No apparent problems just out of the mod... still, something might come up later when I listen.... At least there is nothing much in the headset that can generate resonances... I perhaps should line the inside of the cups with dense felt just to make sure.
The problem I had with previous open back / open baffle mods (including the stock configuration) was that all bass vanished. That's basically solved with this approach.
Strangely, the cups are now empty. I suppose a cupless design would be possible - perhaps even a benefit?
