In my first test, I had Bluetooth and Wi-Fi enabled outlined here: Testing a Cornet ED78S with iPhone 5s when receiving a phone call. A recent viewer commented on performing the test again, this time with Bluetooth and with Wi-Fi disabled. The results were much different. I tried to keep the testing conditions as close as possible to the original video, including performing the test at the same time of day. The video below shows the updated results.
