The Thinklink Mobile Kit, shown in the image to the left, enables you to connect the Thinklabs One stethoscope to most mobile devices (phones and tablets). This accessory comes with the purchase of the Thinklabs One, but you can also purchase it from the Thinklabs store.
Combined with the free Thinklabs Wave app, available in the Apple App Store and in the Google Play Store, you can record the sounds captured by the Thinklabs One (while simultaneously listening with the Thinklabs ear buds) and then play those sounds back on your mobile device.
