Not sure why, but BT experiences interference when in my pocket. The signal gets choppy when sections of my torso get in the way. Which is always when my phone is in my pocket. So I got USBC headphones/dongle.
On a bike ride, I noticed the audio was starting to disconnect. This happens often on rides and runs since the USBC plug sticks out a lot from the port and slowly wiggles loose. Except this time it wasn't loose. The leverage of the long plug on the short connector damaged the port. This never would have happened with a headphone jack. It has a strong connection that can rotate freely. Now I have a phone that can't charge or play music.
My next phone will be a sony xperia some they still have the jack and still allow the bootloader to be unlocked.
