Comments on HMX Puppy switches | Comments on HMX Hydra switches |
A strong, well-tuned tactile with a warmer character. The bump is pronounced, but cleanly guided and not scratchy. Sound-wise, it leans more deep and thocky, setting it apart from many brighter HMX switches. A strong choice for anyone who wants noticeable feedback paired with a fuller, more pleasant sound – MonacoKeys. | The HMX Hydra tactile switch is designed by XLLAB and features a big almost D-shaped tactile bump similar to Retro J. It is an attempt to replicate the classic Gateron Type R's D-shaped bump, but with a touch of the signature HMX clacky sound profile and fantastic stem wobble control. Thanks to the P2 bottom housing, the Hydra switches are one of the clackiest HMX tactile switches so far – Unikeys. |
