If there is one thing that defines a premium custom keyboard in 2026, it is the sound. The pursuit of the perfect "thock"—a deep, resonant, and satisfying bottom-out—has driven enthusiasts to lubricate switches, pour silicone into their cases, and apply endless layers of tape to their PCBs.
For a long time, the consensus was that thick, double-shot PBT plastic was the best material for acoustic depth. But as hardware evolves, so do our standards. To find the true endgame of keyboard acoustics, we conducted a comprehensive sound test showdown: Popular PBT Plastic vs. Full Metal Keycaps.
Using the heavy-duty Awekeys Viking Antiques Metal Keycaps, we analyzed the sound profiles and spectrograms on two highly popular full-size boards—the Razer BlackWidow V4 X and the Wooting Two HE. Here is why metal completely outperformed plastic in our daily typing and gaming tests.

The Spectrogram Analysis: Why Materials Matter
When you listen to a keystroke, your ear is processing a complex mix of frequencies. To visualize this, audio engineers use a spectrogram.
When we analyzed standard PBT keycaps, the spectrogram revealed a scattered, jagged cluster of high-frequency sound waves. Because plastic has low mass, the energy from your keystroke causes the hollow keycap to vibrate aggressively, amplifying switch ping and creating a sharp, high-pitched "clack."
When we swapped to the Awekeys Viking Antiques metal keycaps, the spectrogram changed drastically. The high-frequency noise completely vanished. Instead, the graph showed a thick, condensed band of low-frequency energy. The sheer density and mass of the CNC-machined metal act as an acoustic black hole, absorbing the harsh vibrations and converting the kinetic energy into a deeply satisfying, muted "thud."

Showdown 1: Razer BlackWidow V4 X
The Razer BlackWidow V4 X is a staple for hardcore gamers and heavy typists who want a full-sized mechanical layout. However, out of the box, its plastic construction leaves a lot of acoustic potential on the table.
PBT Plastic Performance
On the BlackWidow V4 X, standard PBT keycaps produced a loud, unrefined typing experience. The impact of the keys against the switch housings resonated through the keyboard's chassis, creating a noticeable echo during fast typing speeds. It sounded exactly like what it is: a mass-produced gaming board.
Viking Antiques Performance
Equipping the board with the Viking Antiques completely transformed its identity. The dense metal capped the sound travel. The high-pitched plastic chatter was replaced by a rhythmic, buttery thock. It tamed the acoustics so effectively that the BlackWidow V4 X suddenly sounded like a meticulously hand-lubed, $500 custom build. For daily typing, this acoustic muting significantly reduces ear fatigue, making it perfect for shared workspaces or late-night gaming.
Showdown 2: Wooting Two HE
The Wooting Two HE is an engineering marvel, utilizing Hall-Effect magnetic switches for industry-leading Rapid Trigger performance. But magnetic switches inherently have an acoustic flaw: without physical metal leaf contacts inside the switch, the bottom-out can sound incredibly hollow.
PBT Plastic Performance
When tested with premium PBT sets, the Wooting Two HE felt incredibly fast, but it sounded empty. The lack of acoustic resistance meant that every keystroke produced a thin, "clattery" noise that undermined the premium price tag of the keyboard.
Viking Antiques Performance
The Awekeys Viking Antiques are the ultimate fix for the Hall-Effect acoustic bottleneck. The massive weight of the metal keycaps pushes down on the magnetic switches, grounding the entire board. In our sound tests, the metal keycaps effectively masked the hollow nature of the switches, introducing a rich, heavy bass note to every single keystroke. Not only did it sound phenomenal, but the added mass also provided a stable, deliberate typing feel that prevented accidental inputs during sensitive Rapid Trigger use.
The Final Verdict: Metal is the New Standard
The numbers, the spectrograms, and our ears all point to the same conclusion. While PBT was a great stepping stone, it simply cannot compete with the physics of solid metal.
The Awekeys Viking Antiques Metal Keycaps offer unparalleled acoustic dampening, shifting annoying, high-pitched clatter into a deep, luxurious thock. Combine that with a distressed, battle-forged aesthetic that will never develop an oily plastic shine, and you have the definitive upgrade for your daily driver.
