As noted, Nordic don't have any Classic BT products - so this is really not the place to ask such questions.

Excuse me, In my Question 1, you said the device is based on classic Bluetooth. Therefore, another bond phone could connect this device when the device is connected.

This classic Bluetooth protocol? Does The classic Bluetooth not distinguish between ADV channel or connect channel?

I assume classic Bluetooth solutions are also improved over time to reduce power consumption.

For the long term we expect audio to move to Bluetooth low energy also, but this probably several years out still.

All current Bluetooth audio solutions are based on classic Bluetooth (also referred to as BR/EDR), not BLE.

We don't support this in any of our products, so the nRF52 would not be suitable for this kind of application unfortunately.
