Frequently Asked Questions
Why do competitive gamers overwhelmingly prefer Cherry profile keycaps?
Cherry profile is lower in height (9.4mm on home row) than OEM (11.9mm) and SA (16.5mm), keeping wrists at a flatter, neutral angle. Its gentle cylindrical sculpt cradles fingertips without requiring your fingers to climb over high sculpted borders, minimizing fatigue during rapid WASD movements and strafing.
What causes the deep bass 'Thock' sound in mechanical keyboards?
Acoustic resonance in a keycap is determined by internal air cavity volume and wall thickness. High-profile keycaps like SA and MT3 enclose significantly more empty space inside the cap, acting like an acoustic echo chamber that amplifies low-frequency reverberations (150Hzโ250Hz 'thock'). Thicker 1.5mm PBT plastic dampens high-pitch bottom-out plastic clicks.
What is the difference between Sculpted and Uniform keycap profiles?
Sculpted profiles (Cherry, OEM, SA, MT3) feature different heights, angles, and slopes on each row (R1 to R4) so keys angle toward your fingers in a curved arc. Uniform profiles (XDA, DSA) have the exact same flat height on every single row, allowing keycaps to be placed on any switch regardless of row layout.
Do I need a wrist rest with SA or MT3 keycaps?
Yes! High-profile keycaps raise the top typing surface by an extra 5mm to 7mm above standard keyboards. Typing on SA or MT3 without a wrist rest forces severe wrist extension (bending upwards), causing carpal tunnel compression and extensor tendon strain over long gaming sessions.
