Just bought my first set of bluetooth headphones and am having trouble figuring them out. I can get them to connect and play music no problem but when I try to use any other app on my phone my Bluetooth disconnects. I have a iPhone 6+ running current ios update. Is what I’m asking the phone to do possible and how do I fix it if so. Using pandora and iPhone music app. It’s a really cheap pair of headphones brand name of canz.
