Compare Leopold FC900R OE vs FC900RBT Differences Side by Side

This comparison is for buyers who want a premium, full-size mechanical keyboard from Leopold but are split between a purely wired model and one with Bluetooth. The decision is tough because both boards share the same 104-key ANSI layout, genuine Cherry MX switches, sound dampening, and dual-shot PBT keycaps. The core trade-off is connectivity: the OE is wired-only, while the RBT adds Bluetooth 5.1 and USB-C wireless support for desk-free use.
