Comments on MMD Princess Linear Ultra switches | Comments on Novaris Studio x Keybay Her Heart 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. | The inspiration for Her Heart comes from the quiet, futuristic romance of the film Her — a sweetness that feels close, yet gently distant. We continued the signature color language of the Her series, blending soft pink tones with a misty translucent finish to create a look that feels both dreamy and honest — just like modern relationships: warm yet independent, intimate yet respectful of boundaries. Sound: soft, deep thock, bottom-out and return sound clean and consistent — like a freshly bathed cat: fluffy, gentle, and quietly healing. Feel: Silky smooth. Warm and refined. Solid bottom-out without harshness. Clear key-press confirmation without wobble – keybay.tech. |
