Sennheiser replacement cables

Not correct, they are interchangeable and they all have a 1/4" plug.

The 650 cable is by far the best of the two, and cheaper to boot.. A no-brainer. :)

All after-market cables are better than the Sennheiser one though, so you might want to check these out before doing anything.

Really Sfar? They're all 1/4" where I live. :) Perhaps they can be ordered with either, that would explain things!

In any case, the three phones can all use the same cables since they have the same connectors. The 600s sound slightly better with the 650 stock cable, so that could be a worthwhile upgrade. However I still recommend getting something better, there's plenty of good ones out there. :)

Right, thanks for clearing it up. Weird, my 600s came with a 1/4" stock cable, no adapter included either!

But you're right of course, it doesn't really matter since it's so easy to go from one to the other. :) I guess they've made it so due to all iPods and such, that only has the 1/8" connector.

In any case, the 650 cable works fine in all three phones, and is considered the better cable.

Ah, thanks for clearing my confusion up, Fatparrot. Yes, mine is a few years old.

84audio - glad you tried it! Next time, try to hear the Zu Mobius (preferably on a headphone amp too) it's in my opinion a lot better than the Cardas, which in itself is much better than the stock chord.
