“Beautiful service from yourselves, got updates at every point required. Product is amazing and arrived wrapped well. Only issue was the courier delivering the parcel by throwing it into the house rather than handing it in person. Already reviewed their poor…”

“I upgraded from the Q1 as I never really liked 75%. The weight, sound and feel of the Q3 are all amazing. Really good build quality. Money well spent.”
“I thought I had found exactly what I wanted and its great for what it is, but! This was advertised as an ANSI layout but what I received was an ISO layout board. The barebones board also states in the images that it comes with switch and keycap removal tools…”

Keychron K3 Max SE vs Q3: your questions
Yes, the K3 Max SE supports USB-C wired connection, and you can use it while the 1550mAh battery charges. The vendor states it works in wired mode alongside 2.4 GHz and Bluetooth 5.2 connectivity.
No, the Keychron Q3 is a wired-only keyboard. It connects via USB-C and does not have Bluetooth or 2.4 GHz wireless options, according to the specifications.
Yes, both keyboards feature hot-swappable PCBs. The K3 Max SE uses Keychron Milk POM low-profile switches, while the Q3 supports standard 3-pin and 5-pin MX mechanical switches, as noted by the manufacturer.
Both keyboards offer Mac and Windows support with system toggle switches and include extra Mac keycaps. The K3 Max SE is pre-configured with a Mac layout, and the Q3 also includes Mac keycaps in the box, making both suitable.
No, the K3 Max SE uses low-profile LSA double-shot PBT keycaps and low-profile switches. Standard Cherry MX keycaps and switches are not compatible due to the reduced height.
Yes, the Q3 is available in a fully assembled knob version with an aluminum rotary encoder. The knob is programmable through VIA for functions like volume or zoom, as described by Keychron.
The Keychron Q3 uses screw-in PCB stabilizers, which offer more stability and smoother performance. The K3 Max SE uses plate-mounted stabilizers, which are simpler but may feel less stable on space bars and shifts.
Both keyboards support QMK firmware and can be customized using Keychron Launcher web app. You can remap keys and create macros without installing software, using a compatible browser.
Yes, the K3 Max SE offers a 1000 Hz polling rate in 2.4 GHz and wired modes, along with N-key rollover. The manufacturer states this provides low latency suitable for competitive gaming.
The K3 Max SE weighs 566g, while the Q3 weighs 2000g for the fully assembled version. This makes the K3 Max SE over three times lighter and far more portable.
