Comments on MMD Princess Linear Ultra switches | Comments on HMX Hibiscus switches |
The MMD Princess Ultra Thock switches are the latest variant of the MMD Princess Series and were specially designed and manufactured for the Bridge75 keyboard. As usual with MMD Princess, the switches type very well and have an even deeper sound than the Princess V4 – Monacokeys. Produced by the latest mold, the new Princess Ultra switch offers smoother and more consistent typing feedback. We've also improved the factory lubrication and bottom material, elevating the "thock" sound profile to a new level – qwertyqop. | HMX Hibiscus switches come with a T3 stem, PA12 top housing, and PA66 bottom housing. Spec-wise, it is a bit similar to the Canglan V2 and EVA switches which are one of the deepest and most thocky HMX switches. We are not sure what the T3 stem is made of nor its formula, but based on the sound comparison to Canglan V2 and EVA, the T3 stem makes them sound a bit deeper and quieter than both Canglan V2 and EVA switches. In the meantime, they still come with that signature HMX clack and solid bottom out sound – Unikeys. |
