Newmanoc is correct...assuming your cans are of decent to good quality you may want something better. Cary is known for having good phone out jacks, but most are no more than a "cheap" throw in (even on major brands). Be aware that it will likely take you $200 and up to make it worth while, and depending on what cans you own I'd even say more like $400 until you start to get the most out them.
