Overall these are very good with not as good as a mic as the AirPods pro but a good option for android users ( I switch between the iPad Pro + OP7 Pro on these very easily; it’s just a matter of disconnecting the Bluetooth on the devices and it syncs pretty fast).
Sure you can pair it up to 8 devices. Great! It will only EVER send audio to the first device. There is no way to switch audio between paired devices. No we are not trying to stream from multiple devices at the same time. We're switching from phone to computer. That doesn't work. It will only stream music from the original paired device.
