Gaming Features
- Includes a Rapid Trigger feature, which is advantageous for competitive gaming.
- Explicitly supports both Mac and Windows systems out of the box.
- Slimmer profile (29mm height) for a potentially more portable and ergonomic setup.

Fl·esports FL Esports CMK75 vs LANGTU LT84: your questions
The FL·ESPORTS CMK75 is designed for a softer typing feel. It uses a gasket mount and a slotted PC positioning plate, which the manufacturer states provides a 'silky smooth' experience. The LANGTU LT84 uses a sandwich mount, which typically results in a firmer, more direct feedback.
Yes, rapid trigger is listed as a feature in the LANGTU LT84's metadata. This is a gaming-oriented function that allows for faster keystroke resetting, which can be beneficial in fast-paced competitive games.
Both keyboards use standard ANSI layouts, so physical keycap compatibility is the same. However, the LANGTU LT84 explicitly lists 'Mac/Win Support' in its features, suggesting its firmware or included keycaps may have better out-of-the-box mapping for macOS.
The vendor description for the LANGTU LT84 specifically mentions an 'extra-long battery life'. There is no comparable claim made in the provided description for the FL·ESPORTS CMK75, suggesting the LT84 may have an advantage in this area.
Only the FL·ESPORTS CMK75 is confirmed to have south-facing RGB LEDs, as stated in its metadata and vendor description. South-facing LEDs prevent interference with Cherry-profile keycaps. The LANGTU LT84's listing does not specify LED orientation.
The CMK75 uses a multi-layer design with PORON cotton, an IXPE under-shaft pad, and bottom padding. The LT84 uses a triple-layer design with EVA cotton padding, bottom rubber padding, and undershaft silicone padding. Both are designed to reduce case resonance.
Yes, both the FL·ESPORTS CMK75 and LANGTU LT84 feature full-key hot-swappable sockets. This means you can replace the mechanical switches without any soldering required, using compatible aftermarket switches.
Yes, both keyboards feature a screen. The CMK75 has a 'Colorful TFT Display Screen' and the LT84 has a 'Multi-Function Colorful Display Screen'. Both vendor descriptions state the screens can be customized with images or GIFs.
The core mechanical difference is the mount style. The FL·ESPORTS CMK75 uses a gasket mount, where the plate is suspended on soft gaskets. The LANGTU LT84 uses a sandwich mount, where the plate is fixed between the top and bottom case layers. This fundamentally changes the typing feel and sound.
Based on listed dimensions, the LANGTU LT84 is significantly slimmer with a height of 29mm compared to the CMK75's 46mm. This lower profile makes the LT84 easier to pack into a bag or laptop sleeve, giving it a portability edge.
According to its vendor description, the FL·ESPORTS CMK75 is available with customized Glacier Pink (linear), Glacier Purple (tactile), and Kailh Box Marshmallow switches. The metadata also confirms it offers linear, tactile, and clicky switch types.
