Lots of posts today and I was not notified by mail, thanks so much for answering!
I've been browsing more info and reviews, considering I have to EQ on all of them, I decided to order the Sundara until I saw the weight. No one mentions it in their comments, but I know it will hurt my neck and maybe the headband will bother me (although the k702 I have weighs quite a bit less and despite me having hair, it hurts the top of my head).
I ended up buying the Fiio FT1 in hopes of being able to reduce the amount of bass it has, which is what made me discard it originally. I have only been able to locate stock on aliexpress in the light color, so I have ordered it from a store that seems to have a lot of good reviews. I hope all goes well because it doesn't seem to me to be the ideal platform for this type of gear.
