Comparison Aula WIN60HE Max vs Aula WIN68HE

Legend application indicates how the Latin characters on the keys are made and how well they will survive years of heavy typing.

— Double-shot. The keycap is molded from two different plastics: the main “body” and a separate legend insert are formed together in a single mold, so the letters don’t wear off or fade at all. This method is ideal for RGB backlighting: if the legend layer is semi-transparent, light passes through the symbols without halos. ABS double-shot is more common (bright glow, pleasantly smooth feel), while the pricier PBT double-shot is rarer and offers higher surface wear resistance. Compared to laser engraving, the lifespan is an order of magnitude higher, and it beats the dye-sub method for backlighting (dye-sub doesn’t shine through). Downsides include cost and sometimes visible seams/thick walls that can affect the click’s sound profile. In practice, these keycaps are in demand for mechanical gaming keyboards, esports arenas, developers, and frequent hotkey typing—where double-shot keeps legends readable for years.

— Sublimation. A method of applying Latin symbols to keycaps where, under heat and pressure, the dye penetrates the top layer of plastic, creating a durable, “absorbed” legend. The print won’t rub off from fingers, resists household cleaners and UV light, preserves a matte texture, and maintains high contrast on light backgrounds, but it doesn’t let RGB shine through the symbols and is limited in palette. Compared to laser...engraving, it offers higher lifespan and readability, and versus double-shot it only loses in shine-through effects. Typical use cases include mechanical keyboards for typing, developers, and office work, where durability, the tactile matte PBT feel, and stable readability over years matter.

— Laser engraving. Burning/removing the top coating layer with a beam to form highly precise symbols. Legends last for years, but over time the fill paint can wear and contrast can drop in high-contact areas. Advantages include thin typefaces, clean contours, RGB compatibility, and low cost. Compared to double-shot, engraving is cheaper and more flexible in design, but not “forever”; versus dye-sub it wins on backlighting, but loses in tactile uniformity and longevity. Typical applications are mass-market office and gaming models with backlighting.

A connector in the keyboard case for attaching a removable cable, found in both wired models and wireless ones with a battery, where through this port the keyboard is charged and, if necessary, operates "wired" without delay.

— microUSB. One of the miniature versions of the USB connector, still popular in gadgets despite the emergence of the more advanced USB-C. It has comparatively modest capabilities (in particular, it is inferior to USB-C in terms of maximum possible charging power), but this rarely proves critical. Meanwhile, there is an abundance of microUSB cables and chargers.

— USB-C. The latest (as of the end of 2025) type of USB connector. It is symmetrical, allowing the cable to be inserted either way, eliminating the possibility of incorrect connection. USB-C is more reliable, has an extended lifespan, and supports higher data transfer and charging speeds. Additionally, it is compatible with modern devices and is gradually becoming a universal standard, making keyboards with this connector more convenient and relevant for users.

Mounting the internal unit (boards and plates) through elastic gaskets around the perimeter of the case, without rigid “pulling” with screws directly. Gasket Mount often provides a more even, less resonant sound and reduces unwanted overtones, and the keystrokes feel softer compared to hard mounting schemes, though fans of a very firm setup may find it overly springy. A practical example is a keyboard for working with texts and nighttime gaming sessions, where it's important not to be noisy and to avoid catching case resonance.
