Comments on HMX Longjing S switches | Comments on HMX K01 switches |
The HMX Longjing S tactile switch is the successor of the Gateron Longjing tactile switches. Material-wise, these two switches don't differ much, but HMX's light tactile molds make them feel and sound drastically different. Longjing S tactile switch is similar to the HMX K01 tactile switch, which delivers a mid-clacky bottom-out sound; The tactile bump is on the smaller side and similar in size to the Cherry Brown switches – Unikeys. If you're a fan of HMX K01, you'll like these too… primarily because they're pretty much a recolor. Made with a PA66 top/bottom paired with a POM stem. The tactile bump is very light with these, similar to what you would feel with Cherry Browns. Sound wise, very similar if not identical to K01. A clean, crisp clacky sound profile that isn't too loud. No ping, crunching, or any other weird noises. These are some of the best light tactiles HMX offers. Right up there with Yamatake and Valerians. I would highly recommend! – @keyboard_dad. The HMX LongJing Tea S Tactile Switch is the next evolution of the classic Gateron Longjing tactile switches. With HMX’s new tactile molds give the Longjing S a noticeably different feel and sound – LumeKeebs. | The HMX K01 tactile switch is HMX's first-ever light-tactile switch to be released. The smaller tactile bump creates a comfortable typing feel with moderate tactile feedback, which is optimal for long-term typing duty and daily use. Technically, these are a long pole switch, but the stem pole is not extended by much; A 3.8mm travel distance makes the bottom out solid but not abrupt. Material-wise, we went with the classic non-modified PA66 housing and POM stem for the K01 light tactile switch; Such material choice maintains the classic HMX clack and doesn't make the switch sound overly loud and high-pitched. They sound clean and crisp overall, and I don't have to tell you how pleasant they will sound on your keyboard. The top housing comes with a matted texture just like the HMX Sonja and Sonja HC switches to create a grainy, scratchy feeling during typing. Important to note: When buying X90 or more switches, they will come in our brand-new switch container – Unikeys. |
