## Overview

Captain O-Ring Rubber O-Ring Keyboard Switch Dampeners reduce key travel by 0.2mm to minimize noise and finger fatigue. Made from durable EPDM rubber, this 135-piece set includes a microfiber cleaning cloth and installs easily on mechanical keyboards to prevent bottoming out and loud key clacks, enhancing your typing experience with lasting durability.

## Description

Captain O-Ring Mechanical Keyboard Switch Dampeners install directly onto the stems of your keycaps to prevent harsh bottoming out. When keys strike the switch housing at full travel, they create the sharp, loud "clacking" sound common to nearly all mechanical keyboards. Installing these dampeners provides a built-in shock absorber beneath every key, resulting in a quieter, more uniform sound profile and reducing finger fatigue during extended work or gaming sessions. This makes them an essential upgrade for open offices, shared or home workspaces, and late-night gaming setups where loud, continuous keystrokes can distract colleagues or bother light sleepers at home. Choose Your Feel & Key-Travel Reduction (color coded for easy identification): Blue (0.4mm Reduction): Provides a thicker cushion for maximum noise reduction, softer bottoming out, and shorter keystrokes. Ideal for heavy typists looking to minimize finger shock. Red (0.2mm Reduction): Delivers a slimmer profile for typists who prefer minimal change to their standard key travel while still deadening the harsh plastic-on-plastic switch impact sound of their keyboard. Built to Last: Unlike conventional rubber, which dries out, cracks, and degrades over time and under repetitive impacts, these dampeners are molded from high-grade EPDM rubber for long-term elasticity and tear resistance. Quick & Easy Installation 1. Gently pull each keycap off of the keyboard. Slide one o-ring securely onto the stem beneath each keycap. Press the keycap firmly back onto the switch and enjoy! Full installation takes roughly 5 to 10 minutes and lasts the lifetime of your keyboard. What to Expect - 135x Keyboard Dampener O-Rings (sufficient for standard full-size 104/108-key layouts with extras/spares) - 1x Captain O-Ring Screen Cleaning Microfiber Cloth Packaged in a resealable, zip-top poly bag. Backed by a 1-year manufacturer warranty against defect from Captain O-Ring LLC. Proudly assembled in the USA!

Review: Works quite well, within reason. - I am pretty happy with the results of these on my MX Brown keyboards. There were actually enough rings in one package to do my whole Tenkeyless board, as well as most of another Tenkeyless board, but I'm buying another pack to finish that one off as well as put them on my Vortex POK3R 60% board. As others have said, this doesn't completely silence the keys, but it probably does cut down on the noise by about 30%, and adds a different, more pleasant (to me) tone that's less 'clack' and more 'thunk'. When I showed a co-worker (who sometimes complains about how loud my keyboard is) the difference on the keyboard I wasn't able to fully outfit, she agreed that it was quieter, and wasn't able to hear my typing nearly as much from across the room. It does change the feel of typing a little, as there is a little bit of dampening at the end of the keystroke, but I also don't mind that, and in a way it almost makes the keystroke feel more solid to me. I'm also not having issues getting used to any shorter activation, either in gaming or typing. In any case, I am pretty happy with these things and ordered a second set, as I mentioned before. I also like that they included a cleaning cloth, just because it's nice to have them.
Review: A bit quieter, but biggest difference is in the feel - I have a CoolerMaster QuickFire XT (blue switches) and reckoned my keys were a little bit noisy considering my housemates were awoken when I started my homework in the morning. I decided to go with these O-rings as I quite like the chiclet keyboards on some laptops and feel like I can type very fast with them, so these "fat" rings (as opposed to the red "thin" rings) should do the trick. Installation was simple, albeit a bit tedious. I don't have a keycap puller so I fashioned one from a paper clip. (You should do the same instead of paying $6.99.) I initially only installed the O-rings on the 26 "letter" keys because I wasn't sure if I'd like them or not. Of course, as soon as I hit the space or wanted a capital letter the difference (in noise and feel) was massive, so I ended up putting the o-rings on all the "main" keys too (shift, enter, backspace, alt, etc.). I quite like the difference. It is noticeably quieter, although most definitely not silent. I would say the sound level is reduced 30%. But the biggest difference is the feel, as the travel is much shorter and the keys "bounce back" at the bottom of the stroke - as a result, my typing speed went up about 12 wpm. Overall, would recommend especially if you are wanting a change in the feel as well as the sound, but if your intention is only to reduce noise, these may not be the best solution. Still, a good thing to try before buying a new keyboard with different switches, however.

### ⭐⭐⭐⭐ Read Before Buying! I bought the RED and BLUE versions to try and test them both.
*by N***S on November 12, 2016*

Just like me, you're probably wondering what these are, what they do, and do they really work. And even if they do, how well do they work? I bought both the red and blues from this business to try and test them out. I have not tried the slightly more expensive WASD ones yet so I cannot compare it to that brand. First off, the reds are supposed to be thinner then the blues. When I received them I actually notice that they're also wider too, strangely. I don't think this is an issue, however, as it seems to be working fine. It's only noticeable during installation because the reds are a lot easier to slide into the keys than the blue ones are because they're wider. In terms of real world performance, I installed both the red and blues on multiple keyboards: Cherry MX Browns, Cherry MX Blues, and Cherry MX Reds. Then I tried gaming and multiple type tests online with them to see what feels best for gaming and typing. I've decided the color band matches best with the Cherry MX colors: blue with my MX Blue Keyboard and red with my MX Red keyboard. I don't have any on the MX Browns because I like them the way it is and it feels weird with any of the rings installed. The red rings doesn't help reduce noise in my opinion. It's only shortens the key presses by a very small margin that is barely noticeable from the start, but is slightly more noticeable after prolong usage. I don't like them on the MX Blues because it doesn't help reduce the clicking at all and the travel is negligible. I prefer them on the MX Reds because I feel the MX Red have a lot of wasted key travel that the red rings will help improve performance and response time. At the same time, the MX Reds aren't that loud so the red rings will be perfect for it. Now with the blues, they're much more noticeable and effective at reducing the noise. On my MX Blue keyboard, it reduced the noise, on average, over 10-15dB each key I measured. It makes the MX Blues sound so much more smooth and quiet. The reduction in key travel with the blue rings are very apparent and noticeable as well. It improved my typing time by 10wpm on average because it reduces the delay between button presses. It doesn't take a lot of force to activate a key on the MX Blue keyboard and when you're typing fast, you end up pressing each button pretty hard, pressing the button all the way down. The blues rings reduce the wasted time of the extra key travel after you press the button so you can move on to the next letter. All the while greatly reducing the noise. Another thing I realize is when I use the blue rings with the MX Red keyboard, I often miss when I play game or type. It seems the reds don't have a good activation feedback so I'm always unsure if I've actually pressed the button enough. Sometimes I feel like the blues are too thick for the reds as it needs to be pressed down more, I'm not sure. Overall I like blue rings more than the reds and would definitely get them again for all my MX blue keyboards.
