Hi Holly, and thank you for supporting Harman Kardon! Your Soundsticks III complies with the EuP regulations, which specify that speakers like yours, among many other products, must enter standby after a certain period of inactivity. So, if you play no sound and touch no button on the speakers, they will enter standby. One detail: if you turn the volume way up on the SSIII, and then control listening volume on your source, the result will often be that the input signal is becomes so weak that the speaker sees it as silence, and shuts off. The way to avoid this is of course to increase source volume to maximum, or close to max, then control listening volume on the SSIII touch pads. If you want want a speaker without this mandatory function, you can find a second-hand set of the earliest version of SSIII, which did not have this system, since it was built before the EuP regulations existed. You can also use the SSII, which of course never had this system, since it is older. It plays just like SSIII. I hope this helps.
