The AULA S99 is an ultra-budget, 96% compact wireless keyboard featuring a 99-key layout, tri-mode connectivity (2.4GHz, Bluetooth 5.0, USB-C), an integrated LED digital screen, and a media control knob. Powered by a 2000 mAh battery, it utilizes a membrane volcano design providing a tactile, quiet typing feel suitable for daily office use and casual gaming.
What is the AULA S99? Layout, connectivity (96% tri-mode wireless) and key specs
The AULA S99 brings a 96% compact form factor with 99 keys, keeping the dedicated number pad and arrow keys while trimming down desktop space compared to standard 104-key full-sized boards. Its shell and keycaps are constructed from ABS plastic.

What switch options does the AULA S99 come in?
Unlike mechanical keyboards with individual physical switches, the AULA S99 uses an internal membrane dome sheet with a volcano stem design. This structure gives keypresses a soft, cushioned bottom-out with quiet sound performance.
| Variant Name | Key Structure / Feel | Product Code |
| AULA S99 Grey+White | Membrane (45g soft-tactile actuation) | S99WGr |
| AULA S99 Blue+White | Membrane (45g soft-tactile actuation) | S99UW |
Honest limitation: Because this board utilizes an integrated membrane structure, there are no hot-swappable mechanical switches to replace or lubricate. What you buy is fixed to the stock membrane feel.
How does the AULA S99 feel to type and game on?
Based on the manufacturer's listed specs, the 45g actuation force and 3.8mm key travel provide a light, comfortable bounce for extended typing sessions. The membrane dome structure absorbs impact noise, preventing the heavy clack or click associated with mechanical options.
For casual gaming (single-player titles, RPGs, relaxed office work), the key response is reliable.
Honest limitation: Membrane key structures lack the distinct actuation feedback and rapid-reset speeds of dedicated mechanical switches. Competitive esports players who rely on rapid double-taps or instant key resets may find the bounce rate slower than dedicated mechanical offerings.
Wireless: how do Bluetooth, 2.4GHz and wired modes work on the AULA S99? Battery life
The AULA S99 features tri-mode connectivity:
-
2.4GHz Wireless: Uses the included USB dongle stored in the keyboard body. Toggling the physical switch to 2.4G delivers low-latency connection for gaming.
-
Bluetooth 5.0: Connects across multiple devices (laptops, tablets, phones) via key combinations.
-
USB Type-C Wired: Connects using the included detachable cable while actively charging the battery.
According to manufacturer figures, the built-in 2000 mAh battery offers up to approximately 50 hours of continuous use with RGB backlighting active, and up to 300 hours with backlighting turned off.
Honest limitation: The 2000 mAh capacity is notably smaller than the higher-tier mechanical models in AULA's lineup (like the 8000 mAh battery found in the F99), requiring more frequent recharge cycles if you keep RGB effects at full brightness.
AULA S99 vs AULA F99 vs AULA F87
Comparing the budget membrane S99 against AULA's popular mechanical platforms:
| Feature | AULA S99 | AULA F99 | AULA F87 |
| Layout | 96% (99 Keys) | 96% (99 Keys) | 80% TKL (87 Keys) |
| Switch Type | Membrane (Volcano design) | Mechanical (Hot-swappable) | Mechanical (Hot-swappable) |
| Keycap Material | ABS | PBT | PBT |
| Hot-Swap Support | No | Yes (3-pin / 5-pin) | Yes (3-pin / 5-pin) |
| Battery Capacity | 2000 mAh | 8000 mAh | 4000 mAh |
| Display / Knob | LED Display & Media Knob | Varies by sub-variant | Knob on select editions |
| Target User | Budget office & casual gaming | Mechanical enthusiast / Gamer | Space-saving TKL enthusiast |
Software, hot-swap and customization: what can you change?
-
Hot-Swapping: The AULA S99 is not hot-swappable. The keys sit atop a rubber membrane layer rather than PCB mechanical sockets.
-
Keycaps: Keycaps use volcano stems, making standard MX-compatible aftermarket keycap sets incompatible.
-
Software: On Windows, programmable software supports macro remapping and adjusting dynamic lighting modes. You can also adjust lighting patterns directly from the top-right knob and function shortcuts.
Honest limitation: Customization options on the hardware side are low. You cannot swap mechanical switches, replace keycaps with custom PBT Cherry-profile sets, or modify internal gaskets.
AULA S99 price in India and where to buy
The AULA S99 retails in India at an MSRP of ₹4,999, typically available at sale prices around ₹2,099. This places it among the most affordable wireless 96% keyboards featuring a dedicated number pad, screen, and control knob.

Frequently Asked Questions
Is the AULA S99 good for gaming?
The AULA S99 performs well for casual gaming, story titles, and everyday desk work thanks to its 2.4GHz low-latency wireless connection. However, because it uses a membrane mechanism rather than fast mechanical switches, hardcore competitive FPS players may prefer mechanical alternatives like the AULA F99.
Is the AULA S99 hot-swappable?
No, the AULA S99 is not hot-swappable. It uses an integrated membrane volcano design rather than individual mechanical switch sockets. If you require hot-swappable mechanical switches, look at the AULA F series (such as the F87 or F99).
Does the AULA S99 work with Mac?
Yes, the AULA S99 works with macOS, Windows, Android, and iOS devices using Bluetooth, 2.4GHz wireless, or USB-C wired connections. Standard typing functions and number pad keys operate across operating systems, though dedicated software customization is geared for Windows.
What is the price of the AULA S99 in India?
The AULA S99 carries an official list price of ₹4,999 and regularly sells online in India for approximately ₹2,099 depending on active store promotions.
Which AULA S99 switch should I choose?
The AULA S99 does not offer traditional individual mechanical switch options (such as Red, Blue, or Brown switches). Both color variants feature the same 45g membrane structure, so your choice comes down purely to visual preference between the Grey+White or Blue+White aesthetic.
