Make a Headphone Cable with Dual Unbalanced Mic cable?

guys, is it a good choice to diy a single-ended headphone cable with any unbalanced cable (eg: mogami w2528 dual )?



I recently found a mogami w2528 cable lying around & thought of diy a headphone cable, I just want to know is it good thing to use shield as the ground for the each headphone cup left/right end and connect both shields to the ground/sleeve of 1/4" trs connector at the other end? could this sort of a configuration (or cable) introduce audible hum/ noise to the sound?
or should I use a balanced cable like mogami W2534 ? is there any benefit of doing that with a balanced cable?

 

This should work fine, the w2534 cable needs some heatshrink or sleeving to cover the ends after the split to each cup. With the w2528 you don't have to do this so it is the easier and neater solution. Performance should be similar or identical.
