Bad fitting sleeves don't stay in, slip out, leakage
By Chauncey from Portland, OR on January 12, 2010
What I was looking for: a slightly-less isolating sleeve for my UM-1's. The original foam sleeves are comfortable and awesome fitting/sounding, but can block out TOO much sound for some situations requiring interaction with others, plus insertion/removal is an ordeal for casual listening on errands. Foam also also get kind of unsightly with use and wear out pretty quickly. Unfortunately, these silicone replacements were not the answer - they didn't grip any better than stock iPod buds. and the sound was even worse because of the poor seal. I'm going back to foam.
Pros:
Easy to clean, durable, cheap per pair.
Cons:
Poor fit, meaning they fall out easily don't seal properly so yield a poor sound, particularly in the bass.
Merchant Response:
Keep in mind eartips are just like shoes. What works for some will not work for others as we are basically trying to match our ear canal anatomy with one of the eartips size and material.
Most Comfortable for Me
By Douglas McMane from CT on October 11, 2009
Best, most comfortable for me of the sleeves included in a starter pack for the Westone 3.
Pros:
Very comfortable for me.
Sound quality comes through great.
Cons:
Why not include Westone 3 in the list of earphones these fit?
I would recommend this item to a friend.
Merchant Response:
Thanks for the suggestion. We will do that! ;)

I got these for UM1s. They were exactly what I was looking for. Blocked out noise, comfortable and easy to pop in and out. Perfect for the UM1s.
Only one that works

I almost gave up. I tried all the foams, flanges, comply sleeves--all of them. Could not get a comfortable seal, and therefore no bass. These things work, and they're so comfortable you will forget they are there. If you use a device these will fit, they will get out of it everything that is gettable.
