Bluetooth headphones, Apple Watch and iPhone
I have a pair of Plantronics Backbeat Fit bluetooth headphones. I just got an iPhone Xs Max and an Apple Watch s4. Today at the gym I left my phone in a secure locker after having paired the headphones and started running audio whilst doing my workout. The Watch can control the audio, stop/start/pause etc. I got to a part of the gym where something obstructed the bluetooth signal from the iPhone to the headphones and the audio stopped. The Watch still had connectivity and I was able to pause and resume the audio. I went back to the locker and could here the audio coming from the iPhone. I was able to pair the headphones directly to the Watch, but no audio came through. Can someone explain how this all works to me please. I assume the Watch has better receptivity of bluetooth than the headphones. I know it is possible to play stored audio files on the Watch to the headphones, but it seems I cannot use the Watch as a relay to stream audio from the iPhone through the Watch to the headphones? Thanks for any suggestions.
