Wireless communication can be achieved with the Thinklabs One Stethoscope by connecting the stethoscope to an external Bluetooth transmitter. The Bluetooth transmitter can then be paired with Bluetooth devices like wireless headphones, speakers, or another Bluetooth Transmitter which is in receive mode. (Please note that the transmitter cannot be paired with smartphones or tablets, only with listening devices such as headphones and loudspeakers.)
We have tested and we recommend a Bluetooth Transmitter.
