I have a new mobile the galaxy a16. I cannot use my headphones with it because you need headphones with a USB plugʻ and mine is a round one that I can use on my laptop. I bought an adapter for £10 and basically I plug the adapter into the phone and my headphones into the adaoter. I put a youtube video on and turned up the volume and there was no sound from the video. Either I have a faulty adapter or I need to adjust my phone. My headphones are good quality and expensive and work on other devices so it's got to be the adapter or the settings.has anyone else had this issue? I can phone EE or go to a phone repair shop in my area to see if they think I've got a faulty adaoter or what. £10 is a lot to pay for an adapter that does not work. If it is the adapter i can take it back and get a refund d
