This!
I may get a pair of the ER4SR. I wonder if they did anything to quiet down the cord. It's too bad they didn't make them more comfortable. I hate that the ER4 stick so far out of the ears.
Ok, here is what EtyDave says about the new cable:
"The cable material is different than the older model. It's a bit softer and more supple (*cough* marketing term) than the old cable so it feels nicer in the hand than the old cable. Preliminary feedback has been people feel it's slightly less microphonic.
But realistically, the earphone still seals deep in the bony portion of the ear canal, which doesn't help microphonics. As before, using the shirt clip will help, as will wrapping them over the ear (which is slightly easier than before because we modified the angle of the strain relief)."
