Sorry for the lazy request - gotta get some phones for my wife to use with a Sangean portable fm radio while she walks for exercise. Cheap, durable, easily stored are all priorities. (No, she won't go for Etymotics!)
Thanks to all,
I have both of these and like both of them. The main difference is the Porta Pros are more conventional over the head model while the 50's are over the ear. The KSC-35s are getting harder to find as they are I believe out of production.
