There should be no problem playing eRemedies on any kind of device. Computer is as good as cellphone as far as we know. And we expect that there should be no difference between cellphones, as they all play songs fine.
It is true that this is a new invention. There are differences in quality of speakers. So far we have not observed this in veterinary or medical practice. Once eRemedies are used globally on all kinds of devices, we will be tracking this question carefully. If we do detect a problem, we will make an announcement immediately.
