Yeah I tried a bunch of tips but setlled on the white core SpintFits from my Co-Donguri and it was the best sound though the tip was slightly loose on the nozzle. I found my Lyra II box and the SpinFits in their, grab the medium is size Grey outer/Dark Red core and it fits even better in my ear and doesn't fall off the nozzle while providing the same sound.I havent tried the spinfits on my b400 yet, I'll have to since I found that stage depth was about equal but width was better on the Lz a4.
