The Logitech Signature Slim Keyboard K950 is a wireless keyboard designed for everyday browsing and productivity tasks. It has a full-size layout and low-profile design that makes it comfortable to type on without a wrist rest. It uses tactile scissor switches, supports multi-device pairing via Bluetooth, and is powered with two AAA batteries.
Our Verdict
The Logitech K950 is inadequate for competitive gaming due to its fairly high and inconsistent latency performance. That said, it's adequate for more casual gaming. It also has good overall build quality and a low-profile design that's comfortable to use without a wrist rest.
- Good overall build quality.
- Latency performance is adequate for casual gaming.
- Latency performance is too high and inconsistent for competitive gaming.
- Somewhat cheap feeling materials.
The Logitech K950 is a good office keyboard that connects wirelessly with an included USB receiver or via Bluetooth. It also supports multi-device pairing with up to three devices simultaneously. The tactile scissor switches produce a good overall typing experience that's also extremely quiet, and the low-profile design is comfortable to use without a wrist rest. The build quality is also good, but the materials feel somewhat cheap overall, particularly the keycaps. Unfortunately, the software customization is somewhat limited, and you can only re-assign and record simple macros to designated keys.

The Logitech K950 is generally good for mobile and tablet use. It has good overall build quality and is extremely quiet to type on. However, the overall material quality does feel somewhat cheap. The keyboard is also quite wide, so it's much better suited for a desktop setup and isn't designed specifically to be used on the go. It connects wirelessly with its included USB receiver or via Bluetooth with up to three devices, and it's fully compatible with major tablet and mobile operating systems. Lastly, it uses replaceable batteries for power, so you don't have to worry about charging cables.

The Logitech K950 is poorly suited for an entertainment or home theater PC setup. While it has good build quality and connects wirelessly via Bluetooth with up to three devices, its full-size form factor makes it a bit unwieldy to use from a couch. Unfortunately, it also lacks a set of dedicated media keys (although it's worth noting that the function row keys have default media key assignments out of the box). It also lacks backlighting, so you aren't able to read the legends in a darkened room.
- Good overall build quality.
- Supports Bluetooth connectivity and multi-device pairing.
- Full-size profile; isn't well-suited for portability.
- No backlighting.
- No dedicated media keys.
The Logitech K950 delivers adequate raw performance suitable for casual gaming. While it has a 1000Hz polling rate, both connectivity types are Bluetooth-based, so the effective polling rate is bottlenecked at a much lower rate of 143Hz. This keyboard also doesn't support NKRO, so some keys may not register if you press many keys simultaneously.
- Latency performance is adequate for casual gaming.
- Latency performance is too high and inconsistent for competitive gaming.
- Low effective polling rate.

Popular Keyboard Comparisons
The Logitech Signature Slim Keyboard K950 is a low-profile keyboard designed for productivity and everyday desktop use. Visually, it resembles the more premium Logitech MX Keys S but has a comparatively simplified feature set. The K950 lacks backlighting and has flat keycaps rather than dish-shaped keycaps found on the MX Keys S, which help ensure your fingers stay centered on keys while typing. This keyboard is powered by AAA batteries rather than being rechargeable via cable.
Overall, this is a versatile mid-range keyboard. It's a good option if you prefer a keyboard with replaceable batteries or own other peripherals in the Logitech ecosystem, particularly a Logitech mouse that uses the BOLT receiver. However, it offers a comparable experience to the less expensive Keychron B6 Pro and is noticeably less feature-rich and premium-feeling than the slightly more costly Logitech MX Keys S.

The Logitech MX Keys S and the Logitech Signature Slim Keyboard K950 are similar low-profile, wireless keyboards designed for productivity and everyday desktop use. The MX Keys S offers a more premium-feeling build quality and typing quality. Its keycaps, in particular, feel higher quality and have small dish-shaped tops that help better center your fingers while typing. It also has full white backlighting with shine-through keycaps. On the other hand, the Signature Slim Keyboard K950 has cheaper feeling materials and flat keycaps. It also lacks backlighting, and unlike the MX Keys, which recharges with a USB cable, the SIgnature K950 uses replaceable AAA batteries.
The Keychron B1/B6 Pro and the Logitech Signature Slim Keyboard K950 are low-profile wireless keyboards designed for productivity and everyday desktop use. The Keychron recharges with a USB cable, and while it doesn't feel as well built, it offers a slightly better typing experience and has dish-shaped keycaps that do a better job of keeping your fingers centered while typing. Its web-based software also provides significantly more in-depth customization options, including complex macros and the ability to reprogram any key. On the other hand, the Logitech feels a bit sturdier, but its software has limited customizability options, only allowing you to program simple macros or re-assign specific keys.
The Logitech Pebble Keys 2 K380s and the Logitech Signature Slim Keyboard K950 are wireless, low-profile keyboards with replaceable AAA batteries. The Pebble Keys 2 K380s is significantly smaller, with a compact (75%) layout, making it a much better option for mobile or tablet use on the go. It has a more cramped layout that may take some getting used to. Comparatively, the Signature Slim Keyboard K950 has a standard full-size layout with standard spacing, making it the more comfortable option for a desktop setup and for typing for longer periods.
The Logitech Signature Slim Keyboard K950 and the Microsoft Bluetooth Keyboard are low-profile wireless keyboards designed for general desktop use and productivity. The Microsoft keyboard has a slightly taller profile, so using a separate wrist rest is more comfortable. While both keyboards support Bluetooth, only the Logitech supports multi-device pairing. The Logitech also has a thinner profile and provides one extra incline angle with flip-out feet. Both keyboards offer limited software customization with the ability to record simple macros to specific keys.
Test Results
The Logitech K950 is a full-size keyboard, so it has a fairly large footprint on your desk. True to its name, it's very slim, but it's also quite wide, so it's still somewhat unwieldy to carry with you, and isn't specifically designed with portability in mind.
The Logitech K950 has good build quality. The exterior case is made of plastic with an aluminum plate inside. There's a bit of deck flex, but it doesn't feel flimsy. The keys and stabilizers are fairly stable without any noticeable wobble while typing. Rubberized feet on the underside do a good job of keeping the board in place. There's a compartment for storing the USB receiver when it's not in use.
Unfortunately, the keycaps are made of somewhat cheap-feeling ABS plastic which is more prone than PBT keycaps to having legends rub off after heavy use and can develop a shiny, slightly slippery texture.
Logitech advertises that the plastic of the Graphite colorway is made with 62% post-consumer recycled material, while the Off-white color is made of 48% post-consumer recycled material.
The Logitech K950 has a low profile, allowing you to type comfortably with your wrists sitting on your desk without needing a wrist rest. A set of plastic flip-out feet on the underside provides one incline option.
The hardware of this keyboard isn't designed to be customized.
This keyboard has no backlighting.
This is a wireless keyboard powered by replaceable batteries. It doesn't include a cable.
You can wirelessly connect this keyboard via Bluetooth or the included Logi BOLT receiver. Logitech advertises that this receiver uses modified Bluetooth technology, providing more reliable signal strength in congested wireless environments and a closed, end-to-end encrypted signal for better security. You can also use this BOLT receiver to pair newer Logitech peripherals, including the Logitech Signature M650
Logitech advertises a battery life of up to 36 months but doesn't provide specific details about how this estimate was produced, so your experience will vary depending on your usage.
The battery life LED in the top right corner turns red when the battery level drops below 5%.
Logitech claims there's sufficient battery life under 5% for up to a month of use, but again, your experience may vary depending on how often you use your keyboard.
You can program simplified macros, which Logitech calls Smart Actions onto select keys using Options+ software. For more details, see the Configuration Software section.
Above the Ins/Home/Page Up keys, there are three dedicated keys for switching between connected devices. Each of these keys has a small LED indicator in the top left corner of the keycap to indicate when that device is actively connected. There's also a power indicator LED in the top right corner of the keyboard.
By default, keys on the function row are hotkeys for media controls, screen brightness, and emojis, among other commands. This means that the F1-F12 inputs on the function row are secondary functions. To activate them, you need to hold down the FN key. The insert command is also secondary; its primary function changes between keyboard languages.
You can reverse this behavior by pressing Fn+Esc. Alternatively, you can toggle the Fn lock option using the configuration software. With the configuration software installed, you receive an onscreen notification when you turn on or off the Fn lock.
You can toggle between compatibility modes for different operating systems by pressing and holding the following hotkey combinations for three seconds:
- FN+O (MacOS)
- FN+P (Windows)
- FN+C (ChromeOS)
There's a full list of supported hotkeys, OS compatibility details, and other information in the included user documentation. You can see a digital version of this documentation on Logitech's website.
Overall, the Logitech K950 provides a good typing experience. The keys have standard spacing and feel stable, while the scissor switches offer satisfying tactile feedback and don't feel mushy.
Unfortunately, the ABS plastic keycaps feel somewhat cheap. The keycaps are also flat and don't have concave dish-shaped tops to help center your fingers and limit potential typos like the similar but more expensive Logitech MX Keys S.
This keyboard is extremely quiet and is very unlikely to bother anyone around you while you're typing.
This keyboard has moderate-weight scissor switches with a noticeable tactile bump to overcome before actuation. They have a fairly short pre-travel and total travel distance, providing a responsive-feeling typing experience.
The Logitech K950 provides reasonably good single-key latency performance that's adequate for everyday browsing, productivity tasks, and casual gaming. However, it's too high and inconsistent for competitive gaming.
This keyboard has satisfactory single-key latency performance. It's well-suited for everyday browsing, portability, and casual gaming. However, it isn't suitable for playing reaction-based or competitive games.
The Logitech K950 has a 1000Hz polling rate. However, its effective update rate is bottlenecked at 143Hz since it relies on the Bluetooth protocol for wireless connectivity, whether connected via standard Bluetooth or the included Logi BOLT USB receiver. This limitation isn't an issue when using this keyboard for everyday browsing or productivity, as high effective update rates are only important for gaming.
This keyboard also doesn't support NKRO, meaning some keys may not register if you simultaneously press many keys. Once more, it's very unlikely to present any issues when using this keyboard for everyday browsing or productivity unless you type exceptionally fast or frequently rely on long strings of hotkey commands.
This keyboard has poor chord split performance and isn't suitable for playing games that require many simultaneous inputs.
The configuration software has a simple layout. It allows you to customize key assignments on designated keys in the function row, the navigation cluster, and Numpad. However, you can't customize key assignments elsewhere on the keyboard.
You can also program what Logitech calls Smart Actions, which are simplified macros. There are also several premade Smart Action templates for various actions supporting multiple keystrokes, text input, and actions in multiple programs.
While you can't create true custom profiles using this software, you can configure profile settings for specific applications.
This keyboard is fully compatible with Windows, macOS, and Linux machines. However, select key functions like the emoji key or screen brightness hotkeys may not work or function differently, depending on the OS and comparability mode you're using.
On Windows, all functions work as expected in Windows compatibility mode.
On macOS with compatibility mode set to MacOS, the emoji hotkey doesn't work. The screen brightness and calculator hotkeys require you to install the Logitech Options+ software for them to work.
On Linux (Ubuntu 22), in Windows compatibility mode, the calculator, dictation, and emoji buttons do nothing, while the screenshot hotkey opens your home folder.
This keyboard is fully compatible with Android, iOS, and iPadOS devices. However, some default keys function differently, depending on what OS you're using and what compatibility mode you've set the keyboard to.
On Android, in Windows compatibility mode, the emoji and calculator hotkeys don't work.
On iOS, the emoji, calculator, and F3/F4 hotkeys do nothing.
On iPadOS set to Mac compatibility mode, the emoji, voice dictation (F5), calculator, and lock keys don't work.
