Still happy with my B3, but I've been wondering, is there anything in the price range with an even wider, roomier 3d soundstage? (The Havi are already quite good at that, but still far from full sized open headphones)
Imo the inexpensive Brainwavz R1 fulfills this criteria with a huge width and depth.
The downsides of it are that the resolution is clearly below the Havi's, instrument separation ist not as good as the Havi's, the Brainwavz has got a different tonality (V-shaped with loads of sub-bass) and the bass is kind of bloated. But in terms of soundstage size (depth and width) and soundstage authenticity it is awesome.
