After more than 20 years using all kinds of keyboards, I had never owned anything like the XCMKB SoflePLUS2 Signature.
I am writing this review on it right now, late at night, while my wife is sleeping beside me. One of my main goals was to work, program and play at night without disturbing her, and this keyboard has exceeded my expectations.
MY CONFIGURATION
I chose the SoflePLUS2 Signature with a carbon-fiber switch plate, CF-PETG case, PORON, IXPE pads, MX hot-swap sockets, Gateron Zero Degree Fully Silent 45g switches, a large integrated glass trackpad, OLED, spinning disc, per-key RGB, and black FK Custom Cherry-profile shine-through keycaps customized in Spanish.
The carbon-fiber plate feels firm and precise, while PORON and IXPE help control vibration, resonance and sound. Together they achieve exactly what I wanted: an extremely quiet keyboard without making the keys feel soft or vague.
The Gateron Zero Degree Fully Silent 45g switches are smooth, stable, factory-lubricated linears with damping for both bottom-out and return. The result is remarkably quiet while still feeling mechanical and precise.
XCMKB REALLY LETS YOU BUILD YOUR KEYBOARD
[[****]](mailto:[****])
You can choose switches, plate, keycaps, MX or low-profile format, trackpad and other parts. I wanted very specific switches, and XCMKB sourced the exact compatible model from the official supplier and installed them for me. If what you want is not listed, I recommend contacting them directly.
CUSTOM KEYCAPS
XCMKB works with FK Custom and provides a Sofle template where you can design your own legends almost key by key:

I created black Cherry-profile shine-through keycaps with a Spanish layout, Ñ and legends adapted to my layers. My FK Custom code is TALXXZ if anyone wants it as a reference.
VIAL CHANGES EVERYTHING
Vial is one of the biggest reasons the SoflePLUS2 is so powerful and personal:

This SoflePLUS2 supports up to 10 layers, so the same physical key can perform different functions depending on the active layer: typing, programming, navigation, multimedia, applications, gaming and more.
A single key can send combinations such as Ctrl+C, Ctrl+V, Alt+F4 or Super+E. You can create macros, Combos where several keys trigger another action, and Tap Dance functions where one key behaves differently when tapped, held, double-tapped, or tapped and held. The firmware provides up to 32 macros, 32 Combos and 32 Tap Dances, plus modifiers, mouse functions, layer switching and many other QMK actions.
RGB can also be functional: individual keys can identify layers and functions visually.
SPINNING DISC AND TRACKPAD
The spinning disc has seven independent inputs. I use rotation to raise and lower my PC volume, the four directions as the Up, Down, Left and Right arrow keys, and the center button as a left mouse click.
Everything can be reassigned for scrolling, browser tabs, desktops, zoom, media, undo/redo, code navigation, brightness, RGB or IDE shortcuts, with different functions on different layers.
The large integrated trackpad lets me move the cursor, scroll and use gestures without constantly reaching for a mouse.
ERGONOMICS
Traditional staggered keyboard rows are a legacy of mechanical typewriters. A split keyboard starts from a different idea: your hands can remain separated and each half can be placed where your arms naturally fall.
The Sofle uses column stagger, following the fingers more naturally than traditional horizontal rows. For someone like me who spends many hours at a computer, the difference is very noticeable: my hands stay separated, my wrists straighter, my shoulders more comfortable, and my fingers make fewer unnecessary movements.
FAST RESPONSE FOR WORK AND GAMING
I type very quickly and have deliberately tried very fast key sequences. I have also used it for gaming. I have not noticed lag or missed keypresses; the response feels immediate. I would recommend it 100% for work, writing, programming, productivity and demanding competitive gaming.
THANK YOU, XCMKB
After more than 20 years trying keyboards, I have never owned one combining this level of materials, ergonomics, silence, responsiveness, customization and typing feel.
I am finishing this review while my wife is still sleeping without being disturbed by my keyboard. That is exactly what I wanted: to be able to work and play without disturbing her.
I also want to thank Jin and the entire XCMKB team. They were patient with my questions, listened carefully to what I wanted, tested options, helped me obtain the components I had chosen and built a keyboard that exceeded my expectations.
XCMKB has definitely become my favorite keyboard manufacturer. I sincerely hope this will not be the last keyboard I buy from them.
I recommend the SoflePLUS2 Signature 100%. Five stars without any doubt.
