The Keychron K2 (Version 2) is a decent entry-level mechanical keyboard. Its small and compact design makes it fairly easy to carry around, and you shouldn't have to worry about damaging it thanks to its excellent build quality. It's designed with macOS users in mind, but it comes with extra Windows keycaps as well. It works fully on both macOS and Windows, and only certain function keys don't work on mobile operating systems. It can connect with up to three devices at once via Bluetooth. Unfortunately, it doesn't have dedicated software, and you can't program any macros for gaming. Our unit has tactile Gateron Brown switches, and you can also get it with clicky Blue and linear Red switches. Unfortunately, the latency is a bit high, even when using a wired connection, which might disappoint serious gamers.
The Keychron K2 is good for gaming; however, the latency is a bit high, even over a wired connection. It should be fine for most casual gamers, but it might disappoint serious, competitive gamers. It has full RGB backlighting, but without dedicated software, you can't reprogram any keys.
The Keychron K2 is good for mobile use. It can be paired with up to three devices at once, and except for some function keys, it works properly on most common mobile operating systems. It's small, light, and it has an excellent build quality, so you shouldn't have to worry about damaging it during travel.
The Keychron K2 is good for office use. The unit we tested has Gateron Brown switches, which provide a great typing experience, and you can get it with other switch types if you prefer. It's well-built and has okay ergonomics with two incline settings, but it doesn't come with a wrist rest. It's also fully compatible with both macOS and Windows.
The Keychron K2 is good for programming. The keys are stable and the Gateron Brown switches on our unit provide a great typing experience. It's well-built with a solid aluminum frame and has two incline settings, but it doesn't come with a wrist rest. Sadly, it doesn't come with dedicated software, and you can't reprogram any keys.
The Keychron K2 is okay for use with a home theater PC. It has Bluetooth connectivity, so you can pair it to a wide variety of devices, and you can keep your setup wire-free. However, it doesn't have a trackpad for navigation.
We tested the Keychron K2 V2 with an aluminum frame, RGB backlighting, and Gateron Brown switches. It's available in a few different variants, including a hot-swappable version that allows you to quickly change the switches without soldering. The differences between the versions are listed below, and the build quality, typing experience, and typing noise may change depending on which model and switch type you get. It's the updated version of the Keychron K2 V1, which doesn't have an incline frame or a Caps Lock indicator light.
Keychron sells extra accessories for the K2 V2 mechanical keyboard. You can get a wrist rest and a set of PBT keycaps directly from their website, so your experience may vary with these extra parts.

The Keychron K2 is a decent, entry-level mechanical keyboard, and it's a better choice for mobile devices than the Keychron K4 or Keychron K8 because it's smaller and lighter to carry around. You can get it with a few different switch types, but sadly, you can't reprogram any of its keys, which is disappointing if you're a gamer. Also see our recommendations for the best keyboards for writers, the best mechanical keyboards, and the best keyboards for Mac.
The Keychron K3 and the Keychron K2 (Version 2) are two very similar keyboards, except the K3 has low profile switches while the K2 has normal-sized ones. The K3 has better ergonomics because its lower profile makes it comfortable to type on even without a wrist rest. It's also available in a wider range of switch types, including optical ones. However, the K2 offers better typing quality and feels better-built.
The Keychron K2 (Version 2) and the Keychron K8 are essentially the same keyboard in two different sizes. The K2 is 75%, while the K8 is 80%. The K2 is available with various Gateron switches, but the K8 has both Gateron and Keychron Optical switch options. That said, both keyboards have a hot-swappable variant that lets you change the switches without soldering. Latency is better on the K8, but the difference shouldn't be noticeable to most people.
The Keychron K2 (Version 2) and the Keychron Q1 are both 75% compact boards, but the Q1 is slightly larger due to its more spaced-out navigation keys and function row keys. You can use the K6 wirelessly via Bluetooth and pair it with up to three devices at once. Also, the K2 has more incline settings, and thanks to its Gateron Brown switches' transparent casing, white backlighting looks white, while the Gateron Phantom switches on our Q1 unit have a brown casing, making white lighting look red. On the other hand, the Q1 is hot-swappable, so you can swap out the switches with whatever you prefer, and it comes with customization software to set macros to any key. Also, while we bought the fully-assembled variant, the Q1 has a barebones version.
The Keychron K2 (Version 2) is a 75% version of the Keychron K4. The K2 that we tested has full RGB backlighting, while the K4 has white backlighting, although you can get it with RGB backlighting as well. The K2 is smaller and lighter, so it's a better choice for use with mobile devices. However, the K4 has more switch options because it's available with LK Optical or Gateron switches, whereas the K2 is only available with Gateron switches. The K2 has slightly higher latency, but it shouldn't be noticeable to most people.
The Keychron K2 (Version 2) and Keychron C1 are mechanical keyboards with similar looks but different sizes and connectivity options. The K2 is a compact (75%) keyboard that connects wirelessly via Bluetooth and can connect with up to three devices, while the C1 is a TenKeyLess wired keyboard. Unfortunately, both keyboards are fairly tall and don't include a wrist rest. That said, we tested each of these Keyboards with Gateron Brown switches that don't require much force to actuate and provide great typing quality with good tactile feedback. They're also both available with linear Gateron red and clicky Gateron Blues, and both have hot-swappable versions available as well.
The Keychron K Pro Series is the upgraded lineup of the Keychron K Series, which includes the Keychron K2 (Version 2). The K Pro Series features a better build quality that includes an aluminum frame option and PBT keycaps. The K Pro Series is also compatible with the VIA companion software so you can make adjustments to the keyboard, and it comes with a hot-swappable PCB and a layer of sound dampening foam to reduce typing noise, all of which are features that the K Series lacks. Otherwise, the K Pro Series and the K Series perform fairly similarly.
The Keychron K2 (Version 2) and the Keychron K12 are very similar wireless mechanical boards, but the K2 is a 75% board with a dedicated F-row and navigation keys, while the K12 is a 60% compact board. The K2 is available with white backlighting or RGB backlighting, and it's available with Gateron Red, Blue, or Brown switches. On the other hand, the K12 is available with the same K2 options, but it's also available with no backlighting at all, and it has more switch options, including Keychron mechanical and optical switches, as well as in a hot-swappable variant.
The Obinslab Anne Pro 2 is better than the Keychron K2 (Version 2) for most uses. The Obinslab has macro-programmable keys, customization software, and its latency is significantly lower, making it a much better choice for gaming. However, the Keychron has media controls and offers incline settings, which the Obinslab lacks. Both keyboards are available in a wide variety of mechanical switches.
The Keychron V Series are better keyboards than the Keychron K Series, which includes the Keychron 2 (Version 2). The V Series keyboards have a better build quality and a larger range of customization as they have a hot-swappable PCB and come with an included toolkit. The V Series boards are also compatible with the VIA companion software so you can make changes to the keyboard's lighting and key mapping whereas the K Series boards lack companion software. On the other hand, the K Series boards are wireless and use Bluetooth to connect with up to three devices at once whereas the V Series boards are wired-only.
The Keychron K7 and the Keychron K2 (Version 2) are compact office keyboards with similar features. The K7 is a 65% board available with Gateron Low Profile switches and Keychron Low Profile Optical switches. Since it has fewer keys, it lacks the dedicated function row and right Control key that the K2 has. On the other hand, the K2 is a 75% compact board available with standard-sized Gateron switches only. Both boards have a hot-swappable variant so that you can use whatever switches you prefer without having to solder them in yourself.
The Keychron K2 (Version 2) and the Keychron K10 are similar keyboards in terms of features, but they're available in different sizes. The K10 is full-size with a standard layout, while the K2 is smaller at a 75% size, so it doesn't have a numpad or certain navigation buttons like Print Screen, Scroll Lock, and Pause Break. The K2 feels better built because the frame doesn't flex as much, but that's likely because the K10 is larger. They have many of the same features, and they're available with the same switch options.
The Keychron K2 (Version 2) and the Keychron K14 are very similar wireless mechanical keyboards, but they're different sizes. The Keychron K2 is a compact 75% keyboard available in Gateron Brown, Blue, or Red switches. It also has a row of 10 function keys which the Keychron K14 lacks. On the other hand, the Keychron K14 is a Compact 70% keyboard available in either Brown, Blue, or Red Gateron G Pro or Keychron Mechanical switches. The K14 also has a hot-swappable version available, while the K2 does not.
The Keychron C2 and the Keychron K2 (Version 2) are very similar mechanical keyboards suitable for a variety of uses. The C2 is a wired-only, full-sized keyboard, while the K2 is a wireless, compact 75% keyboard. The two of them come with Gateron Red, Blue, or Brown switches, but both have hot-swappable versions if you'd prefer using other switch types. Both models also lack companion software, so you can't change keymaps without third-party software.
The Keychron K2 (Version 2) and the Keychron K3 (Version 2) are compact wireless keyboards that perform similarly. The major difference is that the K3 V2 is a low-profile board with low-profile switches with a much shorter pre-travel distance than the switches on the K2 V2. That said, the K3 V2 has better ergonomics because of its low profile, but the K2 V2 feels more like a traditional mechanical keyboard. Both keyboards come in hot-swappable variants, so you can swap the switches out without soldering.
The ROYAL KLUDGE RK61 and the Keychron K2 (Version 2) are both compact, wireless keyboards emphasizing mobile use. The Keychron is slightly bigger because it has a function row, navigation buttons, and dedicated arrow keys, but that means the ROYAL KLUDGE is smaller to carry around. The Keychron has RGB backlighting, and while the version of the ROYAL KLUDGE that we tested has blue backlighting, there's an RGB variant. Typing feels better on the Keychron because the keys are more stable, but since you can get each keyboard in a variety of switches, the typing quality depends on the ones you get.
The Keychron K2 (Version 2) is a compact (75%) keyboard that connects wirelessly via Bluetooth and can pair with up to three devices simultaneously. It also has a hot-swappable version available. On the other hand, the Keychron K6 is a full-size wired keyboard available either in a pre-assembled or barebones form. Overall, it has better build quality, higher quality keycaps, and customization software, which the K2 (Version 2) lacks.
The Keychron K2 (Version 2) is a compact (75%) wireless keyboard that's fairly customizable as you can a variant with a hot-swappable printed circuit board (PCB). The Keychron Q8, on the other hand, is a wired-only, Alice layout keyboard. The Alice layout means the keys are split into two distinct clusters that are angled away from each other to promote a more natural wrist placement. That said, the Q8 takes a bit longer to get used to at first, while you'll have no problem using the K2 V2 right out of the box.
The Keychron K2 (Version 2) and the Keychron K1 are both compact wireless keyboards, but the K1 uses low-profile switches, whereas the K2 uses standard switches. Also, the K1 is slightly longer since it has a TKL layout instead of a compact 75% like the K2. The tactile Gateron Brown switches on our K2 unit offer a better typing experience than the linear Gateron Low Profile Red switches on our K1 unit. While K2's wired latency is marginally worst than the K1, its Bluetooth latency is significantly better. Neither come with customization software.
The Razer BlackWidow V3 Mini HyperSpeed and the Keychron K2 (Version 2) are both wireless mechanical keyboards, but they're for different uses. The Razer is a better choice for gaming thanks to its incredibly low latency, macro-programmable keys, and customization software. Also, unlike the Keychron, the Razer has a USB receiver. On the other hand, the Keychron is a better option for office use, thanks to its full compatibility with Windows, macOS, and Linux. Also, the Keychron doesn't have the same quality control issues as our Razer unit does, so its typing quality is better.
The Vortex Race 3 and the Keychron K2 (Version 2) are both 75% keyboards with a similar layout, but the Vortex is wired-only while the Keychron is wireless with Bluetooth connectivity. The Keychron is more versatile because you can use it with mobile devices and pair it to multiple devices at once. If you're planning on using it for gaming, though, the Vortex is better because it has lower latency and macro-programmable keys. Also, it has onboard memory to save custom profiles. Both keyboards are available in various switch options, and the Vortex has a variant with backlighting.
The Keychron K2 (Version 2) and the Logitech POP Keys are compact wireless mechanical boards. Both have a dedicated F-row and arrow keys, but the Keychron has the traditional home cluster keys while the Logitech has dedicated emoji keys. The Keychron has a more standard rectangular key shape, which some people might prefer. It has incline settings and RGB backlighting. On the other hand, the Logitech has round keys which can cause more typos if you aren't used to them.
The build quality is excellent. The aluminum frame feels very sturdy and doesn't flex at all. The keys wobble a bit, but they don't rattle. The doubleshot ABS keycaps are just okay and feel like the weakest part of the build. That said, you can buy extra PBT keycaps from Keychron's website, or you can check out the Keychron Q2, which has PBT keycaps included in the fully-assembled variant. The feet feel sturdy and shouldn't collapse when you push the keyboard.
The Keychron K2 Version 2 has okay ergonomics. It has a fairly high profile, so some people might need a wrist rest to avoid getting wrist fatigue. Its frame is slightly inclined, which is one of the upgrades from the first version of the K2. Unfortunately, it doesn't come with one, but you can buy a wooden one from Keychron's website. There's also a low-profile version of this board, the Keychron K3 (Version 2), that has better ergonomics.
The Keychron K2 has full RGB backlighting with individually-lit keys. You can cycle through brightness settings and lighting effects using the Fn and function keys. It doesn't get bright enough to make the colors stand out in a well-lit room.
It comes with a detachable USB-C cable, and the keyboard connector has a 90-degree angle, so you don't bend the wire when it's plugged in. The cable is braided and retains kinks from the packaging.
The Keychron K2 can connect with up to three devices at once via Bluetooth, or you can use it wired while charging. The battery is advertised to last up to 240 hours with the backlight turned off.
The Keychron K2 doesn't have many extra features. There are media hotkeys, but you can't reprogram any buttons. Keychron recommends using third-party software to remap the keys. There are switches on the left side to use it in the Windows/Android or the mac/iOS modes and to use it wirelessly or wired. If having dedicated emoji keys is something you would enjoy, check out the Logitech POP Keys. For a more customizable and hot-swappable wired board, check out the Keychron Q1.
The unit we tested has tactile Gateron Brown switches, but it's also available with clicky Gateron Blue and linear Red switches. It's similar to the Gateron Brown switches on the Keychron K6 and Keychron K8. They don't require a lot of force to actuate, and they provide good tactile feedback. If you prefer something with low profile switches, then look into the Keychron K3.
The Gateron Brown switches on our unit provide a great typing experience. They offer good tactile feedback, and it's also available with Gateron Red and Blue switches, so you can get the ones you prefer. The keys are stable, but the spacebar wobbles just a bit. The compact 75% size may take some time to get used to, especially if you use non-alphanumeric keys, such as Page Up and Page Down, which are positioned differently than on standard full-sized keyboards. The right Shift key is smaller than the left Shift, so that may cause an increase in typos when you first use it. The function row is the same height as the number row instead of being slightly taller like on most keyboards, so it may feel different for some, but it shouldn't be too much of an issue. The ABS keycaps feel slippery, but you can get an extra set of PBT keycaps. The keys are light to press, and despite having a high profile, it shouldn't be too tiring typing on them for long periods. If you notice some fatigue, you can also get a wrist rest separately.
Our unit with Gateron Brown switches is quiet and shouldn't bother those around you. However, we expect the Gateron Blue switches to be louder, similar to the Cherry MX Blue switches on the Ducky One 2 SF.
The Keychron K2 has decent latency. It's better to use the wired connection for gaming, but even then, it might still be too high for competitive gamers.
Keychron K2 doesn't come with dedicated software to customize the RGB lighting or reprogram keys. However, Keychron recommends using third-party software to remap keys. In the manual, they recommend Karabiner for macOS and SharpKeys for Windows, but we don't test for these programs.
The Keychron K2 is fully compatible with both Windows and macOS, as long as you set the keyboard to the proper mode with the switch on the left side. The F3 and F4 keys don't work on iOS or iPadOS. You should set the OS slider to 'mac/iOS' if you're using it with Linux, but the display brightness up/down keys don't work. If you set the keyboard to the 'Windows' mode on Linux, all of the function keys, as well as the display brightness up/down, don't work.
