billoderso5 years ago+110I use this product with a OnePlus6T and I wonder if it is normal that my headphones are just not nearly as loud as they were before.Show in original language (German)KaRaKaToS5 years ago • purchased this product000purchased this productI have a Oneplus 7 pro. & I have the same problem. My headphones with this adapter are recognised as a USB device instead of headphones. So I need the one that comes with it from OP & I have another one from 4smarts that works fine.Show in original language (German)Comment1 comment
