Tired of linears that sound hollow or feel inconsistent?
Cheap, Hollow Acoustics
Many PC-top switches produce a plasticky, cheap sound that ruins the premium feel of your keyboard.
Muddy, Undefined Soundscape
Uncontrolled bottom‑outs create boominess or ring, making typing feel imprecise.
Inconsistent Lubrication
Poorly lubed switches develop scratchiness or spring ping over time.
🌅 Sunset Gleam – Acoustically Refined, Visually Stunning — Modified PC top eliminates cheap plastic resonance; PA66 base adds depth without boominess. Precision lubrication (GPL105/205 on leaf & stem, dry film on springs) delivers a perfectly tuned instrument—crisp top‑out "tic", deep mahogany "thock".
Why Sunset Gleam Is the New Benchmark for Acoustic Linears
🎵 Crisp Tic + Deep Mahogany Thock
Acoustic Perfection – Like Tapping a Mahogany Desk
Feature Modified PC top eliminates the "cheap plastic" sound often associated with PC housings, while the PA66 base adds depth without boominess. The result: a crisp "tic" on top‑out and a deep, satisfying "thock" on bottom‑out.
Advantage Every keystroke sounds clean, refined, and consistent across the entire keyboard. No hollow echoes, no metallic overtones—just pure, focused acoustics.
Benefit Enjoy a premium auditory experience whether you're typing, gaming, or just listening to the rhythm of your work. The sound profile is both engaging and non‑intrusive.
Evidence Knock Knock Studio’s acoustic tuning has been praised in early reviews as “the most controlled top‑out and bottom‑out in HMX’s lineup – a genuine step forward.”
🧈 Mixed GPL105 & GPL205
🔩 Lubed on leaf, stem feet, housing rails
⚙️ Dry film lube on springs
✨ Ultra‑smooth, no scratch
🧈 Factory Lubed to Perfection
Mixed GPL105 & GPL205 – Precision Lubrication for Unmatched Smoothness
Feature HMX applies a meticulous lubrication process: GPL105 mixed with GPL205 on the leaf spring, stem feet, and bottom housing rails; dry film lube on the springs. This multi‑point approach eliminates friction and noise at every contact point.
Advantage Out of the box, the switch glides with zero scratchiness. The spring is silent, and the leaf is tick‑free. The smoothness remains consistent over millions of keystrokes.
Benefit No need to spend hours hand‑lubing—the switch is ready to deliver a premium feel from the moment you install it. Perfect for enthusiasts who demand the best without the extra work.
Evidence HMX’s proprietary lubrication process has become legendary in the community, with users noting “these are smoother than many hand‑lubed switches I’ve used.”
⚙️ 22mm KOS Stainless Spring · 42g → 48g Force Curve
Effortless press, snappy rebound⚡ Speed Meets Control
42gf Light Press → 48gf Firm Finish – The Ideal Transition
Feature 22mm KOS (Korea Ornamental Steel) single‑stage extended spring provides a linear force curve from 42g actuation to 48g bottom‑out. Pre‑travel of 2.0mm, total travel 3.5mm.
Advantage The light initial force reduces finger fatigue, while the progressive finish gives a controlled, satisfying landing. The snappy rebound maintains rhythm during rapid inputs.
Benefit Ideal for both fast‑paced gaming and marathon typing sessions. The spring’s consistency ensures that every keystroke feels the same, whether you’re spamming keys or drafting a novel.
Evidence KOS stainless steel is known for its exceptional fatigue resistance, ensuring the spring maintains its force curve for 80 million cycles.

❓ Frequently Asked Questions
What makes the Sunset Gleam sound so unique?▼
The modified PC top eliminates the hollow plastic resonance typical of PC housings, while the PA66 base adds depth without boominess. The result is a crisp, focused "tic" on top‑out and a deep, mahogany‑like "thock" on bottom‑out—a sound profile unlike any other HMX linear.
What does "KOS stainless steel spring" mean?▼
KOS (Korea Ornamental Steel) is a high‑grade stainless steel known for exceptional fatigue resistance and consistent force curves. The 22mm single‑stage extended spring provides a linear, predictable feel that remains stable over 80 million cycles.
Is 42g too light for gaming?▼
42g is ideal for competitive gaming—light enough for rapid taps but with a 48g bottom‑out that prevents accidental presses. The snappy rebound also helps maintain rhythm during intense sequences.
Do I need to lube these switches?▼
No. Sunset Gleam comes with HMX’s premium factory lubrication: GPL105/205 on the leaf, stem feet, and housing rails, plus dry film lube on the springs. They are ready to use out of the box and will remain smooth for years.
Will the 5‑pin design fit my 3‑pin hot‑swap board?▼
Yes. The two plastic positioning pins can be clipped off with flush cutters to convert to a 3‑pin switch, making it compatible with most 3‑pin hot‑swap PCBs.
What is the expected lifespan?▼
Sunset Gleam is rated for 80 million keystrokes, thanks to the durable LY stem, modified PC/PA66 housings, and KOS spring. HMX’s rigorous quality control ensures consistent performance for years.
