Epomaker EK21
Gasket Mount
- Gasket mount structure with Poron and IXPE foam layers for a cushioned, quiet typing feel.
- Full programmability and macro support via VIA software.
- Includes a customizable aluminum alloy knob for media or macro control.
- Some user reviews mention persistent software or firmware issues with VIA.
- Lacks the transparent case aesthetic offered by the K21.
- Wider footprint (138mm) may take up more desk space.
Get the
Leobog K21
Plate Mount Numpads
- Offers a transparent case design, according to its vendor title.
- Includes hot-swappable PCB for easy switch changes.
- Triple-mode connectivity provides wired and wireless flexibility.
- Uses a simpler plate mount design instead of a gasket mount.
- Smaller 600mAh battery capacity.
- No mention of advanced programming software like VIA; vendor lists a separate Windows driver.
For most users, the Epomaker EK21 is the recommended choice due to its superior gasket-mounted typing experience, VIA programmability, and included control knob. Opt for the Leobog K21 primarily if you specifically desire a transparent aesthetic and are satisfied with a more basic, plate-mounted construction and lack of detailed programmability. Both serve as functional wireless numpads, but the EK21 offers more features for its price.

What will you mostly use it for?
The Epomaker EK21 is the more capable and customizable option, winning in most categories. Its advantages in programmability, build construction, and included knob make it stronger for gaming, office work, programming, and content creation. For modding, its detailed foam layers and flex-cut design offer a better starting point. The two are closely matched for travel due to identical weight and wireless features, with trade-offs between battery life and potential dimensions.
Pick the Epomaker EK21
- The EK21 has a specified 1000Hz polling rate in wired and 2.4GHz modes, which the K21's listing does not mention.
- Both support N-key rollover for simultaneous key presses.
- The EK21's gasket mount with foam layers may provide a more consistent, dampened feel during rapid input.

Epomaker EK21 vs Leobog K21: your questions
The Epomaker EK21 is designed for a more premium typing feel. It uses a gasket mount structure with Poron bottom foam, sandwich foam, and an IXPE switch pad to cushion each keystroke and reduce noise. The Leobog K21 uses a standard plate mount system, which typically provides a firmer, less dampened feel.
The Leobog K21's product listing does not mention VIA or QMK support. The vendor page provides a link to a separate 'LEOBOG K21 Software Download Driver' for Windows, suggesting some level of programmability, but its scope is unclear. The Epomaker EK21 explicitly supports full key remapping and macro creation through VIA software.
Yes, the Epomaker EK21 includes an aluminum alloy knob. According to the manufacturer, it can be used for volume adjustment by default and its function can be fully customized using the VIA software.
The Epomaker EK21 has a 1000mAh battery, while the Leobog K21 has a 600mAh battery. While actual runtime depends on usage and lighting, the EK21's larger capacity suggests it will last longer between charges under similar conditions.
Yes, both the Epomaker EK21 and Leobog K21 list Mac and Windows support in their specifications. The EK21's listing also includes Android compatibility.
The Epomaker EK21 specifies a 1000Hz polling rate in both its wired and 2.4GHz wireless modes, which is a common standard for gaming peripherals. The Leobog K21's product information does not specify a polling rate, making a direct comparison on this point impossible.
Yes, both the Epomaker EK21 and Leobog K21 feature hot-swappable PCBs. They are compatible with most 3-pin and 5-pin mechanical switches, allowing you to easily install your preferred switches without soldering.
The Epomaker EK21 uses dye-sublimated PBT keycaps. The Leobog K21's specifications list its keycap material as both PBT and ABS, but does not specify which material is used on which version or key.
The vendor page titles the product 'LEOBOG K21 Transparent Wireless Number Pad,' indicating a transparent case design is a key feature. The Epomaker EK21 does not offer a transparent case option.
According to the manufacturer, the Epomaker EK21 includes the numpad, a 2-in-1 keycap and switch puller, an extra 'Back' keycap, a 1.8m detachable USB-C cable, a 2.4GHz wireless dongle, and a manual. The Leobog K21's package includes a Type-C cable, a 2.4G dongle, and a user manual.
Yes, both numpads feature RGB backlighting. The Epomaker EK21 has dynamic RGB, and the Leobog K21's specs list RGB and white lighting options.
