BSUN Maple Sugar switches are overall thocky (or deep and loud sounding). The S3 material, despite its novel code name, is a POM blend plastic. The POM top housing makes sure the top-out doesn't sound too sharp or loud and is still smooth enough when paired with an S3 stem. Because both the top housing and the stem are made of POM material, you can hear a very slight scratch sound when you put the switch right next to your ears. You won't be able to feel the scratch, however. The modified nylon bottom housing is the key ingredient here as it livens up the overall sound signature to make it more poppy.
