Just to clarify a few statements, I live in the country on a quiet road, and listen to music in a thermally insulated (also blocks some sound), carpeted room with a large wooden door that blocks the rest. There is absolutely no background noise problem, as even though you hear outside noise clearly, that is due to the ears low noise floor, which is easily overcome. I was not planning to cover the backs of these headphones, that was a joke. Seriously, I know all about how the open back allows for a greater soundstage and airy sound. The $330 was in Australian dollars, which equates roughly to $270 US, with free shipping from a reputable source. Taking everything into account, including recommendations, I got these headphones, and they sound absolutely amazing. To be honest, I shed a tear first time listening to them. Got a Schiit Fulla DAC, which complements them perfectly. I admit, I enjoy bass, and even though these are open, the bass they recreate is amazingly linear and smooth. Better than anything I have previously heard. Their highs are also stunning, reducing all harsh noise from my beats knock-off headphones to interpretable notes and tones, which give the music just so much more personality, as highs are no longer truly cringeworthy parts. The whole amp/DAC problem people were discussing is not present, as I know the difference between an AMP, DAC and AMP/DAC combo. I got a Fulla, which is a combo. That said, I have plenty of Amps lying around, 4 within arms reach from where I sit at my desk. One of them has a frequency response of DC-300kHz, yes DC, designed with transient peaks in mind. Full class A transistor amp, with a THD of either 0.000 something or 0.0000 something. Very low. To be honest, I haven't used it yet as the Fulla can drive them no problem, except for a few rare circumstances.
Thanks for the feedback though, It's nice to see people taking an interest in other people they have never met, to the extent of providing friendly, factual advice.
