Thank you for the post Maxvla. I have just read so many things about people replacing their cables on their cans that I wasn't sure if it would be a good idea or worth the money. Anyone else have any thoughts on this?

Cables are one of those things most of us decide we need to explore at some point in our audio journey.  The engineer in us may not want to believe, but in a largely subjective hobby sometimes the only way to convince yourself one way or the other is to try it yourself. Only you are going to be able to say if it's worth the money.

Look around for a used cable first... hopefully you can experiment on the cheap before you make a big investment.  Are you game for any DIY?  You can build a few cables to compare as well.

If you're searching around and finding threads like http://www.head-fi.org/t/641565/best-aftermarket-cable-for-the-sennheiser-hd-650 you'll find some examples of cables that are out there.  Cable "supporters" will typically tell you the differences are subtle and typically done as one of the last tweaks, after you get the rest of your rig right.

Good luck, and have fun!

thank you olor1n and shipsupt for your posts, I will take what you are saying into consideration. I was offered a used set of cables for the HD650's, we'll see if anything can come of it.

Thank you both again for your posts!

If you're thinking about DIY:ing cables, I might recommend my quick article on it:

Cables are in my opinion the last thing you should invest in (and there's almost always something else to invest in).
Unless one or more of the following are a problem:
1) Aesthetics
2) Length
3) Termination

I wish you all the best and remain critical if possible, you might try/borrow a friends identical headphone and try them out of the same amp, however... there is a possibility that differences in useage of pads / drivers will actually contribute more than the actual cables differences. But that's me. I'm a cable-agnostic. Haven't heard anything yet that has convinced me.

If you can get a better amp, do that first, and if you can get a better source, do that first. In my experience cables can make a difference, though perhaps less so with headphones than other areas. The difference also will be less if the cable is going to a socket followed by a stock wire than directly wired to the driver. Headphone cables tend to be fairly straight forward braided and twisted pair designs, there's usually no advanced geometry going on like you'd have with a high-end speaker cable. The small gauges required are also very affordable to get as bulk wire, even for TOTL OCC stuff, so you could easily make your own if you have some basic soldering experience. Just keep in mind that litz wire is generally a big PITA to deal with, you're better off regular stranded wire.
