Needs better sound quality

Littmann has done a great deed in developing this app. It provides "lessons" on diaphragm/bell positioning and heart sounds, but it fails in sound quality. On both iPad and iPhone with the volume high, you can barely make out the heart sounds it produces. This is even with placing the speaker directly next to your external canal.
I would love to use this more as a mobile teaching model, so that students may hear what I am trying to explain when a patients with similar conditions are not available. Littmanns only suggestion is to wear headphones, which is not always practical.
