I only listen to music during the cardio part of my workout, so that makes it 30 minutes, 3 times a week = 90 minutes. Considering how little this is, I just had to have some good sound. I'm not a big fan of IEMs, but it is what it is. I also have a JH3A/JH16 rig which I don't really like and will most likely end up selling.
As far as taking the LG to work, it's not a practical option for me, given that I'm seemingly always in meetings or conferences. I'm just not listening to music at work - ironic, come to think of, since our company is in the business of audio streaming (got over a couple thousand radio stations on our network).
