I love using this with the Bluetooth feature so that I can keep it in my pocket without all the bulkiness of the tubes and earpiece. The only downside is, I was hoping that with this being an amplified stethoscope, it would be louder. Whether I use the Bluetooth AirPods or the standard “ears”, it is quite difficult to hear. I do wish the company sold some sort of case for the chest piece alone. I was able to buy one from a competitor that fits pretty OK, to keep it protected in my pocket.
