Good for network wiring diagnostic. It would be great if it can pipe the noise to Bluetooth audio. I can pair a headphone to it, plug this into the network in another room and still can hear it while checking the line connections on the switch/router.

That audio port is blasting out a total bandwidth of 100 Mbps (4 bits at 25 MHz) versus 768 Kbps for BT audio, assuming a high quality codec (16 bits at 48 KHz), so not without loss.

Can be downsampled for the purpose. It's just noise after all.
