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!

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