Croma Earphones (EA7290 EM881J) Teardown/Repair Help.
I have these Croma Earphones with Mic (EA7290 EM881J, Black) ear phones they have stopped working and I think its a simple case of disconnected wires that need to be sodered back .However I cannot find a way to open these earphones they apper to be factory sealed however there may be a techinique i am unaware of that could aid me in opening these earphones here are a few images of the earphones.
The earbuds stopped working one after the other so i am sure that the jack is not to blame
Things i have tried
I firstly took the rubber pieces out so they don't melt or deform then i placed the earbuds on a workbench where I hanged a hairdryer directly on top of it the distance between the hairdryer and earbuds has about 5 to 10 cm I turned hairdryer to max heat output then waited for 3 minutes then I used gloves and tried really hard to pull the 2 ends of the earbuds apart but it didn't work. the thing didnt came apart and it didnt even move and i feard if i heated it up any more the internal componets might get damaged themselfves
