Bluetooth connection to unknown device

Lost previous post describing the following: iPhone 13, iOS 17.7.1 and streaming Apple Music to AirPods Pro I 1st Gen., while listening to music, my device suddenly switched and connected to an unknown device. The unknown device was playing music not in my Apple Music. Over the past year iPhone 13 abruptly stop playing Apple Music, as if paused, a couple times a week. Yesterday, some other music, not in my Apple Music, could be heard, if only perhaps 15 seconds. The only Bluetooth device in search is SCOSCHE BTFM4. It did not show being connected. Is this a common issue? Is there something wrong? Something I could fix in settings?? I truly hope others cannot somehow pick up what is on my device.

Thanking in advance.
