No recommendations or anything. No arguments should occur. YMMV applies as always. Nothing but my experience. Just food for thought. If you find the phones off or not quite to your liking maybe you can try out some things if you so choose. Like dosley01 said, he might have wanted to try that cause you don't know till you try. No results are guaranteed or even that one might like or even dislike anything they might try. The individual and his/her gear, preferences, hearing, etc makes it far from a science.
Music_4321 hasn't heard a difference in cables. Average_Joe has a thread comparing the differences between 13 cables. Dale said there will be upgrade cables. I can't say anything about who hears what or doesn't. Just some info that everyone is free to ignore or to try if they choose and see what results they get.
