Wow - really. How long did you own the 535's. personally I thought they were great earphones - just missing some extension on the highs, and the mids over-done a bit. Yes over-priced based on what you can buy now, but not back when they and the Westone's were the only decent triples on the market.
And the VSD3S? I have that - just haven't got around to reviewing it yet. Its good value for $40, but better than an SE535 - really? I wouldn't say they are any better than your average $100 earphone on today's market. The FiiO F9 skins them IMO, and its not at the level of the B400. In fact with the VSD3S there almost seems to be some coherency issues in the mid-range - definitely not overly engaging IMHO.
