Comments on Keygeek B1 switches | Comments on HMX Bad Sweetheart switches |
What if I tell you the Keygeek B1 switches are the clackiest switch so far on earth? The keygeek B1 linear switch is the first ever switch that uses a nylon bottom housing with 50% fiberglass added. The M4 strengthened POM stem and the N5 nylon bottom housing are born for one thing: To create the clackiest switch possible – Unikeys. | The Bad Sweetheart switch designed by Rena Lab is one of the deepest sounding HMX switches so far; Thanks to the T5 UPE blend stem, the spherical stem tip, and the new P4 bottom housing molding, they don't sound like your usual HMX type. The new P4 bottom housing comes with as less fiberglass as possible in order to eliminate the clacky tone from the sound profile. If you are a fan of deep and thocky sounding switches that are not muted, the Bad Sweetheart switches would be a great option – Unikeys. |
