Keychron B35 vs V4 MaxCompact Layout vs High-End Customization

Only the Keychron B35 has a built-in number pad. It uses a 96% layout that integrates the numpad, arrow keys, and navigation cluster into a compact design. The V4 Max is a 60% keyboard, so a numpad would require using a separate keypad or accessing numbers via a function layer.

No, the Keychron B35 is not hot-swappable according to its specifications. Its switches are soldered to the PCB. If you want to easily change switches, the Keychron V4 Max features hot-swappable sockets compatible with 3-pin and 5-pin MX-style switches.

The B35 has an 800mAh battery with a claimed wireless working time of up to 320 hours with backlighting off. The V4 Max has a larger 4000mAh battery, offering up to 190 hours with RGB off, or up to 100 hours with RGB at its lowest brightness, as per Keychron's lab tests.

Both keyboards are compatible with macOS and Windows systems. Each includes a physical toggle switch to change between operating systems. The V4 Max also includes an extra set of keycaps for Mac-specific legends in its fully assembled version.

Yes, the Keychron V4 Max supports Bluetooth 5.1 connectivity according to its specifications, allowing you to connect to up to three devices. It also features a 2.4 GHz wireless connection with a 1000 Hz polling rate and a wired USB-C mode.

A gasket mount is a design where the plate holding the switches is suspended on soft gaskets within the case to reduce vibration and create a softer typing feel. The Keychron V4 Max uses a gasket mount design with a polycarbonate plate. The B35 does not use this mounting style.

Yes, both keyboards support key remapping via the Keychron Launcher web app. The V4 Max offers significantly deeper customization through its support for open-source QMK and VIA firmware, allowing for advanced macros and layer programming directly on the keyboard's hardware.

The Keychron B35 is marketed for silent typing, featuring a scissor mechanism and pre-lubed keys designed for a quiet experience. The V4 Max includes sound-dampening foam and a gasket mount to reduce acoustic resonance, but its mechanical switches will generally be louder than the B35's scissor switches.

The Keychron B35 uses ABS plastic keycaps. The Keychron V4 Max (fully assembled version) uses double-shot PBT keycaps in an OSA profile. PBT is generally more resistant to shine and wear compared to ABS.

The Keychron V4 Max is available as both a fully assembled keyboard and a barebones kit, which excludes switches and keycaps. The Keychron B35 is only sold as a pre-built keyboard and is not offered in a barebones configuration.

Neither keyboard includes a wrist rest in the standard box. However, the vendor page for the V4 Max shows a silicone palm rest as a frequently bought together item, indicating compatible accessories are sold separately.

Both keyboards offer a 1000 Hz polling rate in their 2.4 GHz wireless and wired modes, which is suitable for gaming. The V4 Max may have an edge due to its more powerful ARM Cortex-M4 MCU and N-key rollover support in all modes.
