Old, just judging by the cable. Yeah the cable is too stiff, I will probably put the HE connectors on a HD650 cable. Can't do HE6 or anything super inefficient since these are only used at my work during lunch. I have Omega 1 and 2 for home use.
I also got them in a trade for my Lambdas, so I don't think I will be trying anything else since I'm really happy with them.
