http://www.sennheiser.ca/main.php?node=ct_01&pro=648 I can get these for about $80. At Futureshop, they sell for $210cdn and I was wondering if they're worth it. I don't require that they be wireless, but it seems like it'd be a nice feature to have. I'm assuming they work on the iPhone(3G), so there shouldn't be a problem with compatibility. I currently use the JBL 410's and wanted to know what difference I'd get with these or if I should consider a different pair.
