Many years ago I bought Atrio M5 and I loved them for their. I also tried a couple of closed headphones and liked them for their soundstage & durability. Now I'm looking to combine all those into an IEM. I would accept closed headphones but it seems all of them require an amp, and I already have too many things to manage.
I'm still researching but possible options? My price range is listed but ignore if you feel it's applicable.
