The AULA HERO 75 HE is the pick of the three for going cordless; the other two stay on a cable. The HERO 84 HE adds a 36-LED light box, and the AG75 puts 0.001mm Rapid Trigger in a CNC aluminium case. All three poll at 8000Hz and carry 2 years of warranty at Evetech.
Three AULA keyboards share the same basic recipe: magnetic switches, a 75% layout, 8000Hz polling and a two-year local warranty. On a spec sheet they can look almost interchangeable. In practice they are aimed at quite different people, and the differences sit in the connection, the build and the lighting. This comparison of the HERO 75 HE vs HERO 84 HE vs AG75 lays out what they share, where they part ways and who each one suits.
The AULA HERO 75 HE is the pick of the three if you want to go cordless; the HERO 84 HE and AG75 stay on a cable. The HERO 84 HE is a wired 75% board with a 36-LED light box, and the AG75 puts 0.001mm Rapid Trigger inside a full CNC aluminium case. All three poll at 8000Hz and carry a 2 Years Local Warranty at Evetech. Evetech's prices for the trio are R719 for the HERO 84 HE, R899 for the HERO 75 HE, R2,399 for the AG75 Ultra and the Shadow Grey AG75 Pro, and R2,799 for the Armor Silver AG75 Pro.
Before the differences, the shared ground:
If those five things are your must-haves, any of the three will do the core job. The choice comes down to how you want to connect, how you want the board built and how it should look.
The HERO 75 HE is the only board of the three with a battery. It is tri-mode: a USB-C cable, a 2.4GHz receiver and Bluetooth for up to three devices. The key point for gamers is that the receiver runs at the same 8000Hz as the cable, so going wireless does not cost polling rate. Bluetooth runs at 125Hz and is meant for laptops and tablets.
It runs on an 8000mAh battery, though AULA publishes no battery-life figure. Its magnetic switches depend on colour: Stormrise on the black board, Spiritcloud on the orange and green. You can place the actuation point anywhere between 0.1mm and 3.4mm, moving in 0.005mm increments, and remove the dead zone entirely. Under the PBT double-shot caps, an aluminium alloy plate sits over five dampening layers in what AULA calls a boat-style chassis. It measures about 313 x 139 x 43mm and weighs about 980g without the cable.
The HERO 84 HE shares the HERO look but stays on a cable, supplied as an L-shaped USB-A to USB-C lead. It comes in white and purple, with pre-lubed Black King magnetic switches rated at 33gf actuation and 53gf bottom-out. Its actuation range is also 0.1mm to 3.4mm, set in 0.01mm increments, with Rapid Trigger on top, and key scanning reaches up to 128kHz on a single key.
Its lighting is its signature: per-key south-facing RGB plus a 36-LED neon light box along the top, which AULA says runs its own modes, colours, speed and brightness, independent of the keys. Five dampening layers sit inside the case.
The AG75 is the premium build of the three. Its full CNC-machined aluminium case is sandblasted and anodised, six layers of dampening sit under a carbon fibre plate, and a switchable spring base adds shock absorption. The case opens without tools through a ball-catch quick-release structure, which makes it the easiest of the three to take apart for customising.
It comes as the AG75 Pro, with LEOBOG Frostcore magnetic switches in Shadow Grey or Armor Silver, and the AG75 Ultra, with LEOBOG Eight Treasures switches in Battle Shine Orange and PBT dye-sub and transparent keycaps. Both run 0.001mm Rapid Trigger with a zero dead zone, and a triple-MCU design with 256kHz full-key scanning. The AG75 has 81 keys and twin-star RGB, lit from above and below by 170 LEDs.
The AG75 quotes the smallest number, 0.001mm Rapid Trigger. The HERO 75 HE adjusts actuation in 0.005mm steps, and the HERO 84 HE in 0.01mm steps. These figures describe slightly different things, and all three are far finer than any finger can control, so treat them as a sign of sensor resolution rather than a reason to pick one board over another.
The AG75 weighs about 1532g without its cable, thanks to that aluminium case. The HERO 75 HE is about 980g. AULA does not list a weight for the HERO 84 HE. A heavier board stays put on the desk; a lighter one is easier to carry to a friend's place or a LAN.
Both HERO boards have the 36-LED light box; the AG75 does not, using twin-star key lighting instead. If the neon strip is what draws you to the HERO look, the choice is between the two HEROs.
The HERO 75 HE and AG75 both list SOCD, DKS, Multi-Point Trigger, Mod-Tap, Toggle and END, and the AG75 adds Rapid Switch and macros. The HERO 84 HE's page names Mod-Tap and Dynamic Keystrokes in its web driver.
If you want a clean desk or move between a PC and a laptop, yes: it is the only magnetic board in AULA's range that goes wireless without dropping below 8000Hz on its receiver. If your board never leaves one desktop, a wired option saves you a battery to look after.
You want the HERO light box and a simple wired setup, and you like a white and purple colourway.
Build quality matters most. The aluminium case, carbon fibre plate, tool-free opening and full advanced mode list make it the enthusiast's option.
All three sit in Evetech's gaming keyboards category. Because each is hot-swappable, the keyboard switches collection is worth a browse later, keeping to magnetic switches that suit each board.
Magnetic switches, a 75% layout, 8000Hz polling, hot-swap sockets and two years of local cover.
