Oh my... just received this headphone 5 mins ago to watch movie/youtube, I know I had to post my first impression.
This headphone has awesome bass, well not as nice as LCD2 or TH900 but it's there, seriously good sound quality.
I paid this for $169 USD so considering the price factor it's an awesome deal compare to TH900 $2000+tax or D7000.
I say it's about 80% of LCD2 in terms of SQ. more to come guys.. enjoy your ATH-A900X.
You know you can find these, for $100 refurbished on ebay right!
