Yeah, I heard the stock cable isn't the best, I just wasn't sure if this loose plug is the cable's fault or the connector itself on the headphone - as the latter would be more complicated to replace I imagine. So you say it's probably the cable itself right? Maybe I should test it by switching the left and right plugs and see which one is loose that way?
I plan to buy a balanced cable for it.
FWIW, I like the stock cable quite a bit: It's light, so it doesn't pull on the cup, it's quite sturdy - can't even count how any times I ran over it with a chair, or stepped on the wire and the connector - and it sounds very good compared to the factory HD650 cable and a 5' Mogami an as aftermarket termination. If anyone needs a HD650 cable, I have two that are never used. Why two? Because, I wanted to hear an older HD650 cable and the latest version. They sounded the same.
