As I understood, the buds can be used like every other Bluetooth headphone by just pairing BT. So what's the purpose of the corresponding app? Will the headphones work without the app?
Are they able to pass something (audio, data, statistics) to Google by just connecting them to the Pixel without the app? I think about direct internet access by Bluetooth tethering.
I got the earbuds bundled with my P7 recently but would only consider to use them without proprietary app. Otherwise I would keep the box closed and sell them.
