Comments on MMD Vivian switches | Comments on HMX Hibiscus switches |
MMD Vivian linear switch delivers a satisfying thocky sound profile. The switch features a modified UPE stem that enhances durability. Its top housing is constructed from PA12, while the bottom housing uses modified PUM – Lume Keebs. | 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. |
