As this question has been asked twice for both models, after researching both, I have the following answer for both headsets:
I was able to do a search and it looks like the manufacturer here does not use different EAN codes or manufacturer numbers for the different batches. In this case, it is unfortunately not possible for us to predict which headset belongs to which production run. In any case, you have a manufacturer's warranty if something should go wrong with the headset. The link to the other question: https://www.digitec.ch/de...
