Sorry, haven't tried the VSD3S, Havi B3, or the Vivo. I would throw in the UE600 at $50 as a good example of balanced, non-fatiguing sound. That sounds like a TDK BA200 to me. I compared it to the RE-400 here: http://theheadphonelist.com/headphone_review/tdk-ba200/ . I believe the BA200 has officially been discontinued but you can still find them on eBay and such. Another option is the Sony MDR-7550, but the BA200 is a better match IMO.
