eSense Skin Response
Adapter for Android and Apple devices
Some newer Android and iOS (Apple) devices without the classic 3.5mm headphone jack and with the newer Lightning / USB-C connector also work perfectly with the eSense.
You either need an original Apple USB-C (https://amzn.to/2OQYssu) or original Apple Lightning (https://amzn.to/2SJVg37) to 3.5 mm connection adapter (not included in the scope of delivery of the eSense).
Android & Apple
Alternatively, you also can use any other adapter with a DAC chip. We recommend this adapter on Amazon: https://amzn.to/2SnAUA1
An adapter is also only needed, if at all, for the eSense Skin Response, eSense Temperature and eSense Respiration (as these eSenses have a 3.5mm headphone jack). An adapter is never needed for the eSense Pulse and eSense Muscle (as these connect to the device wirelessly via Bluetooth®).
