I bought KOSS Pro DJ200 phones. They retailed for $150 and London Drugs had them marked down to $75. I got them in brand new box and eagerly waited to try them on my iphone4. I selected CBC radio and played and acoustic session from someone i never heard of.. I was in the kitchen cooking with the phone in my housecoat pocket and it was so clear.
2) I decided to try them in my Brystons. KOSS sounded ok but nothing like the 'air around' the STAX SRD-6's to play the BCD-1 . I engaged my BDA-1 and played around with it. up sampling and mono.. it was fun
I would be keen on burning a disc and trying the BDA on a stick... who knows when but it was fun up-sampling and stuff. But I realize I don't need overkill on the SKYTRAIN TO WORK but for pure listening it was NEAT to compare them
