Keychron Q3 Ultra 8K Black Brown Switch (ISO-CH)

Keychron Q3 Ultra 8K Black Brown Switch (CH) – 8K Wireless TKL made of aluminum

Ideal for beginners

The Keychron Q3 Ultra 8K combines a compact 80% TKL format with a Swiss ISO-CH layout, wireless freedom and a pleasantly rich typing feel. By dispensing with the number pad, there is more space for the mouse, while arrow keys and function keys are completely retained. This makes it comfortable for gaming, office, home office and longer typing sessions. The pre-installed Keychron Silk POM Brown switches work tactilely and provide clearly noticeable feedback when triggered. This is exactly what makes them interesting when linear switches seem a bit too smooth, but clicky models are too loud. The switches are already lubricated from the factory and combine controlled typing with a pleasantly restrained sound.

For IT professionals & enthusiasts

The case of the Keychron Q3 Ultra 8K is CNC-machined from 6063 aluminum and brings a lot of substance to the desk at 1787 g ± 10 g. Inside, a PC plate works together with the double-gasket construction and several acoustic damping layers. This reduces distracting resonances and ensures a controlled, full sound. The keyboard supports hot-swap and is compatible with most mechanical 3-pin and 5-pin MX switches. Soldering is not necessary. Screw-down PCB stabilizers keep large keys such as Spacebar, Enter, Shift and Backspace stable. In addition, there are KSA Double-Shot PBT keycaps with durable legends. 2.4 GHz Wireless, Bluetooth 5.3 and USB-C are available for connection. Over 2.4 GHz and wired, the keyboard achieves a polling rate of 8000 Hz. In Bluetooth mode, it is 125 Hz. Up to three Bluetooth devices can be paired. N-Key Rollover is supported both wirelessly and wired. ZMK is used as firmware. The browser-based Keychron launcher can be used to configure key assignments, macros, shortcuts, lighting, firmware and other functions. macOS, Windows and Linux are supported.

Color Versions

The complete metal housing is made of 6063 aluminum. The material ensures high stability and durability in daily use. This variant comes in black and combines the dark aluminum housing with the characteristic Keychron look.

Aesthetic PC Backplate

The PC backplate has a cleanly executed and scratch-resistant surface. In addition to its technical function, it contributes to the tidy structure and characteristic look of the Q3 Ultra 8K.

660 Hours of Use on a Single Charge

The integrated lithium polymer battery has a capacity of 4000 mAh. With the lighting off, up to 660 hours of wireless use are possible. With RGB at the lowest brightness level, it is up to 200 hours. The keyboard can also be used while charging.

2.4 GHz & Bluetooth Connection

The Q3 Ultra 8K achieves a polling rate of 8000 Hz via the fast 2.4 GHz connection. This means that inputs are transmitted to the computer particularly frequently. Bluetooth 5.3 complements the equipment for devices where maximum speed is less important. Up to three devices can be paired via Bluetooth.

An Epic Core Inside the Keyboard

A powerful ARM-based microcontroller with 1 MB of flash memory takes over the processing of the inputs. Both in wired operation and over 2.4 GHz, 8000 Hz polling rate is available.

Keychron Silk POM Switch

In this variant, Keychron Silk POM Brown switches are installed. The stem and housing are made of POM, the switches are factory-lubricated and have tactile switching behavior.

• Operating force: 55 ± 15 gf
• Flow: 2.0 ± 0.4 mm
• Total travel: 4.0 ± 0.4 mm
• Switching behavior: tactile
• Service life: up to 50 million actuations
• Sound character: gentle

The Brown Switches are particularly suitable for users who want to feel the trigger point when typing. The tactile feedback gives every input a little more control, without the clear click of a clicky switch. This makes them feel pleasantly versatile for both typing and gaming.

Program with Keychron Launcher

The Keychron Launcher runs directly in the browser. Keys can be reassigned, macros can be created and shortcuts can be customized. In addition, lighting and firmware can be configured. A separate software installation is not necessary. Compatible browsers such as Chrome, Edge and Opera are supported.

Satisfying Keyboard Acoustics

Multiple damping layers within the cabinet reduce unwanted vibration and resonance. Together with the PC plate and the double-gasket construction, it creates a controlled, full sound instead of a hollow cabinet noise.

Double-Gasket Design

Silicone pads between the upper and lower case elements decouple the construction. This maintains some typing flexibility while reducing cabinet resonances.

Suitable for All Devices

The Q3 Ultra 8K supports macOS, Windows and Linux. A system switcher makes it easier to switch between Mac and Windows. Additional keycaps for both operating systems are included.

KSA Profile Double-Shot PBT Keycaps

The KSA Double-Shot PBT Keycaps have permanently incorporated legends and a durable surface. PBT is less susceptible to shiny wear than many ABS keycaps. The keycaps are not translucent.

Hot-Swappable

The hot-swap sockets allow the switches to be replaced without soldering. Most mechanical 3-pin and 5-pin MX switches are supported. This makes it easy to adjust the typing feel later – in case Brown should eventually give way to Red or Banana.

All New Screw-In PCB Stabilizers

Bolted PCB stabilizers increase the stability of large keys. Spacebar, Shift, Enter and Backspace move more controlled, with less lateral play.

Unlock Dynamic Backlit Control

The south-facing RGB lighting offers more than 22 lighting effects as well as static white lighting. The Keychron launcher can be used to customize effects and settings.

Per-Key RGB

With Per-Key RGB, the color of individual keys can be set separately. For example, important gaming keys can be visually highlighted or individual color schemes can be created.

Mix RGB

Mix RGB allows for different lighting zones, each with its own effects. This allows you to combine multiple lighting styles on the keyboard at the same time.
