I don't know whether they were mentioned:
Audio Technica ATH-AD900X (open air) vs. ATH-A900X (closed back)
What about the Sony MDR-MA900 under $199?
How about the battle of the open-air 900's: ATH-AD900x vs. MDR-MA900?
I've ordered the A900X but they got mis-delivered by the FedEx to some other address!
