I use headphones and an auto reverse walkman for the audio tape. Pop it in the pocket or clip it on the back the wires from the headphones down the back where it stays nicely out of the way.
The reason I mentioned looking at the shoes you're wearing when you do qi gong. Usually I've been wearing flat shoes but yesterday I went to my brothers place and was wearing joggers. After popping his kids into bed, reading them 3 books (and after the tweedle beetle paddle puddle bottle battle muddle... I said no more 
). 30 minutes later after all the delaying tactics were finished they were sound asleep and I did my hour of qi gong I lasted maybe 10 minutes into the exercise and my feet were hurting and was surprised that they were hearing because I haven't had this problem since the retreat. Then I realised the difference was the shoes. Kicked them of and I was in the emepiness.
