Pick the Keychron J2 HE if wired use is acceptable and you prioritize 8000 Hz polling with adjustable-actuation Hall Effect switches.

Its extra weight is a clear trade-off if you plan to carry the keyboard often.

What will you mostly use it for?
The J2 HE takes the gaming pick on its higher wired polling rate and Hall Effect switches. The Q2 Pro has the edge for office work, programming, modding, and content creation, where wireless connections, switch choices, or the programmable knob are relevant. Travel is a trade-off: the Q2 Pro can run over Bluetooth, while the J2 HE is substantially lighter but requires a cable. Choose based on whether wired speed or wireless and build flexibility matters more in your setup.
Pick the Keychron J2 HE
- The J2 HE has an 8000 Hz polling rate in wired mode, compared with the Q2 Pro's 1000 Hz wired rate.
- The J2 HE uses Hall Effect magnetic switches with adjustable actuation points.
- The Q2 Pro supports N-key rollover in both wired and wireless modes.

“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.”

“I purchased Q2 keyboard two weeks ago. It was sent from ShenZhen, China by DHL. Be careful you have to pay import custom tax. The keyboard is good quality. I am just surprise, after discount it is the same price as in Amazon. thanks.”

Keychron J2 HE vs Q2 Pro: your questions
The J2 HE has an 8000 Hz polling rate in wired mode, while the Q2 Pro lists 1000 Hz in wired mode. The Q2 Pro also supports N-key rollover in wired and wireless modes, so consider that feature alongside the J2 HE's higher polling rate.
No, the J2 HE is listed as wired only and uses a Type-C connection. The Q2 Pro supports both Bluetooth and Type-C wired connections.
Yes, Keychron says the Q2 Pro can connect wirelessly to up to three devices over Bluetooth, and it also supports a Type-C wired connection. Its battery is listed as 4000 mAh, with up to 300 hours of Bluetooth working time when the backlight is off.
The J2 HE weighs 780 g, while the Q2 Pro weighs 1489 g in its fully assembled version. The J2 HE is the lighter option, but it does not offer the Q2 Pro's Bluetooth connection.
The J2 HE uses Keychron Ultra-fast Lime magnetic Hall Effect switches, with adjustable actuation points described by Keychron. The Q2 Pro uses mechanical Keychron K Pro switches in fully assembled options, or can be purchased barebone without switches.
Both keyboards list hot-swappable switches. Keychron specifies that the J2 HE takes compatible Hall Effect magnetic switches, while the Q2 Pro supports most 3-pin and 5-pin MX-style mechanical switches.
Both list QMK and VIA support, and both are hot-swappable. The Q2 Pro offers a barebone version and compatibility with most 3-pin and 5-pin MX-style switches, while the J2 HE uses compatible Hall Effect switches.
The Q2 Pro supports a programmable knob, and Keychron describes assigning it functions such as zooming, volume, or brush size. The J2 HE's listed features do not include a knob.
The Q2 Pro has a full CNC-machined aluminum case and a polycarbonate plate. The J2 HE has a plastic case and a steel plate, so the material choice is between the Q2 Pro's aluminum construction and the J2 HE's lighter listed weight.
Both keyboards list QMK and VIA support in their metadata. Keychron's J2 HE description discusses its Launcher web app, while the Q2 Pro description names QMK firmware and the Launcher web app for remapping and macros.
Keychron lists the Q2 Pro as compatible with macOS, Windows, and Linux, and says the fully assembled version includes Mac and Windows keycaps. The J2 HE vendor description lists Windows and macOS compatibility.
Keychron describes the fully assembled Q2 Pro's KSA double-shot PBT keycaps as not shine-through. The keyboard has south-facing RGB lighting, while the J2 HE uses north-facing RGB and Cherry-profile double-shot PBT keycaps.
