FAQ

Redragon COVE K733 vs K681MG Pro: your questions

No, the COVE K733 is a 22-key numpad only. It is designed as a supplementary device for users with compact keyboards that lack a number pad. You will need a separate primary keyboard for typing letters and standard commands.

The K681MG Pro uses a 75% layout, which does not include a dedicated number pad. However, it integrates a numeric keypad into a function layer on the main keys, a common space-saving feature in compact keyboards.

Both keyboards offer tri-mode connectivity (wired USB-C, 2.4GHz wireless, and Bluetooth). The COVE K733 may have an edge for portability due to its lighter weight, making it easier to move around wirelessly. The K681MG Pro's wireless performance is not detailed with specific metrics like battery life.

Yes, both the Redragon COVE K733 and the K681MG Pro feature hot-swappable sockets. The K681MG Pro's vendor description specifies full-key hot-swap compatibility with 3-pin and 5-pin switches from brands like Gateron and Akko.

The K681MG Pro's aluminum case will generally provide a more rigid, premium, and heavier feel (858g) that reduces flex. The COVE K733 uses a plastic case, which contributes to its very light 230g weight but may feel less substantial.

According to the vendor, the COVE K733 has a dedicated calculator mode with a built-in display. It allows the device to function as a standalone calculator. However, some user reviews note it may not follow standard operator precedence (e.g., multiplication before addition).

Both are space-efficient. The K681MG Pro's 75% layout saves space compared to a full-size keyboard while keeping most keys. The COVE K733 is the smallest option, taking up minimal space as it is only a numpad, but requires a separate main keyboard.

Both product listings state compatibility with macOS (Mac) and Windows. The K681MG Pro vendor page specifies compatibility with Mac in wired mode.

The vendor listing for the K681MG Pro includes a switch and keycap puller, four extra switches, and a user manual. Some bundles also include a themed Cow Farm keycap set.

Both use a gasket mount design aimed at providing a softer, more cushioned typing feel by isolating the plate from the case. The K733's description emphasizes vertical cushioning and noise reduction, while the K681MG Pro description mentions a leaf spring structure for a flexible yet stable experience.

Both have RGB backlighting. The K681MG Pro's vendor description specifies 15 preset modes, 7 pure colors, and adjustable brightness and breathing speed, controllable via a multifunction knob. The K733's RGB features are not detailed beyond its presence.
