Key Takeaways
1. Keychron K9 Max features new Milk POM switches, available in three types: Red, Brown, and Banana, offering a smooth key feel.
2. The K9 Max retains a compact 60% layout with 61 keys and includes high-quality double-shot PBT keycaps and an aluminum top plate.
3. Strong connectivity options include 2.4 GHz, Bluetooth 5.2, and wired USB-C, with a battery life of up to 73 hours without backlighting.
4. The keyboard includes customizable RGB lighting, key remapping, and macro creation through the Keychron Launcher, which is QMK compatible.
5. The K9 Max is available in both non-hot-swap ($99.99) and hot-swap ($109.99) versions, with the hot-swap option providing better durability.
Keychron offers a wide range of low-profile mechanical keyboards. While they feature a simple design, versatile connection options, and good build quality, our review of the K15 Max showed that the Gateron Low-Profile 2.0 mechanical switches didn’t quite meet expectations. This became even clearer when Lofree introduced the Flow series, which used full-POM switches that were much smoother, more consistent, and overall better when we evaluated the Flow Lite.
New Developments with the K9 Max
Recently, Keychron announced the Keychron K9 Max, aiming to rival the POM keyboards with its Milk POM switches, which come standard in this model. The K9 Max offers both a non-hot-swap version for $99.99 and a hot-swap option for $109.99. If you’re looking for durability, the hot-swap variant is definitely the better investment.
Key Features of the K9 Max
The standout feature of the Keychron K9 Max is its new Milk POM switches, available in three types: Red (45 gf linear), Brown (50 gf tactile), and Banana (57 gf sharp tactile). All switches feature a POM housing and stem, providing smooth feel throughout the key travel. The total key travel is slightly extended to 3.1 mm, with the linear switch activating at 1.7 mm, and both tactile versions also at 1.7 mm. Weighing just 426 g, this keyboard is a great choice for those who are always on the go.
Design and Layout
The K9 Max sticks to the familiar design formula used in Keychron’s low-profile keyboards, featuring a compact 60% layout with 61 keys. It comes with an ABS plastic case, an aluminum top plate, and a floating keycap design. While this design might feel a bit outdated, it fits well within Keychron’s product line and is subtle enough for a professional environment, which appears to be the intended audience for K-series low-profile keyboards. The K9 Max stands at a height of 7.9 mm, which is nearly 5 mm shorter than the Iqunix Magi65 Pro, a product we recently reviewed, priced starting at $139.99 on Amazon.
Strong Points and Connectivity
By reusing a successful design, the Keychron K9 Max retains all the strong attributes we expect from Keychron keyboards, including hardware OS and connectivity toggles, flip-out feet for better ergonomics, internal sound dampening foam, and high-quality double-shot PBT keycaps in the KSA (Keychron Spherical Angled) profile.
Battery Life and Backlighting
Connectivity options for the K9 Max include 2.4 GHz with 1 kHz polling for minimal latency, Bluetooth 5.2 with 120 Hz polling, and a wired connection using a detachable USB-C cable. The K9 Max is equipped with a 1,550 mAh battery, which Keychron claims can provide about 73 hours of use without backlighting and 42 hours with the backlight set to its lowest brightness. The backlighting is RGB and positioned north-facing, which should make it easy to find compatible shine-through keycaps.
Customization and Software
RGB lighting, key remapping, and macro creation can be controlled via the Keychron Launcher, which is a beneficial tool for Keychron users. It enhances the versatility of the 60% layout with features like Mod Tap and layer support. Based on our previous experiences, the Launcher has always performed well, and the Keychron K9 Max is also QMK compatible, giving users the option to use open-source software or VIA for customization.
