EP-T27 unpairs when inserting in ear


I am using EP-T27 earbuds with iPhone 6. Almost every time when I remove right earbud from the case it shows connecting to my iPhone. But when I try to insert the bud, it unconnects. I have the same with the left bud.

It have tried:

  • rebooted the iphone
  • repaired the right bud. ( can’t see the left bud connection)
  • changed different size cones.
  • started the music app before or after trying the buds.

These are almost impossible to use. My wife has apple buds and an iphone and never has these problems.
Do I have defective earbuds or what can I do?
