Hello,

I thinking about buying a new pair of headphones.
I would like them to be cordless so I don't keep getting caught
up in the lead. The two that I like the look off a

Sony MDR-RF850RK Wireless Closed Headphones
Sony MDR-RF820RK Comfort Design Wireless Headphones

Has anyone got these models? What are their strengths and weakness's?
Has anybody got any other makes that they would like to recommend?

Many Thanks.
