The Logitech K780 is a full-size keyboard that can be used with a wide variety of devices. Although it's designed to work with smartphones and tablets, the keyboard is quite large and heavy, which makes it less travel-friendly. It uses typical scissor switches that require a fair amount of force to actuate; however, the overall typing experience still feels light and responsive. You can use it with its USB dongle or over Bluetooth, and its multi-device pairing feature lets you pair to three devices simultaneously so that you can switch easily between them. Unfortunately, it lacks backlighting and macro-programmable keys, and while its latency shouldn't affect general desktop use, it isn't ideal for gaming.

Our Verdict

6.1 Gaming

The Logitech K780 isn't intended for gaming. Although its scissor switches have a short pre-travel distance, they require a fair amount of force to actuate. Additionally, the latency is quite high. It also lacks backlighting and macro-programmable keys.

Pros
  • Great typing experience.
  • Short pre-travel distance.
Cons
  • Limited customization options.
  • No backlighting.
  • High latency.
  • No macro-programmable keys.
6.9 Mobile/Tablet

The Logitech K780 is an okay keyboard for mobile devices and tablets. Even though it's a bit large and slightly heavy, you should still be able to bring it around thanks to its slim profile. You can connect it to your device over Bluetooth and pair multiple devices simultaneously so that you can switch between them with just a press of a button. It provides a great typing experience and is compatible with most mobile operating systems.

Pros
  • Versatile design, works with every platform.
  • Can be paired to three devices simultaneously.
  • Great typing experience.
Cons
  • Limited customization options.
  • Not very travel-friendly.
7.9 Office

The Logitech K780 is good for office use. It provides a great typing experience and doesn't cause much typing noise, making it a good fit for quiet offices. You can connect it using its USB dongle or over Bluetooth, and its multi-device pairing feature lets you pair to multiple devices simultaneously so that you can switch easily between them.

Pros
  • Versatile design, works with every platform.
  • Great typing experience.
  • Quiet typing noise.
Cons
  • Limited customization options.
6.7 Programming

The Logitech K780 is an okay keyboard for programmers but isn't designed for this use. It can be useful to use on a tablet or phone to navigate a mobile version of your code, but we don't recommend it if you're programming on a desktop. It lacks backlighting, and you can't set any macros.

Pros
  • Versatile design, works with every platform.
  • Can be paired to three devices simultaneously.
  • Great typing experience.
Cons
  • Limited customization options.
  • No backlighting.
  • No macro-programmable keys.
5.5 Entertainment / HTPC

The Logitech K780 is inadequate for use with a home theater PC. Its Bluetooth connectivity means you can pair it to a wide range of devices and keep your living room free of cables. However, it lacks a trackpad, so you'll need a separate mouse to navigate. Also, it's hard to see the keys in the dark because there's no backlighting.

Pros
  • Versatile design, works with every platform.
  • Great typing experience.
Cons
  • Limited customization options.
  • No backlighting.
  • No trackpad.

Build Quality
Keycap Material ABS

The Logitech K780 has decent build quality. The frame is made from very solid plastic with very little flex. The tablet/phone stand feels durable and has a grippy texture so your devices stay in place well. However, the keycaps feel a bit light and cheap.

The Logitech K780 can be used wirelessly with its USB receiver or via Bluetooth. You can either pair it via USB and two more Bluetooth connections or with three Bluetooth devices at once, and you can easily switch between them with the F1-F3 keys. The keyboard comes with 2x AAA batteries, and the manufacturer rates the battery life at 24 months, but we don't test this.

This keyboard has a few hotkeys (F4-F6 and the search key) that you can reassign to other commands from a list of presets, but you can't really program any yourself. It can also automatically detect which kind of device you're connected to and adjusts the keys accordingly. This keyboard's main feature is that it has a nice stand for your mobile devices like a phone or a tablet. Out-of-the-box, The F keys default to media keys, but you can switch this in the software. You can also disable the Windows key in the software. If you'd like a keyboard with dedicated media keys, check out the Logitech K360.

This keyboard features typical tactile scissor switches. They have a very short pre-travel distance, which makes the keyboard feel very responsive. The bump before the actuation requires a fair amount of force to get over, but the overall feeling is still light and shouldn't cause fatigue.

Typing Experience
Typing Quality

The Logitech K780 provides a great typing experience. It might be weird at first for some due to the circular keys, but you get used to it quite quickly. The keys are very stable and their low profile is nice. The spacing of the keys is good and helps reduce typos. Since the bump of the keystroke needs quite a bit of force to get over, it's hard to accidentally press a key.

Very Quiet

Typing on this keyboard is very quiet and shouldn't bother others around you. The spacebar is slightly louder than the other keys, but it's still very quiet overall.

The latency is quite high. It's fine for general desktop use, but not for gaming. If you want a keyboard with lower latency for gaming, check out the Razer Huntsman V2 Analog.

Differences Between Sizes And Variants

The Logitech K780 comes in a speckled and non-speckled design, but we expect our review to be valid for both as the differences only seem to be aesthetic. We reviewed the non-speckled model.

Compared To Other Keyboards

The Logitech K780 is a very versatile keyboard. It's a decent keyboard overall but shines when you pair it to a desktop setup by using a tablet. You can easily switch between three devices connected and the scissor switches offer a nice overall typing experience, but won't satisfy gamers. For other options, check out our recommendations for the best keyboards for iPad, the best wireless keyboards, and the best keyboards for writers.

Logitech MX Keys

The Logitech MX Keys is a better keyboard than the Logitech K780 overall. It features backlighting, which is nice and is rechargeable instead of using batteries like the K780. Both use very similar switches, but the MX Keys' keycaps feel a bit better, and the keys are easier to actuate.

Logitech K380

The Logitech K380 is a better mobile keyboard than the Logitech K780 because its compact and lightweight design makes it easier to carry around. However, the K780 provides a better typing experience, and it might be a better choice for those who use the Numpad regularly.

Logitech K480 Bluetooth Multidevice Keyboard

The Logitech K480 Bluetooth Multidevice Keyboard and the Logitech K780 are both decent keyboards to use with mobile devices, but the K480 is easier to bring around. Its compact 65% design is easier to slip in a backpack than the full-sized K780. However, the K780 is better-built and features scissor switches that offer a much better overall typing quality than the K480's rubber dome switches.

Logitech K800

The Logitech K780 is a better overall wireless keyboard than the Logitech K800. It's fully compatible with macOS and offers a better typing quality than the K800. Some people might not like the circular keys of the K780, though, and might prefer the more typical design of the K800's keys. The K780 is also Bluetooth-enabled and can connect to three devices simultaneously and features a small cradle for your mobile devices as well.

Apple Magic Keyboard 2017

The Logitech K780 is a more versatile keyboard than the Apple Magic Keyboard 2017. All of the Logitech's keys work on all platforms, while the Apple is only partially compatible with Windows, and can't be used with Android devices. The Logitech can also be connected to three devices simultaneously via Bluetooth or its USB receiver, while the Apple can only be connected to one. On the other hand, the Apple is lighter and has a 60% compact design.

Logitech Craft

The Logitech Craft is a better wireless keyboard than the Logitech K780. The Craft has a white backlight, has a rechargeable battery, and has a detachable charging cable. On the other hand, the K780 is fully compatible with both Windows and macOS and is a bit quieter than the Craft.

Logitech K360

The Logitech K780 is a better wireless keyboard than the Logitech K360. The K780 feels much better-built, supports Bluetooth and multi-device pairing, and offers a quieter and more enjoyable typing experience. On the other hand, the K360 has dedicated media keys and may represent better value for some people.

Logitech K400 Plus

The Logitech K780 is overall a better keyboard than the Logitech K400 Plus. Unlike the K400, the K780 can pair with up to three devices at once via Bluetooth. The K780 also features a built-in stand for phones or tablets, making it the better choice for typing on a mobile device. On the other hand, the K400 Plus is better for a home theater setup thanks to its integrated trackpad and is designed to be used on your lap.

Microsoft Bluetooth Keyboard

The Logitech K780 is more versatile than the Microsoft Bluetooth Keyboard. It can be used with its USB receiver and via Bluetooth and its design offers a little cradle for your mobile devices, which is very useful. However, if you don't like circular keys, you might want to go with the Microsoft keyboard with its more typical square chiclet keys.

Lenovo ThinkPad TrackPoint Keyboard II

The Logitech K780 is a full-sized keyboard, while the Lenovo ThinkPad TrackPoint Keyboard II is a compact 75% board. Both are well-suited for use with mobile devices and tablets, but the Logitech has a cradle to hold your device in place. It can pair with up to three devices at once via Bluetooth and another via its USB receiver. Comparatively, the Lenovo has a TrackPoint to control the cursor and mouse click buttons at the bottom of the board. You can reprogram the F12 key to open a webpage, program, or file or insert a line of text. Both have tactile scissor switches, but the Logitech requires more force to get over the actuation bump. Unfortunately, neither board has backlighting.

iClever Tri-Folding Keyboard BK08

The iClever Tri-Folding Keyboard BK08 and the Logitech K780 are very different keyboards for mobile use. The iClever is a better keyboard if you're on the move often, while the Logitech is better if you want a separate work station at your desk with a mobile device or tablet. The iClever is more portable and practical if you move a lot and need to work in tight spaces like on the train, but the K780 is a more typical office keyboard with better build quality and an overall better typing experience.
