If you are within Germany, you should firstly take your faulty product to your beyerdynamic dealer. The dealer will then arrange to have it safely sent to our customer service. Once the repair has been carried out, you can collect the product again from the dealer. It is also possible to send the faulty product to us directly. Please complete the repair form. The processing time for repairs is generally 5-10 working days. For repairs that are within warranty/the guarantee period, please don’t forget to enclose a copy of your proof of purchase. If this document is not included, we will be unable to process the repair under the warranty/guarantee and you will be charged.
