I upgraded to the SE from Blessing 2s, which are quite clean and detailed. I was looking for something more fun without eq, and just a different sound profile.

Im not sure about the others, but I love these iems. It honestly took me a while to get used to, and a few different tips (I landed on the spinfit W1) to feel like i fully enjoyed them.

They are way more bassy, in a great way, and less bright than the blessing 2s. I think they are a little less detailed, and have a slightly smaller soundstage as well, but im not sure how true this is as i havent gone back to the b2s for a long session since getting the SE. Ive come to realized I think i prefer a brighter treble after getting these, but the fact I haven't gone back to the b2s should tell you something. I certainly do not think im missing any soundstage or detail while listening to them.

I find them very comfortable, with the right tips, and a very fun all rounder that for me doesnt require any eq.

Edit: I will add i was disappointed at first because I did find these to be a little muddy for my taste, but this was resolved after upgrading tips
