I have tried the browns, reds, and whites. I believe these switches are full PC housing and the sound they make is higher pitched and can be fairly loud. If you're looking for low pitched "thock" sounds, you'll want a different switch. Personally, I enjoy the sound and feel of the reds and the whites. I do not generally use tactile switches, and the brown switches didn't change my mind, however, someone that prefers tactiles might like them. I really felt and heard a pronounced bump which I found distracting and kind of unpleasant. It kind of felt like I was popping something with every keypress. That might be something that a tactile switch lover might be seeking, perhaps. I haven't tried doing any modifications to these switches, and they feel smooth enough out of the box.
