Funny you should say that because the bass isn't in anyway rumbling to my ears.looks like we have different preference. i prefer solid punchy bass instead of the rumbling kind, and also sparkly highs. i have those aet06 as well. i use them with fd5 for ultimate bass. now this reminds me to try the azla on the fd5
update: tried them on fd5, bass is good but still prefer aet06 on them, mid is more pronouced and fixes it's v-shaped signature
I do like tight base & good spacious mids but not to sparkling on the treble. This is what I get with the asla sednaearfit & aet06 tips.
It also depends on what we listen to aswell.
