic, and the packaging is FSC-certified.

Features of the Logitech Signature Comfort Plus MK880 Combo

The MK880 Combo is packed with practical features. The K880 has numerous special keys in the top row of keys: From monitor lighting to smileys, microphone to music control and screenshots. The three buttons for the Easy-Switch function can also be found there to quickly switch back and forth between individual devices.

The keyboard and mouse support Windows, macOS, ChromeOS, Linux, Android and iPadOS. Users can connect up to three devices at the same time and switch between work laptop, private PC, tablet and smartphone using Easy-Switch. And without having to pair the peripherals each time.

Particularly interesting for the modern workflow: the keyboard has a customizable AI start button. Users can configure shortcuts to quickly launch AI tools such as OpenAI ChatGPT, Google Gemini or Microsoft Copilot – via Logitech’s Logi-Options+ software. The combo also supports Smart Actions automation, custom meeting controls, Zoom Workplace integration and Microsoft Teams controls.

The Logitech M850L mouse comes with a SmartWheel mouse wheel, an additional center button and two side buttons. On the underside, next to the battery compartment, are the power switch and the Easy-Switch toggle switch. A big minus: Logitech does not include a Logi-Bolt USB receiver in this bundle. If you want to take advantage of the Bolt receiver, you have to order it separately. This is absolutely incomprehensible to me.

Several years (!) of battery life

The battery life is one of the strongest arguments in favor of the MK880 Combo. As Logitech claims a battery life of up to 36 months for the keyboard and 24 months for the mouse, it feels like an eternity before replacement batteries are needed. You simply forget that you are working wirelessly and that’s a good thing.

Both devices rely on disposable batteries instead of integrated rechargeable batteries: the keyboard runs on two AAA cells, the mouse on one AA cell. If you prefer, you can also use rechargeable batteries. Absolutely powerful. So if you don’t feel like recharging regularly, you will benefit enormously. For office devices that are permanently on the desk anyway, the decision to use batteries is perfectly understandable. The multi-year battery life also reduces battery consumption and fits in with Logitech’s sustainability strategy.

App connection via Options+

The Logi Options+ software fully supports the Signature Comfort Plus Combo MK880. Although it is not a mandatory requirement for use, it allows the duo to be customized even more individually. As soon as you open Options+, both devices are displayed in a clear graphic and you have immediate access to all important parameters. All special keys on the keyboard can be customized.

The mouse also offers many customization options: whether classic copy-paste commands on the thumb buttons, individual mouse wheel settings or specific app profiles – Options+ is extremely powerful. The software automatically recognizes whether you are currently working in Photoshop, Excel or Teams and adjusts the assignment accordingly. Firmware updates can also be installed directly via the software.

Particularly practical in everyday multi-device use: Easy-Switch devices can be linked together in Options+. If you link a mouse and keyboard in the software, all you have to do is switch one device using a switch – the other one automatically follows suit. This worked without any problems in the test. The software also offers Logi Flow, which makes the interaction between different computers very uncomplicated. Simply move the mouse pointer over the edge of a laptop onto a desktop monitor and the keyboard follows automatically. This allows you to copy texts or files between two computers as if they were a single system. The personal profile is synchronized with a Logitech account. The settings are immediately available at every workstation.

Logitech Signature Comfort Plus MK880 Combo in a practical test

The first start is a breeze: pull the protective tabs out of the battery compartments, switch on the devices, pair them via Bluetooth and you’re done. Both devices are ready for use within a few seconds. No pre-installed software is required. If you want full control, install Logi Options+ afterwards.
The K880 takes a short time to get used to. Its curved shape forces you into a position that feels more relaxed after a few minutes than typing rigidly on a flat keyboard, even if it takes a little getting used to at first.

Anyone who has typed on a standard flat keyboard for years will consciously notice the waveform in the first few hours. After a day or two, however, typing with it will come naturally. The integrated cushion of the palm rest is soft, relatively insensitive and takes pressure off the joints. The keystrokes are cushioned and have a pleasant pressure point. Not completely silent, but with good haptic feedback. Especially in comparison to inexpensive office keyboards, the keystrokes feel much more premium.

The fold-out feet on the underside allow two different tilt angles: 4° and 8°. In everyday use, I worked almost exclusively at 8°. The stronger inclination relieves the wrists noticeably during long typing sessions without impairing control over the keys. Thanks to the numerous special keys, many helpful shortcuts are already available under Windows and macOS: calculator, lock screen, screenshot and more. All things that are regularly needed in everyday work and can now be done at the touch of a button.

With the Logitech M850L, I was curious to see if the palm cushion would make a difference and the answer is: it depends on the grip. The soft padding is a clever detail that has hardly been seen before. The mouse sits comfortably in the hand, but the cushion cannot reach its full potential in certain grip positions as it is barely touched. This may be different for other users. Those who use the mouse in a palm-grip position, where the entire palm rests on the mouse, will clearly benefit the most. For claw-grip users, the effect largely fizzles out.

What sets the mouse apart, regardless of the grip position, is the SmartWheel. It can best be described as the little brother of the MX Master’s MagSpeed mouse wheel. If you work precisely in documents, you get clean, line-by-line feedback. If you need speed, all it takes is a quick swing and the wheel automatically switches to freewheel. You can literally fly through long web pages without having to scroll your fingers to the bone. In everyday editorial work with long texts, tables and multi-page documents, the SmartWheel is the feature I would miss the most if it wasn’t there.

The quiet mouse click technology is also particularly useful for users in shared offices or open workspaces: even with quick click sequences, you can hardly hear anything. In combination with the muted keystroke of the keyboard, this creates a surprisingly quiet working environment. An aspect that you only appreciate when you have it.

The versatility was also impressive in the test: both devices could be easily paired with three different systems. Windows, macOS and iPadOS or Android. The connection is established after just a few seconds, and switching using the Easy-Switch button works flawlessly. If you use your work laptop during the day and your home desktop in the evening, you can switch at the touch of a button.

I would like to mention one point of criticism: the Logitech M850L is designed exclusively for right-handed users. Left-handers will have to look for an alternative. A pity for a bundle that otherwise appeals to so many user groups. And it’s a particular shame that Logitech is still not thinking along here. The MX Master series is also only available for right-handed users. Left-handers still have to make do with the outdated Logitech Lift (our test). And that’s annoying!

Logitech Signature Comfort Plus MK880 Combo Review: Conclusion

With the Logitech Signature Comfort Plus Combo MK880, Logitech has put together a fine package that closes the gap between standard office equipment and expensive high-end equipment impressively well. Anyone who sits at a computer all day long and whose wrists often give them a hard time in the evening will find a very good solution here. With a price of €109.99, the Combo MK880 is no bargain for the occasional user, but in the end it is not really overpriced for the performance it offers.

You get good ergonomics, the proven multi-device connection and a depth of software with Logi Options+ that is usually reserved for the more expensive models. If you are looking for a reliable, quiet and ergonomic input device bundle for daily office or home office use and don’t need a left-handed mouse, the MK880 Combo is a very good choice.
