Not trying to point my finger at the OP, but I have been wondering this for ages..
Why do people wear expensive IEM's for the Gym/exercise? Shurely (geddit) the chances of snagging a cable, ruining the driver with sweat, or some other mishap are pretty high.
I would say get a couple of pairs of cheap as chips IEMs, Treat them as disposable.
If you casn listen t music and notice the sound from the headphones, are you trying hard enough??
