Closer Examination

I have checked out keyboards designed with mobile device integration of some sort in mind. Some even add speakers, which in hindsight is a hilarious thing to imagine taking with you to Starbucks and plopping down on a table. With the K620T, Ajazz hit a middle ground as the design is flashy enough to fit their portfolio of color schemes well, but also just functional enough to support a tablet or phone (or both at once) with that cutout slot up top. The new K620T 2.0 uses the same design and goes with pastel colors throughout, with pink or blue for their switch options and a large wheel in the top-left corner taking up the additional available space. The actual keyboard section is small, and it is a 60% keyboard that has the alphanumeric section of a full-size keyboard only except for Esc instead of Tilde (~), which may irk some programmers.

There are no visible logos anywhere in use, but no one can call this a stealthy keyboard and get away with it. There are indicator LEDs here too, which is possible because of the larger-than-usual form factor for 60% keyboards, such as the CORSAIR K65 RGB MINI we only just saw. There seems to be a massive spike in popularity for 60% keyboards, and companies are rushing in more than ever before to take advantage of it. Bezels are average in size, and the keyboard is still on the lighter side, especially in terms of density because of the ABS plastic construction for the case and the smaller form factor. The keycaps predominantly have single legends, with the modifiers and number keys including traditional secondary legends. These secondary legends are placed above the primary ones, and all are biased towards the left. No layered functions get keycap legends here, which is an interesting move on a 60% keyboard that depends on layers.


Flipping the keyboard around, we see the Ajazz logo and certification information printed on the case rather than a sticker. There is also a QC sticker up top, and four pill-shaped rubber pads at the corners lift it up to prevent scratches to the case while adding friction against the resting surface to prevent the keyboard from sliding around. The rubber pads are also pink to match the keyboard and cable, which is a nice touch even though you will never see them in use. There are no keyboard feet here, which means users cannot change the elevation of the keyboard. However, two fixed feet up top permanently elevate the keyboard.


I/O is all on the left side of the keyboard, where we see a small button to toggle between three stages (USB/Off/Bluetooth). Above it is the USB Type-C port, and the provided cable fits in snugly in a manner that reminds me of some laptop chargers. We can also better see the lines cut into the case to visually separate the three elements (keyboard, volume wheel, and mobile device slot). The cable is shorter in length than average at 5', which is a weird decision. If shorter than usual to accommodate mobile devices in wired mode, 5' is still far too long. To connect to a desktop PC, why not just use the standard 6' anyway? Perhaps it is the uncommon L-shaped connector and the pink insulation that are to blame. You need a spare USB Type-A port on the client either way.


I don't have a tablet on hand, but you can see some stock photos of the older and newer K620T using tablets in landscape mode, in addition to my phone to give you a visual perspective of the usefulness of the slot in that application. The slot is long enough to simultaneously accommodate a typical phone in landscape mode and a ~8–10" tablet in portrait mode.


Looking at it from the side gives us a better look at the high profile case design. We also see that Ajazz has gone with the OEM keycap profile of five slanted rows and contoured keycaps instead of the usual six owing to the smaller form factor. The provided keycap puller works alright, but fitting it between the keycaps isn't that easy on this compact keyboard. As such, you will only increase the possibility of scratching the keycap sides. Ajazz should have really gone with a metal wire keycap puller instead, especially as it wouldn't have added much to the cost. The stock keycaps are made out of thick PBT plastic (average wall thickness 1.45 mm) with double-shot injected legends. These don't support backlighting very well, however, so the onboard lighting is going to be more for accentuation than showcasing the legends themselves. On the plus side, these keycaps will basically last forever, definitely until you decide to get something else eventually. The color scheme depends on which variant you chose, with the blue version having blue keycaps.


There are two switch options for the Ajazz K620T 2.0, which unfortunately are contingent on the chosen keyboard color. So you can only get the pink switches with the pink keyboard, for example, as was the case here. These are Ajazz switches that have FIRSTBLOOD marked on them, which is an Ajazz keyboard model from before, but its name is now being used for the switch (Ajazz Firstblood). The pink switches are linear and have a pink stem/slider inside a transparent top and white opaque housing. The larger keycaps use Cherry-style stabilizers that work fine in combination with the thick PBT keycaps. Not much wobble or rattle here, although these will still be louder than the costar-style stabilizers, especially if the the costar-style stabilizers are lubed well.
