What will you mostly use it for?
The K1 Pro is the clear choice for users who value customization, whether through hardware (hot-swap switches) or software (QMK/VIA), and for tasks like gaming or programming where its specified N-key rollover and programmability are assets.

For general office use, both are competent, leaving the decision to budget and preferred build feel.

“I really like this keyboard, particularly due to its ISO PT layout. For the next iteration, I suggest using a higher-quality plastic, as the keycaps feel a bit cheap. I would easily pay 20/30 EUR more if the keyboard felt more premium.”
“I bought this keyboard from Amazon and I thought I love it. A little over a year later (15ish months) the keyboard starts glitching like the shift key is stuck and would randomly type in ALL CAPS and add weird punctuations. The keyboard made my…”

“I realy like this keyboard. I feel is harder to make typos compared to the K3 v2. I decided to go with the K1 Pro instead of the K3 Pro and it's going to to take time to adjust to the new layout, but the feeling and shape of the keys is definitely better.”

Keychron B1 Pro vs K1 Pro: your questions
The K1 Pro generally offers a more premium typing experience with its double-shot PBT keycaps and aluminum frame. However, the B1 Pro uses similar low-profile switches and may be sufficient for those prioritizing a lighter, more budget-friendly option. User reviews for the K1 Pro specifically praise its typing feel.
The product metadata and description for the B1 Pro do not mention hot-swappable sockets. It is listed as a pre-built keyboard, suggesting the switches are not user-replaceable without soldering. The K1 Pro offers a dedicated hot-swappable version.
No. According to the connectivity metadata, the Keychron K1 Pro only supports Bluetooth and wired connections. The B1 Pro is the model that includes a 2.4 GHz wireless option alongside Bluetooth.
Yes. The K1 Pro uses low-profile double-shot PBT keycaps. Since it features a standard low-profile mechanical switch, you should be able to replace them with other compatible low-profile keycap sets.
The vendor description for the B1 Pro claims a battery life of up to 1200 hours. The K1 Pro has a larger 2000mAh battery, but its official runtime is not stated in the provided information. Actual battery life will depend on usage patterns like backlighting.
Potential caution is advised. A user review for the B1 Pro notes that fast typists may experience key rollover issues with certain multi-key sequences. The K1 Pro's specification explicitly lists N-key rollover for both wireless and wired modes.
Yes, but through a different method. The B1 Pro vendor description states it can be programmed using the Keychron Launcher web app for key remapping and macros. The K1 Pro adds the more advanced, open-source QMK and VIA support on top of the Launcher.
The B1 Pro case is made of plastic/ABS. The K1 Pro features a hybrid construction with an aluminum frame and ABS, giving it a more substantial and premium feel on the desk.
Both are highly compatible. Each offers a Mac layout with Windows support and includes keycaps for both systems. The K1 Pro's listing shows support for a wider array of specific ISO layouts (like German, UK, Nordic).
The product description does not list a wrist rest as included in the box. However, the vendor page shows compatible resin, wooden, and silicone palm rests available for separate purchase as add-ons.
Yes, both are marketed as suitable for Mac users. Their descriptions state they offer the same multimedia and function key functions as Apple keyboards and come with Mac-specific keycaps, while remaining fully compatible with Windows.
