Hey Guys/Girls!

I was wondering if you can help me!

I want to puchase the MDR-DS6500 headphones. Can I used more than one headphones with the main dock/headphones or do I need another headphones/dock or is this only 'one per household'?

Also if I can get additional headphones, where can I get them from as I cannot see them anywhere on the Internet? (Not sure if I have answered my initial question there!)

Also does anyone recommend the MDR-DS7100 headphones? I have seen them and was considering them.

I am undecided between the two!

Thanks

Jas
