Begin repair by removing the ear cushions.

The cushion is held on by a few small plastic clips. Pry carefully with plastic opening tool or fingernails.

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 (4.80mm) will be exposed.

Carefully remove these 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.

Once the inside of the headphone is exposed, use screw driver (PH00) to remove the two 4mm screws on the black speaker cover.

-
Remove all soldered connections that are connecting the existing speaker to the headphone. For help with this step see this guide on How To Solder and Desolder Connections

Hi, where did you get your replacement speaker from, (there are so many on eBay, I have no idea which ones are good quality)?
Also, do you recommend replacing both speakers at the same time, or is it ok to replace just the broken one?
Thanks
I repaired a headset of this type after this instruction. That went without problems. It would be a speaker defect. However, one pair cost specifically for this headset in the "Bay" only € 1.29, or a speaker just over 60 cents. I did not notice a difference in the sound quality !!! You can buy the speaker also "original" from Bose for about 22 €, but think that comes from the bay! So much for Bose!

Ich habe nach der Anweisung einen Kopfhörer dieser Bauart repariert. Das ging ohne Probleme. Es wr ein Lautsprecher defekt. Allerdings kostete 1 Paar speziell für diesen Kopfhörer in der “Bucht” nur 1,29€, bzw. ein Lautsprecher nur etwas über 60 Cent. Ich habe keinen Unterschied in der Klangqualität wahrgenommen!!! Man kann den Lautsprecher auch “original “von Bose für ca. 22€ kaufen, denke aber, dass der auch aus der Bucht kommt! Soviel zu Bose!
Does anyone know where one could get a replacement for the internal speaker cover, mines kind of melted. is there a way that anyone has a 3D model so I can get it printed ?
thanks

Do you need to apply fresh glue to reseal the speaker cover, and if so, what is the best glue to use?
