The Logitech K400 Plus is a mediocre wireless keyboard with an integrated trackpad designed for PC-to-TV entertainment purposes. The all-plastic board shows quite a lot of flex and torsion, and its ABS keycaps feel slippery, but it feels light to type on. It isn't a good choice for programmers or gamers due to the lack of programmable keys and backlighting, but it's decent for office use as its typing noise is very quiet. Also, it has dedicated volume control keys and a built-in trackpad, great for smart TV use.

Our Verdict

6.2 Mixed usage

The Logitech K400 Plus isn't bad for mixed usage. Its low profile design makes it decent for the office and its typing quality is okay, but its lack of macro-programmable keys make it disappointing for gaming and programming. Also, it won't work with most mobile devices because it doesn't support Bluetooth connections. However, the keyboard is well-suited for a home theater thanks to its built-in trackpad.

Pros
  • Decent ergonomics.
  • Quiet typing noise.
  • Decent OS compatibility.
  • Built-in trackpad.
Cons
  • No Bluetooth support.
  • No macro-programmable keys.
  • No backlighting.
  • Poor software support.
5.9 Gaming

The Logitech K400 Plus isn't designed for gaming. Although it has a low pre-travel distance and it doesn't require much force to actuate each key, it has no macro-programmable keys or backlighting.

Pros
  • Decent ergonomics.
Cons
  • No macro-programmable keys.
  • No backlighting.
3.7 Mobile/Tablet

The Logitech K400 Plus doesn't support Bluetooth and isn't designed for use with mobile devices and tablets.

Pros
Cons
  • No Bluetooth support.
7.3 Office

The Logitech K400 Plus is a decent keyboard for the office. Its low profile design shouldn't cause much fatigue, but the small spacing between keys may cause a lot of typos. On the plus side, it's very quiet and shouldn't annoy those around you.

Pros
  • Decent ergonomics.
  • Quiet typing noise.
  • Decent OS compatibility.
Cons
  • Poor software support.
  • Compact and tight key layout.
  • No multi-device pairing.
5.2 Programming

The Logitech K400 Plus is inadequate for programming. Although it has decent ergonomics, it lacks backlighting and you can't program macros to any of the keys. On the upside, the build quality is decent, and it's compatible with macOS and Linux, although only partially.

Pros
  • Decent ergonomics.
Cons
  • No macro-programmable keys.
  • No backlighting.
  • 6.2 Mixed usage
  • 5.9 Gaming
  • 3.7 Mobile/Tablet
  • 7.3 Office
  • 5.2 Programming

This keyboard is similar in size to most TKL keyboards, but it includes a built-in trackpad like other entertainment keyboards. It's fairly light and is small enough to use on your lap when connected to a smart TV.

Build Quality

The build quality is decent. Its plastic frame gives a lot of flex and torsion, which isn't great, but it doesn't feel as though it's going to snap in half. The ABS keycaps feel pretty stable, although the spacebar rattles, plus the left and right trackpad buttons feel loose.

Note: While there are many reports of people having issues with the trackpad not scrolling well and registering double clicks, we don't currently test the trackpad as part of our test bench. That said, we didn't experience any issues with the trackpad while testing the Logitech K400 Plus. If you own it and have experienced issues, let us know in the discussions.

The ergonomics are decent. Although there aren't any incline settings or an included wrist rest, its low-profile design shouldn't cause much fatigue. The keys are quite close to each other, but your hand should still feel comfortable and not too cramped.

The Logitech K400 Plus has dedicated volume control keys, and it uses hotkeys for media control. There's also a left-click button on the top left so you can navigate the trackpad with your right thumb and click with your left. Although there's no Windows Key lock button on the keyboard, you can disable it in the Logitech Options software. However, you need to open the software each time you want to toggle the lock on or off since you can't remap any of the hotkeys to do it.

This keyboard also has an integrated trackpad. Some people have reported experiencing issues with it, but we didn't experience them during testing, though we don't test the trackpad as part of our test bench.

The Logitech K400 Plus keyboard uses rubber dome switches that feel like scissor switches and require a bit of force to actuate, though the overall feeling remains light. Due to the membrane switches, pressing a key can feel a bit mushy.

Typing Quality

The typing quality is okay. The ABS plastic keycaps feel slippery, and they also feel a bit mushy to type on due to the membrane switch. There isn't much space between each key, so the risk of typos is high since it might be hard to tell when your finger is in-between two keys. On the plus side, the keys feel pretty stable and the low profile design shouldn't cause much fatigue.

Very Quiet

The Logitech K400 Plus' typing noise is very quiet, so it shouldn't be bothersome in a noise-sensitive environment.

The Logitech K400 Plus has poor software support. The Logitech Options software allows you to remap some of the function keys, but you can only choose from a drop-down list of presets. You can disable the Window Key from the software, but you can only do it from within the software and you can't program any of the function keys to toggle the lock.

The keyboard has decent compatibility. All of its keys work on Windows, but some don't work on macOS or Linux. Some have a Windows-specific function that didn't translate to the correct action on macOS. However, all the alphanumerical keys should work fine.

Differences Between Sizes and Variants

The Logitech K400 Plus is available in both black and white, but the white model seems to only be available in some regions. Although we tested the black variant, we expect the white one to perform the same. You can see our unit's label here.

Compared to other keyboards

The Logitech K400 Plus serves its purpose as a wireless media keyboard with a trackpad, and it's designed to use on the couch while connected to a smart TV. It's very similar to the AmazonBasics K4R and the Corsair K83 Wireless Entertainment Keyboard, but it might provide better value for some users. Check out our recommendations for the best keyboards, the best wireless keyboards, and the best keyboards for writers.

Logitech K380

The Logitech K380 is a better keyboard than the Logitech K400 Plus. The K380's compact size is easier to travel with, and it can connect to any mobile device with Bluetooth support, unlike the K400 Plus. However, the K400 Plus does have a trackpad which makes it more ideal for a smart TV set up.

Logitech K480 Bluetooth Multidevice Keyboard

The Logitech K480 Bluetooth Multidevice Keyboard is better than the Logitech K400 Plus for mobile devices thanks to its Bluetooth support and its cradle for phones and tablets. However, the K400 Plus is better for office uses due to its better ergonomics and typing quality, and its better suited for home theater setups thanks to its built-in trackpad.

Logitech MX Keys

The Logitech MX Keys is a better keyboard than the Logitech K400 Plus. The MX Keys has a rechargeable battery and can pair with up to three devices at once via Bluetooth, unlike the K400 Plus that uses AA batteries and doesn't support Bluetooth. The MX Keys also has a built-in brightness sensor that will turn on backlighting to help you type even in darker rooms. However, the MX Keys has a numpad instead of a trackpad, so you would need to have an accompanying mouse if you wanted to use it with a home theater setup.

Logitech K780

The Logitech K780 is overall a better keyboard than the Logitech K400 Plus. Unlike the K400, the K780 can connect to a device via Bluetooth, and it can pair with up to three devices at once. 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.

Corsair K83 Wireless Entertainment Keyboard

The Corsair K83 Wireless Entertainment Keyboard is a better multimedia keyboard than the Logitech K400 Plus. The Corsair looks and feels better built, and, unlike the Logitech, it has backlighting and Bluetooth support. However, the Logitech might provide better value for some users since it's more budget-friendly.

iClever Tri-Folding Keyboard BK08

The iClever Tri-Folding Keyboard BK08 is better than the Logitech K400 Plus for mobile devices, thanks to its Bluetooth support and better portability. The Logitech isn't designed for mobile devices, but it has better ergonomics due to its slight incline and it has a companion software that allows you to make some customizations to the keyboard.

AmazonBasics K4R

The AmazonBasics K4R and the Logitech K400 Plus both have a built-in trackpad in place of a NumPad. They're very similar keyboards, but the Logitech requires less force to actuate a key and it has a second left-click button on the top left of the keyboard. Also, unlike the AmazonBasics, the Logitech has a companion software that allows you to make some customizations to the keyboard.
