“Worked perfectly, best keyboard I've ever owned. For one hour. After that all RGB turned off, and the main function of the keyboard (Typing), no longer works. I can't type with it, the web launcher doesn't detect it either, just don't waste your money.”

Keychron J2 HE vs Q0: your questions
No, the J2 HE is a wired-only keyboard. The metadata and vendor description only list Type-C wired connectivity. There is no Bluetooth or wireless mode available for this model.
Yes, the Q0 supports both QMK firmware and VIA via the Keychron Launcher web app. The vendor description confirms open-source QMK firmware for key remapping, macros, and shortcuts, and the Launcher web app is available for customization.
The J2 HE uses Keychron Ultra-fast Lime Magnetic Switches, which are Hall Effect switches. These use magnets to detect key presses and allow adjustable actuation points. They are pre-installed in the fully assembled version.
The Q0 is available with Gateron G Pro Red (linear), Blue (clicky), Brown (tactile), Keychron K Pro Banana (tactile), or as a barebones kit without switches. The fully assembled version includes pre-lubed Gateron G Pro switches.
Yes, the J2 HE is hot-swappable, but only with compatible Hall Effect magnetic switches. The vendor description notes that mechanical switches are not supported due to the different technology used.
The fully assembled Q0 comes with double-shot PBT keycaps in OSA profile. OSA is described as having a height similar to OEM profile with an SA-like spherical shape. The keycaps are not shine-through.
The J2 HE offers an 8000 Hz polling rate, with options to switch to 1000 Hz or 4000 Hz via the Launcher web app. The Q0 has a fixed 1000 Hz polling rate. The J2 HE's higher polling rate reduces input lag for gaming.

Yes, the J2 HE features significantly enhanced acoustic foams and a steel plate according to the vendor description. These are designed to provide responsive feedback and a more comfortable, quieter typing sound.
The Q0 uses a full CNC machined 6063 aluminum case. The vendor description highlights a multi-stage manufacturing process including polishing, anodizing, and sandblasting for a premium finish.
No, the J2 HE does not have a screen. The metadata lists 'Screen: No', confirming the absence of an integrated display on this keyboard.
The vendor description states that the J2 HE is compatible with Windows and macOS. No mention is made of Linux or other operating systems in the provided data.
