The Y split the HD650 is too short so I usually end up garrotting myself when I take them off absentmindedly.  To remedy this I put them on from back to front with cable running down my back.

Then when I take them off my ponytail gets caught in the in the Y split...

Did you knot the ponytail? Or is this a case of the ponytail having a will of its own and not liking the knot?

Some people have hair that cannot be tamed once it is long...

I just use one elastic hair band.  The problem is that my ponytail is longer than the Y split so it works it way out and over it.  I measured the cable, an it's only 9.5 inches from the ripstop to earcup.  My Lambdas have 15.5 inches to the ripstop.  I never have either problem with them.  Unlike the 650s they also have a physics based excuse for not being single entry.

That makes me wonder what HD650 drivers would sound like in a 558/598 frame...

I f***ing hate the rubber bands of my portable DAC/amp! I almost want to cry!
