A manufacturers warranty is for products in their original state. Any modifications done without the prior authorization of a manufacturer cannot be controlled. There are various modifications being done to Ultrasone headphones that are not authorized by Ultrasone, therefore they are not under our control. The technicians conducting these modifications, though they may be well qualified to do so, have not been authorized or trained by Ultrasone to conduct any type work on Ultrasone products. Thus, any modifications that are not authorized by Ultrasone, are void of the manufacturers' warranty.
Before anyone goes ballistic here, I will try to find a solution to this. This will take some time, so please do not expect answers over night.
I'll keep everyone posted here as to the status.
