Knife Lab Dolphins75 vs Lofree DOT Liquid Foundation: your questions
No, the Dolphins75 is sold as a DIY kit or barebones unit. According to the vendor page, it does not include switches or keycaps. You must purchase these separately to build a functioning keyboard.
Yes, the manufacturer lists Mac support among its features. It offers triple-mode connectivity, so you can connect it to a Mac via Bluetooth, the 2.4GHz dongle, or the included USB-C cable.
The Lofree DOT Liquid Foundation may have an advantage for quiet typing out of the box. It comes pre-built with sound-dampening Poron and IXPE foam, and its vendor description emphasizes a relatively quiet performance. The Dolphins75's sound will depend entirely on the switches and keycaps you install.
Yes, both keyboards feature hot-swappable PCBs. This allows you to change mechanical switches without any soldering required. The Lofree comes with Gateron Foundation switches installed.
The Knife Lab Dolphins75 uses a full CNC 6063 aluminum case, while the Lofree DOT Liquid Foundation uses an ABS plastic case. Aluminum typically provides a more premium, dense feel and sound profile.
The product specifications do not mention adjustable feet. The vendor description notes the included silicone feet are color-matched, but it does not state they are adjustable or removable.
The Lofree DOT Liquid Foundation is significantly more portable. It weighs 810g compared to the Dolphins75's 2400g, and its wireless functionality means you don't need to pack or manage a cable during use.
Yes. The Dolphins75 supports VIA, which is a popular, easy-to-use graphical software for remapping keys, creating layers, and assigning macros without needing to flash firmware manually.
The Lofree DOT Liquid Foundation uses a non-standard 75% layout. Customer reviews note it has a 1.75u Enter key, a 1.75u left Shift, and a bottom row with all 1u modifier keys alongside a 6u spacebar. This may limit compatibility with some aftermarket keycap sets.
Yes, both the Knife Lab Dolphins75 and the Lofree DOT Liquid Foundation are listed as using a gasket mount structure. This design aims to provide a softer, more consistent typing feel by isolating the plate and PCB from the case with dampening materials.
The Lofree DOT Liquid Foundation is equipped with a 4000mAh battery. The manufacturer does not provide an estimated battery life, as it will vary significantly based on usage patterns and whether the RGB backlighting is enabled.
According to the vendor description, the box includes the keyboard, a cleaning brush, a Type-C cable, a 2.4GHz wireless dongle, and a user manual. It is a complete, pre-built package.
