Bought the eph-100. Got a pretty decent deal from audio affair, 84 GBP (~125$) including international shipping.
Thanks everybody for the help!
To run of 42 kilometers with them and lose 3 liters of water, it is extremely brash with them?
I'd think it's a bad idea to use the eph-100 for this, because of the moisture issue, and if you apply pressure on the cable while running, it would wear out faster.
I personally use either the koss ksc75 or the pmx680 for jogging.
I don't know if the eph-50 is worth particular attention, at its price range.
It looks much more bulky than eph-100.
