What will you mostly use it for?
The Niz S104 wins for office work and content creation where a numpad is essential. The Niz X99 is the better choice for travel or small desks due to its more compact 96% layout. For gaming, programming, and modding, the keyboards are effectively tied, sharing identical switch technology, programmability, and construction. Your desk space and need for a numpad are the primary deciding factors.
It's a tie
- Both use the same 35g electro-capacitive switches.
- Both are wired-only with USB-C connectivity.
- Neither offers RGB lighting, focusing on a clean aesthetic.

Niz S104 EC vs X99: your questions
The main difference is the layout size. The S104 is a standard 100% keyboard with 104 keys and a separate numpad. The X99 is a 96% keyboard with 99 keys, integrating the numpad into the main cluster to reduce its overall length from 446mm to 380mm.
Yes. According to the vendor descriptions, both keyboards use 35g electro-capacitive switches. The construction for both involves a rubber dome with a slider, topped with a coil spring.
No. Both the Niz S104 and X99 are wired-only keyboards. They connect via a USB-C cable, as stated in their specifications and descriptions.
Yes. The manufacturer states that both the S104 and X99 are freely programmable and macro-compatible. This allows you to reassign keys and create complex key sequences.
Both keyboards come with PBT (Polybutylene Terephthalate) keycaps. The vendor specifically mentions they are two-colour keycaps, which are durable and resistant to oil buildup from fingers.
No. Neither the Niz S104 nor the X99 have any form of backlighting or RGB lighting. This is confirmed in the specifications and the vendor description for the S104 which explicitly states 'Backlight:no'.
The Niz S104 weighs 1160 grams, while the Niz X99 is slightly heavier at 1249 grams. Both are substantial, weighty boards made primarily from plastic.
The product descriptions do not mention hot-swap sockets. They are described as pre-built electro-capacitive keyboards. However, the vendor notes that 10g springs are included for adding to the switches, suggesting some spring modification is possible.
The Niz X99 is better for a small desk. Its 96% layout measures 380mm in length, which is 66mm (over 2.5 inches) shorter than the 446mm long S104. This compact form saves significant desk space while keeping most keys accessible.
Yes, but it is integrated. The Niz X99 is a 96% layout, which means it includes a numpad but it is condensed and merged with the main key cluster, eliminating the space typically between the main keys and a standalone numpad.
The vendor descriptions do not provide a detailed list of included accessories. However, they mention that the keyboards come with 10g springs (40-50 pieces) for adjusting the switch weight, and they feature a two-stage support leg structure and anti-skid pad.
