Right earphone do not work

Hi

Try cleaning the lightning connector with cotton buds and isopropyl alcohol to clean off any debris that our human eyes can see

Also try cleaning your lighting port with a sewing needle as it’s surprising how much dirt can hide in there

Also make sure your audio is on stereo but doing this

Settings>accessibility>audio/visual>Scroll down to balance and make sure it’s in the middle

If these methods don’t work inspect the cable for discolouration,cracks and bends And let me know about them so we can adress them accordingly

Hopefully this helps

Thanks:-)
