You often find beyerdynamic models on the Internet named "Premium". Unfortunately, this is a mistake, as there have never been such models and they also don’t exist today. We have been using the word "Premium" for a long time as a term to indicate a certain quality rating of the product. However, this is not part of the product name.
If you encounter the term "Premium", it generally, however, means the DT 770/880/990 Edition model.
