Comments on HMX Blue Topaz switches | Comments on Keygeek Roxy switches |
Made by HMX. Blue Semi-transparent Top. Designed by Mage Studio. PC top housing, LY stem, P4 bottom housing for refined sound. Specially molded top minimizes loose top-out noise. Quieter than P3 but not as deep-sounding. Similar sound profile to HMX Hyacinth V2 – Candykeys. | Clacky is no longer a good word to describe how high-pitched and loud these switches are. For the Keygeek switches that use the P bottom housing, including Roxy, of course, I personally prefer using the word "metallic" to describe their sound profile. The transparent PC top housing not just looks beautiful with glitter, but it also makes the switch feel super smooth overall. It also helps with the top-out sound by making it brighter – Unikeys. |
