In my professional opinion, the ear tips designed for the IE900 provide exceptional comfort, making them ideal for extended listening sessions. While I do not subscribe to the notion that in-ear tips significantly enhance sound quality, my experience with these tips has led me to reconsider my stance.
These came up in tip discussion, so I had to try them out. A lot to like, unfortunately a bit annoying during active use.
These tips sound like Spiraldots, they have a diffuse sound presentation characteristic of widening bore tips. Not bad if you are going for a more natural sound field vs a focused sound field. The flanges are very thin, so they conform readily and apply minimal pressure.
My problem is with longer use. The flanges are uniformly thin, so they have no structural integrity when removing. They will fold up and invert, causing me to fiddle with them to fix them. Spiraldots get thicker at the nozzle, so when they are removed, they spring back into their normal shape every time, same with Velvets. I would rather not have to touch the tips with my hands of possible to avoid contamination while out and about.
They also make a small crinkling sound when moving around, not ideal. The material is probably too thin.
Fit well and good sonic performance
