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.

Please follow this order when using the adapter:

1. Plug the adapter into your smartphone/tablet.
2. Connect the eSense to the adapter.
3. Start the eSense App.

If the adapter with the eSense is only plugged in after the app is already running and in Free Training mode (even if no training has been started yet), connection problems may frequently occur.

If the eSense is not recognized and the signal fluctuates irregularly or erratically, close the eSense App completely and restart it. The connection should then work properly.

Apple

You will need one of the following original Apple adapters (not included with the eSense):

• Apple USB-C to 3.5mm Adapter – For all Apple devices with a USB-C port (iPhone 15 and newer, and newer iPads). Compact, reliable, and with an integrated DAC chip for lossless audio transmission. https://amzn.to/41zD2Gd
• Apple Lightning to 3.5mm Adapter – For Apple devices with a Lightning port (iPhone 7 through 14 and older iPads). Apple-certified and fully compatible with the eSense. https://www.mediamarkt.de/de/product/_apple-mmx62zm-a-2179668.html

Apple & Android

Alternatively, you can also use any other adapter with a DAC chip (Digital-to-Analog Converter). A DAC chip is required because USB-C does not transmit an analog audio signal – the chip converts the digital signal into an analog one that the eSense needs.

We recommend the JSAUX USB-C to 3.5mm Headphone Jack Adapter (4.5★, over 7,600 reviews on Amazon). This simple and affordable adapter works reliably with the eSense and is compatible with most Android devices as well as newer iPhones with USB-C: https://amzn.to/2SnAUA1

USB-C Adapter with Simultaneous Charging (2-in-1)

Many newer smartphones and tablets only have a single USB-C port. When using the eSense with a standard USB-C to 3.5mm adapter, you cannot charge your device simultaneously during training. The following 2-in-1 adapters solve this problem: They provide both a 3.5mm headphone jack for the eSense and a USB-C charging port with up to 60W fast charging (PD).

Important: If you do not need the simultaneous charging feature, we recommend the simple JSAUX USB-C adapter mentioned above – it is more affordable, more compact, and perfectly sufficient for eSense use alone.

We have explicitly tested the following 2-in-1 adapters with the eSense Skin Response, eSense Temperature, and eSense Respiration – on various Android devices (Samsung Galaxy, Xiaomi, Huawei). All adapters worked flawlessly with the eSense in our tests:

YUETUOL USB-C to 3.5mm Headphone Jack Adapter with PD 60W Charging

This compact 2-in-1 adapter features an integrated DAC chip with Hi-Res Audio (32bit/384kHz) and supports PD 60W fast charging. It is compatible with most USB-C devices, including Samsung Galaxy, Huawei, Xiaomi, and newer iPhones with USB-C.

BENFEI USB-C to 3.5mm Headphone Jack Adapter with 60W Fast Charging

The BENFEI adapter also features a DAC Smart Chip for Hi-Fi audio quality and 60W fast charging. A particularly practical feature is the hidden cable design that prevents cable clutter. The manufacturer offers an 18-month warranty.

An adapter is only needed, if at all, for the eSense Skin Response, eSense Temperature, and eSense Respiration (as these eSense sensors 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®).

We tested 11 alternative Lightning adapters from third-party vendors – only two of them worked. Therefore, we recommend either the original Apple Lightning adapter (https://www.mediamarkt.de/de/product/_apple-mmx62zm-a-2179668.html) or this compatible Lightning-to-3.5mm adapter, which we have successfully used with the eSense and also offer in our shop: Compatible Apple Lightning to 3.5mm adapter https://mindfield-shop.com/en/product/compatible-apple-lightning-to-3-5mm-adapter.
