The Standard Electrodes tend to be more comfortable for most users. These electrodes have soft gel that adheres to the skin and is optimized to provide consistent, comfortable nerve stimulation in most conditions.
The Sport Electrode has a unique sport gel designed to better hold up in situations with high levels of humidity and perspiration. The Sport Electrode absorbs less moisture, but is otherwise comparable to the Standard Electrode. Sport electrodes are also appropriate for seasonal or occasional use, as needed.
