Yunzii AL75 vs B75: your questions
The Yunzii AL75 uses a CNC aluminum case which gives it a more premium and durable feel compared to the plastic construction of the B75. The B75 still uses a gasket mount structure with multi-layer padding for a soft typing feel, but the AL75's metal chassis is generally considered higher end.
Yes, both the Yunzii AL75 and Yunzii B75 are hot-swappable and accept both 3-pin and 5-pin mechanical switches. This allows you to change switches without soldering to customize the typing feel and sound.
No, the Yunzii B75 is a wired-only keyboard that connects via USB-C. It does not have a battery and does not support Bluetooth or 2.4 GHz wireless, unlike the AL75 which offers tri-mode connectivity.
The Yunzii AL75 is better for travel because it supports wireless connections via Bluetooth or 2.4 GHz and has a 6000mAh battery for cord-free use. However, the B75 is much lighter at about 797g compared to the AL75's 1410g, so it is physically easier to carry in a bag if a wired connection is acceptable.
Only the Yunzii B75 includes a multi-function knob which can be used to adjust backlight brightness and device volume. The Yunzii AL75 does not have a knob and relies on key combinations or software for those adjustments.
Both keyboards are available with clicky, linear, and tactile switch options. Specific choices include the YUNZII Blue Grey Tactile Switch and the YUNZII Cocoa Cream V2 Linear Switch for the AL75, while the B75 adds the YUNZII Milk V2 Linear Switch as an option.
Yes, both the Yunzii AL75 and Yunzii B75 come with double-shot PBT keycaps in a Cherry profile which are more durable and resistant to shine than ABS keycaps. The B75 also offers side-printed and front-transparent legend variants.
The Yunzii AL75 is the only wireless option here with a 6000mAh battery. The vendor states it offers over 10 days of usage on a single charge with RGB off. The B75 has no battery and must remain plugged in.
Both keyboards feature south-facing RGB LEDs and custom software for Windows that allows you to design new RGB effects and set per-key lighting. The B75 vendor also mentions over 20 dynamic RGB effects available out of the box.
The Yunzii B75 is priced lower than the AL75, making it a strong choice for buyers who want a gasket-mounted, hot-swappable keyboard with a knob at a more accessible price. The AL75 costs more but adds an aluminum case and wireless capabilities.
Yes, both the Yunzii AL75 and Yunzii B75 include Mac/Win support as noted in their extra features. The AL75 has a physical toggle on the top for switching between operating systems, while the B75 uses software or key combinations.
The Yunzii AL75 weighs approximately 1410 grams due to its CNC aluminum case, while the Yunzii B75 weighs about 797.5 grams because it uses a plastic case. This makes the B75 significantly lighter and easier to move or store.
