Meet the Core Features of NJ98-CP V4S

Instantaneous Key Registration

The Tech:8,000Hz Polling Rate & 0.125ms Latency.
What you’ll feel:Standard gaming keyboards update your PC 1,000 times a second while keydous NJ98 HE V4 updates 8,000 times a second. The absolute instant your finger twitches, the action registers on screen. In clutch moments in Valorant,Apex Legends, or OSU!, this microscopic speed advantage is the difference between winning the duel and heading back to the lobby.

Flawless Rapid Triggering

The Tech:32kHz Scanning & 256k Sampling Rate.
What you’ll feel:The keyboard scans the exact position of your keys 32,000 times per second. This means features like Rapid Trigger are incredibly precise, with zero "dead zones." Your counter-strafing is instant, your jiggle-peeks are pixel-perfect, and your movement feels unbelievably responsive.

Wireless Freedom

The Tech:Dual-Mode 8,000Hz (Wired & 2.4GHz Wireless).
What you’ll feel:Most wireless keyboards force you to choose: the convenience of wireless (stuck at a laggy 1,000Hz) or the speed of a cable. Enjoy pristine, zero-lag, 8,000Hz esports performance entirely cord-free. No cable drag, no signal drop, just pure speed.

Smart Battery & System Control

The Tech: On-the-Fly Rate Switching (1k/2k/4k/8k).

What you’ll feel:Running 8,000Hz wireless all day can drain battery and take up CPU resources. With on-the-fly switching, you can instantly drop to 1,000Hz for casual typing or office work to save battery, and instantly crank it up to 8,000Hz the second you launch your favorite competitive game—all without needing to open bloated software.

Instantaneous Stopping Power

The Tech: 0.01mm Rapid Trigger & Zero Dead Zone Toggle.
What You Feel: Traditional keys must travel back up to reset. With a 0.01mm reset threshold (thinner than a strand of hair) and Zero Dead Zones, the very millisecond you begin to lift your finger, the key deactivates. In tactical shooters like CS2 and Valorant, this means instantaneous, pixel-perfect counter-strafing. You stop on a dime, your crosshair tightens immediately, and you land the first shot before your enemy can even react.

Full Customized Key Map

The Tech: 0.1mm to 3.3mm Actuation with 0.01mm Micro-Precision.
What You Feel: No two gamers have the same touch. This ultra-fine precision lets you tailor individual keys to your exact playstyle. Set your movement keys (WASD) to a hair-trigger 0.1mm for lightning-fast dodges, while setting your critical abilities (like your Ultimate) deeper to 2.0mm+ to completely eliminate accidental fat-finger misclicks. It is ultimate control, customized to your exact muscle memory.

Dual-Layer Key Configurations

Featuring dual-layer keymaps, it supports full customization—one optimized for office productivity, the other for high-performance gaming—allowing you to seamlessly switch between scenarios.

Last-Input Priority (SNAP)

Instantly prioritizes the latest keypress without needing to release the previous key, drastically accelerating key response and unlocking hyper-flexible in-game movement.

Multi-stage triggering with dynamic key resistance

Each keypress supports up to 16 sequential activations across different travel depths. In-game, a gentle press on the "Q" key lets you walk, while bottoming it out instantly triggers a full run.

Alternatively, map a seamless combo to a single keypress—like Q+W to sprint and unleash a skill simultaneously—optimizing your execution for lightning-fast, game-winning plays.

Seamless macro execution with continuous multi-stage triggering

Once a key reaches a specific travel depth, it can continuously output inputs, instantly stopping when a new action is triggered at the next stage. For example, in-game, you can bind a continuous sprint to fully pressing down the 'A' key, and automatically execute an 'F' key skill the moment you release 'A'. This enables fluid, zero-latency combat combos.

Magnetic Docking Screen

Upload your favorite images to cutomize the little screen,adding a little enjoyment to relax your mind amidst the heavy workload.

A maximum of 8 images(3 gif and 5 static) can be uploaded and interchanged.

This Keydous NJ98 V4S TMR is really nice!

I really enjoy my new Keydous NJ98 V4S TMR. It's fast in response time, very fast. The cool screen is very useful with it's different modes. The knob is made out of metal and is also useful to change the volume. Great battery life, especially when turning off the screen and RGB lights on the keyboard. Up to 800 hours i think. So nice with a numberpad again but i would prefer to also see the print screen button.
