They come from inside of a person, your pet or a plant and emanate outwards for us to discover and to appreciate. Stemoscope detects sounds and transmits them wirelessly to your smart devices, phones or tablets, eliminating the cumbersome tube of the traditional stethoscope. A user can choose either a wired or wireless earphone to listen to these engaging sounds. Stemoscope is the world's first wearable stethoscope. With the specially designed strap (might need to be ordered separately), you can easily wear it or carry it easily with you. It is so small that you can store it with your earphone in the same bag. The stemoscope comes with an engaging App with many rich and useful features that are easy to use by anyone. You can save the sounds and the locations where the sound comes from.
