Home setup in sig.
I have a set of Klipsch S4s lying around that I have been using at the gym.
Two things get on my nerves about them:
When I'm running or even jogging for that matter, they:
1) Fall out, or lose seal, no matter which tips I use
2) I can hear my strides as *thud* *thud* *thud* every time my feet hit the ground
SQ wise, these are fine for the purpose of working out.
I've HONESTLY (and never thought I would say this) considered Bose's new IEMs (the green ones) that are geared towards exercise.
