[Memory Foam] I use these on my Sylinx ear pieces, these are longer than the foam tips provided by Sylinx. The Sylinx tips would break seal occasionally during drills. The longer length of these tips have solved the problem.

[Black] Best foam on the market. Really pricey in small packs. But affordable in bulk.

[Memory Foam] These things help to keep earphones in your ear a lot better than stock tips and block way more noise making them a great upgrade. Highly recommended. Good quality as well!

[Black] I am using these on Seinnheiser Momentum3 True wireless earphones. They really increased isolation improving noise cancellation and sound. The bass really kicks now. They are a tight fit but still comfortable. I compared them to Comply tips and these were better at isolation and fit.

[Black] I purchased these ear pads for a pair of Koss Pro-dj200 headphones. They were a little hard to get on, but they fit fine. They are way more comfortable than the stock pads. The sound did not change at all. Good ear-pads Dekoni

[Memory Foam] I use these with Etymotic HF5 and ER4. After using the Red and Orange foams for a long while I decided to try the Black foams for a less tight fit and they are perfect. I suggest getting a sample pack and try each size for a few weeks for best fit especially for using long term... I sometimes have my earphones in for hours at a time.

[Black] Unlike the first reviewer, I found these earpads to be easy to install and they are firmly attached.The leather is very smooth and supple and feels luxurious. In my opinion these are a step up from the original Sony earpads.

[Black] My KEF M100 earbuds have very good clarity and detail, and they're a bit lightweight in the bass notes. As far as I can tell the chart is based upon which of their memory foam tips will fit snugly over the barrel of your earbuds (the part you stick in your ear). The M100s aren't listed on Dekoni's matching chart. I emailed to ask them which, if any, might fit the M100s. They replied within 24 hours that their Mercury tips should fit (4mm size hole). Using the small size tips in place of KEF's rubber tips I noticed right away that the earbuds have a snugger fit and they don't work loose or fall out while I'm out for a daily long walk. They are also comfortable; just don't try to shove them too far into your ears - haha. Two more good points are that they help block out a little more external traffic noise and they have improved the bass response that I hear when listening to music. The KEFs are never going to sound big and punchy in the bass, but they are definitely improved when using these little memory foam tips. Haven't tried the medium or large size tips yet. Maybe they'll be even better, or maybe they'll be too big for my ear canal. The idea is to experiment with all three and find the best ones for my ears. Then, maybe later, I can order a pack of just the one size that works best for me. No two people have exactly the same ears, so you must experiment to see what will work for you.

[Black] The pads on my ATH-M50x started to flake after some months of use. I typically tend to use them for extended periods with breaks in-between. To be fair, you're supposed to give them a cleaning after use so that may be the cause of the flaking over time.

Besides that, they got to a point where the headphones felt unbearable and quite fatiguing due to the pads getting too soft, making the headphones clamp on harder than before. After doing some research, the other alternatives--although comfortable--were too thick (which changes the sound a bit) and cost a little too much for what they were imho. I wanted to have pads that had comfort as well as allowed the sound to be close to the original.

Eventually I heard about Dekoni. Went over some reviews and heard good feedback. What made me pull the trigger on these were the size and cost. They came in very neat and simple packaging. No instructions but I assumed that's because it's such a simple process, there was no need to include any. They should still provide it because what may be simple for one is a challenge for another.

After removing the old ones, then giving the shell a cleaning with some isopropyl alcohol, these went on easily. You just have to be gentle and take your time. You'll have to stretch it a little to fit completely but that's not an issue.

They feel way better than the ones that came with the M50 and I honestly couldn't tell the difference in sound between the two. This is exactly what I was looking for. It's been over a couple of weeks since they've been in use and I don't have any issues or regrets so far. Would definitely recommend.
