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 would say the B400 is the more balanced, while the a4 is more v shaped regardless of what filter is used. To me, the a4's soundstage is flatter, with less depth than the b400's, but with more width than the b400. I love them both, but have definitely been using the b400's more than the a4's lately. They just have such an intoxicating and smooth signature, that plays most genres of music well.
It just looks nice, with the metallic internals and your lighting. It'll be more matched if the shell is metal and of the same colour, though. Psst...Brainwavz. Something something stainless steel body. B400 MKII? Future enhancement. Dat is definitely de wae.
