Next, remove the soft lining behind the cushion. This is held on with adhesive and is easily removed by hand.

Once the soft lining is removed from behind the ear cushion, two screws will be exposed.

Carefully remove the two 5 mm screws with a precision screwdriver (PH00) and put aside.

-
Flip the earphones back over and carefully pry around the outside cover of the earpiece.
-
Try a plastic opening tool before moving on to harder metal tools.
-
This cover will come loose with moderate pressure.

There are 3 screws holding the motherboard to the earpiece.
-
Remove these screws to make the next step easier.

bei meinem QC25 hat sich auf der Seite mit dem Kabelanschluss die Lautsprecherkapsel gelockert und klappert jetzt. Wenn ich auf der Seite die Alu-Abdeckung entferne, komme ich an die Kapsel noch nicht dran, weil da eine weitere Schicht Plastik vor ist.
War da schon mal jemand und kann weiterhelfen?
