Not sure about the new x version. Didnt realise they were discontinued. I would still try to get a pair of the old version at a local music store. $179.99 I think I paid 2 years ago at Axe music back in Calgary. I think the x version improves on the creature comforts like a detatchable cable and optional colors. Same sound afaik. Maybe Ken would know? Hes a fan too.
