Ok thanx guys, I will get more info about E80, I had E30 some time ago and was happy with them. And will take a listen to Dunu, GR07 and some gybrid T-Peos. Unfortunately A73 are too expensive($150), maybe later.
BTW I've never had an on-ear headphones and I wonder if they are good for me. What models the Havi B3P1 owners could advice me to try between up to $80 if I really like the sound-stage, overall non-V-shaped, smooth and deep sound signature and 3D-sound of Havi?
Pretty much for just below $80, you only have the Havi. Those are it's strongest points. The VSD3S has a big soundstage but more V-shaped and less 3D. Haven't heard the other budget king brands enough to do a comparison. Perhaps if you go a little higher you have the Trinity Delta? https://www.kickstarter.com/projects/157887895/trinity-audio-engineering-audiophile-grade-in-ear?ref=nav_search
