HMX Sunset Gleam (Duck Duck) — Warm Sound Smooth Linear | Factory Lubed · Custom Build
HMX Sunset Gleam Linear
Tired of hollow, cheap-sounding linears? Sick of spending 10 hours hand-lubing scratchy switches just to make them tolerable?
Custom keyboard manufacturing titans HMX and Knock Knock Studio have teamed up to drop the absolute endgame in acoustics and typing feel—the "HMX Sunset Gleam" (aka Duck Duck Switch).
This linear switch perfectly fuses top-tier acoustic tuning with insanely strict factory pre-lubing. Breaking the mold, it uses a golden combination of a modified PC top and a PA66 bottom housing to deliver a distinct dual-tone profile: a crisp top-out "Tic" and a deep bottom-out "Thock." Armed with an ultra-low friction LY stem, a fatigue-free 42gf feather-light press, and a 22mm KOS stainless steel extended spring, it makes every keystroke flow like water. Whether you're chasing the pure ASMR typing experience or sweating out ranked esports matches, the Sunset Gleam is your final stop.
Core Advantages: The New Benchmark for HIFI Linears
We know the Keeb community's ears and fingers are equally picky. The Sunset Gleam was engineered to completely eradicate hollow ping, scratchiness, and typing fatigue.
The Problem: Hollow Plastic Ping
Many switches with standard PC (Polycarbonate) housings produce a thin, scattered sound that screams "cheap plastic." Uncontrolled bottom-outs create an irritating metallic resonance.
The Problem: The Hand-Lubing Hassle
Standard factory lube jobs are incredibly inconsistent. Switches get scratchy, develop sandy friction, and suffer from loud spring ping, forcing you to become a "lube slave" for hours.
The Problem: Fatigue & Mushy Reset
Overly light springs cause accidental misinputs and a mushy rebound, while heavy springs (55gf+) cause severe finger cramp and fatigue during long gaming or coding sessions.
Kill Hollow Ping
Crisp Tic & Deep Thock Acoustics
Uses an acoustically optimized modified PC top housing (to eliminate cheap resonance) paired with a modified PA66 nylon bottom housing (to thicken the sound without muffling it).
This brilliant material clash creates its signature dual-tone: a remarkably clean, crisp "Tic" on the upstroke, and a deep, resonant "Mahjong Thock" on the bottom-out.
Every keystroke is an intensely therapeutic auditory climax. It sounds like you are typing on a thick slab of premium mahogany wood. No hollow echoes, no metallic ping—just pure, focused ASMR.
End The Hand-Lubing Hassle
LY Stem & HMX God-Tier Factory Lube
Armed with an ultra-low friction LY material stem and HMX’s famously strict multi-point precision lube process (GPL105+205 mix on the leaf, stem legs, and rails; dry film lube on the spring).
The dry film lube completely kills spring ping. The LY stem gliding against the precision-lubed rails faces absolutely zero resistance.
Save yourself dozens of hours of tedious hand-lubing. This switch reaches peak buttery smoothness the exact second you open the box, and stays that way for millions of keystrokes.
End Fatigue & Mushiness
42gf Cloud Press & 22mm KOS Spring
Meticulously tuned to a 42gf actuation and a 48gf bottom-out, powered by a highly fatigue-resistant 22mm Korean KOS (Korea Ornamental Steel) single-stage extended spring.
The 42g weight is light and breezy, perfect for marathon typing. Meanwhile, the 22mm KOS spring provides excellent initial support and an incredibly crisp, snappy rebound.
Hits the absolute "sweet spot" between agile response and solid physical confirmation. The progressive linear feel makes it the ultimate ergonomic weapon for both rapid esports reactions and all-day typing.

Real Reviews from the Keeb Community
"The ultimate revelation in switch acoustics!"
"The sound on the Sunset Gleam is absolutely unreal. The top-out 'Tic' is pristine, and the 'Thock' on the bottom-out is deep without being muffled. It literally sounds like my fingers are drumming on a premium solid wood desk. Incredibly addictive."
"HMX factory lube never disappoints. Butter smooth."
"Finally, a switch where the sound and feel are equally god-tier. The factory GPL105+205 mix is flawless—smoother than switches I've spent hours hand-lubing. The 42g weight is the absolute perfect sweet spot for marathon gaming."
"The KOS long spring rebound is so snappy."
"The 22mm Korean KOS spring breathes so much life into this switch. The rebound is aggressive, crisp, and snappy, perfectly maintaining my typing rhythm. Paired with the LY stem, this is easily the most elegant linear switch HMX has ever produced."
