120Pcs Clear Rubber O-Ring Keyboard, O-Rings Keycaps, Switch Dampeners Keycap, for Cherry MX Key Switch Keyboards Dampers,Blue

I recently installed the ThreeBulls 120-pcs Clear Rubber O-Rings on my mechanical keyboard and they’ve made a noticeable difference. The set includes enough rings to dampen all my keycaps, and the transparent design means you don’t lose the look of your world-showing RGB lighting. After installing them, typing feels smoother, quieter, and less “pingy” — the hollow sound under heavy keypresses is significantly reduced, which has been great for shared spaces or when gaming late at night. Installation was straightforward: I popped off each keycap, placed an O-ring around the stem, reinstalled the cap, and moved on. Because the rings are clear and thin, they barely change key travel but just enough to soften the bottom out. I found that my fingers felt less jarred during long typing sessions, and the sound profile shifted from a higher-pitched “klack” to a more muted, refined “thock”. For the price, getting 120 rings is generous and gives you extras in case you decide to adjust or replace later. The build quality held up during multiple days of use — no rings popped out, and none became loose or shifted underneath caps. They also didn’t interfere with the fit or stability of the keycaps. My wrist rest might get more attention than ever because my desk is quieter now. If you're looking for a simple, budget-friendly way to upgrade your mechanical keyboard’s acoustic profile and typing feel without changing switches, this O-ring set is an easy win. For value, performance, and usability, it easily earns five stars in my book.

These significantly reduced noise on my mechanical keyboard! It's not silent, but it's MUCH quieter now and doesn't bother my coworkers!

Worked fine to quiet the Keychron down a bit. Not as much as I would have liked, but it was worth it.

I have a RedDragon Horus K618 wireless keyboard w/brown switches, and these O-rings certainly reduced the sound! However the sound is less clicky, more scratchy and the keycaps are slightly higher than before (maybe 0.5mm)...either way, it is a cheap improvement! The keys are slightly mushier now, but overall these O-rings work fine! I would certainly prefer to replace the keyswitches to a quieter switch, but this is a good-enough alternative. There are enough O-rings in the 120 pack for a full-size keyboard, I only have the O-rings placed on the MX switch stem, not the stabilizers, and I've still got plenty O-rings remaining.

Quality of these are great, easy to use, and they make the switches feel better, they function about the same as always, just overall better feel to it. The noise level thought doesn't change all that well unless you have about 2 or 3 of these on the key. Overall love the product. I would recommend buying atleast 2 of these so that you can do so.

Works, but you can find this exact same product at a lower price on other listings.

Fits more snug than the o-rings that came with the plugs. I was loosing them all the time. G915 - Tried to place a few of these to reduce the notorious rattle. Although the rattle was minimized by 70% the size of these o-rings were too small. The o-rings hold so long as the legs on the keycaps are strong enough to support the o-rings in place. After 48 hours, I've had to remove a few o-rings from keys that popped off and showed signs of weakened connections. I tested it so you don't have to.

I'm putting these on a Logitech G512SE with the "Clicky" switches - similar to Cherry MX Blues, and note that it's important to get clear o-rings if you have illuminated keys because the o-ring does overlap with the key letter/number cutouts on this specific keyboard. While they don't block the key light, you can see a faint outline and different transparency of the o-ring through the letter cutouts. While the out-of-the-box typing experience was fine, adding these o-rings significantly dampened the "clack" sound of the key plastic bottoming out on the switch housing, to the point where I can only hear the sound of the switch being actuated rather than the combination of both the switch click and the key bottoming out (with the larger keys being the exception). Instead of the usual hollow bouncing of plastic, I now only hear the much quieter click of the key switch on the small keys. It still dampens the large keys (space bar, shift, enter etc.) but it's not as dramatic of a sound difference compared to the small letter keys. Just on the sound dampening front, the o-rings do the job well and are a winner. As noted by another reviewer, due to their thickness (which is about 1.8mm thick) they have roughly halved key travel. If you like your key travel distance, I would stay away from these and find o-rings with a smaller profile. But for me, I've always had an issue with the key travel being too deep so these were perfect. Because of shorter travel, I can really capitalize on the short actuation distance (distance for key press to register), making typing a lot easier, faster, and smoother. On top of all that, the o-rings have fully stabilized the keys whereas before, some of the keys could be tilted or wiggled about depending on the angle the press was coming from and they tended to be very "bouncy" which also has been completely negated by the o-rings. Overall, these o-rings were the perfect thickness to both noticeably quiet down overall typing noise and allow for adequate key travel on my specific keyboard. They also completely stabilized the keys resulting in a much more satisfying, solid, and smoother typing experience. These are a very affordable and necessary mod for any mechanical keyboard.
