I use the triple flange tips provided by Westone and also the ones from Shure, and they fit pretty well and insert deep enough for good isolation. I want to know if these ones from ebay would be able to have the same depth of insertion as the Westone or Shure ones, because it does look like the bottom end has been trimmed. I bought similar tips from earplugstore before and those literally provided zero isolation due to the trimmed down tube. So are these any better? http://www.ebay.com/itm/Medium-Triple-Flange-Ear-Buds-Tips-Cushions-Westone-In-Ear-Earphones-Clear-/200681093903?pt=Other_MP3_Player_Accessories&hash=item2eb9867b0f
 
I also found these, which does seem to have a longer tube. http://www.ebay.com/itm/earbud-replacement-triple-flange-/150685907018?pt=Other_MP3_Player_Accessories&hash=item231594784a
Might try getting these instead...

Used single/double/triple flange.. I'd say as long as they're silicon, the largest difference between them is sound isolation. And triple flange can be uncomfortable at times.
 
If you're going to upgrade your tips, go for super tips (gel) or foam tips from Shure or Comply.
