Epomaker EK21 vs Leobog K21: Gasket Mount vs Plate Mount Numpads

Compare Epomaker EK21 vs Leobog K21 Differences Side by Side

This comparison is for users choosing between two similarly priced, triple-mode wireless mechanical numpads. The decision is difficult because both offer hot-swap sockets, PBT keycaps, and polycarbonate plates. The core trade-off lies in the Epomaker EK21's advanced gasket mount construction and VIA software support against the Leobog K21's potentially simpler, transparent design and different default switch.

Pros and Trade-offs

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.

Epomaker EK21

+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.
+Larger 1000mAh battery capacity for extended wireless use.
+Specified 1000Hz polling rate in wired and 2.4GHz modes.

−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.

Leobog K21

+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.
−Polling rate is not specified in the provided information.

Which Keyboard Is Better for Your Needs?

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.

GamingEpomaker 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.

OfficeEpomaker EK21

•The EK21 includes a programmable aluminum knob for volume or macro control, a feature not mentioned for the K21.
•The EK21's larger 1000mAh battery may offer longer wireless use between charges compared to the K21's 600mAh battery.
•Both offer triple-mode connectivity for flexible desk setups.

ProgrammingEpomaker EK21

•The EK21 is fully programmable via VIA software, allowing deep key remapping and macro creation, which the K21's listing does not specify.
•The hot-swappable PCB on both allows for switch customization to suit typing preferences.
•The EK21's flex-cut PCB and plate, combined with its gasket mount, may offer a more comfortable typing experience for long sessions.

TravelTie

•Both numpads weigh 200g and have compact, numpad-sized layouts.
•Both feature triple-mode wireless connectivity, eliminating the need for a cable on the go.
•The EK21's larger battery is an advantage, but the K21's potentially smaller footprint (82mm width vs 138mm) could be easier to pack.

ModdingEpomaker EK21

•The EK21 features a gasket mount structure with three layers of foam (Poron and IXPE) for sound tuning, a detail not provided for the K21.
•The EK21's listing specifies a flex-cut PCB and plate for extra flexibility, offering more modding potential.
•Both have hot-swappable PCBs compatible with 3-pin and 5-pin switches.

Content CreationEpomaker EK21

•The EK21's programmable knob can be mapped to timeline scrubbing, brush size, or other creative software parameters.
•VIA software support on the EK21 allows for creating complex macros for editing workflows.
•The dampened, gasket-mounted sound profile of the EK21 may be preferable for quiet recording environments.
