Epomaker EK21 vs Firstblood B6: your questions
The core difference is layout and function. The EK21 is a full 20-key numeric keypad with a knob, designed for data entry and fully programmable via VIA. The B6 is a 6-key macropad, intended for a few customizable keys or media controls in a much smaller acrylic case.
The vendor description for the B6 mentions a combination key function for gaming and media control, but it does not specify any companion software for user programming like VIA. The EK21 explicitly supports VIA for full key remapping and macro creation.
The Epomaker EK21 has a larger 1000mAh battery compared to the Firstblood B6's 600mAh battery. While the B6's listing claims up to 24 hours with backlights off, the EK21's larger capacity should generally provide longer usage between charges, especially with its RGB lighting on.
Yes, both the Epomaker EK21 and the Firstblood B6 are hot-swappable. The EK21's listing specifies compatibility with 3-pin and 5-pin mechanical switches.
No, according to the provided specifications, the Firstblood B6 does not have RGB lighting. The Epomaker EK21 does feature dynamic RGB backlighting.
The Epomaker EK21 has a 1000Hz polling rate in its wired and 2.4GHz wireless modes. In Bluetooth mode, the polling rate is 125Hz.
The Epomaker EK21 uses PBT keycaps with a dye-sublimated printing technique. The Firstblood B6 uses PC (polycarbonate) keycaps in an SA profile, which are clear according to the vendor description.
The Epomaker EK21 is likely quieter stock due to its gasket-mount design and three layers of sound-dampening foam (Poron and IXPE). The Firstblood B6's listing does not mention any built-in sound dampening materials.
The EK21 comes with the numpad, a 2-in-1 keycap and switch puller, an extra 'Back' keycap, a 1.8m detachable braided USB A-to-C cable, a 2.4GHz wireless dongle, and a multilingual manual.
The B6's vendor page suggests its combination keys can be used for continuously releasing attacks in games. However, for gaming, the EK21 is a stronger choice due to its specified 1000Hz polling rate, N-Key Rollover, and the ability to program its knob for game functions.
Yes, both the Epomaker EK21 and Firstblood B6 list compatibility with Mac operating systems in their specifications.
The Firstblood B6 is heavier at 296 grams, despite its smaller size, likely due to its thick acrylic case. The Epomaker EK21 weighs 200 grams.
