[0.39" / 10 mm] 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!

[0.39" / 10 mm] Recently received these, fit very nicely in ears, super comfortable, lightweight. Audio is awesome for acoustic guitar and vocals.
Super happy with them !

[0.2 lb] Does exactly what it's supposed to do. And it worked with my 64 Audio CIEM's when I had an emergency cable issue. Good to know that these 2 pin cables are mostly interchangeable.

[0.2 lb] My wife is enjoying her new pair of cans. Thank you all for processing and shipping my order out so fast! We received them on Sunday. This was barely 3 days from when I placed it.

[0.41" / 10.5 mm] Tips work well. I find they have a slightly brighter sound than the foam tips, and the silicone lasts a lot longer than the foam.


My only complaint is that they sometimes come off a bit more easily than I'd like, popping off randomly and occasionally getting lost.

[0.41" / 10.5 mm] Best foam on the market. Really pricey in small packs. But affordable in bulk.

[0.41" / 10.5 mm] I have been using Westone in-ears for over a decade and I have loved all three pairs I owned. My first pair of UM2's lasted 10 years before I stepped on one of them, I tried gluing them back together but decided I might as well buy new ones. My second pair were UM Pro 30s and they have been going strong for 4 years.


I bought this pair of Pro X20s for my wife, but I have been using them the past two weeks. I cannot tell any sound difference between these X20s and the 30s I have, but I will also note that I use them for drumming and haven't listened to them back to back. The biggest difference I have noticed is how light the wire is on these X20s. It is so light and flexible, I can barely tell it is there. When I put them on, I cannot feel the wire at all. Very different than the thick, black, twisted wire on the old UM2 and 30s I have.


One last thing I have noticed over the years - Westone in-ears require significantly less volume than any other in-ears I have seen or tried. Before I plug them in to a foreign sound source, I always cut the volume at least 75% from what the last in-ears required. I've also mistakenly blasted full volume sound through both pairs of my older UM2s and 30s without damaging them whatsoever.


Definitely worth the price! Go with Westone, you won't regret it.

[0.39" / 10 mm] Super clear, well made, low profile and worth every penny.

[0.2 lb] 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.

[0.39" / 10 mm] 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.
