I just bought them today. Took the mesh off to check if everything was in order but then noticed a a small dent on the driver a picture is attached below.
Just next to the big blue arrow. It does not seem to be a hole but still i dont think it should be there. Any one from Sennheiser wants to comment. Thanks. Would this affect the sound quality of the driver. Just an explanation as to what this could be. Should I return it and ask for a replacement? For £600 product a little worrying.
