Woops, missed this..
Ei.3 has fun, v-shaped signature, but with slightly laidback feel. Its perfect for casual listening session. Considering your media is from youtube/facebook, this will suit you.
Better try the demo first, and hear which you like the most
. For me, my order of preference:
#1: FIBAE 2
#2: Ei.XX
#3: Ei.3
#4: FIBAE1
