The serial number should be on the actual box, may say ser or sn or s/n, are any of those present? If not you may want to reach out to customer support for your area about getting them registered.
HDJ-C70 Serial Number Location
I bought the Pioneer HDJ-C70 Headphones and I'm trying to register this product at www.pionnerdj.com However, everytime I try to put all the different codes within the bar codes in the box, none of them is correct, I've tried to put one of the codes, putting some codes together, etc.
It would be helpful if someone working at pioneer shows a picture of a box of HDJ-C70 showing what code is the serial number of the product. There is no clear serial code of all the numbers in the barcode of the box. No 'serial' is shown clearly, just numbers and numbers.
I've read that the HDJ-2000 has no serial whatsoever. Does the HDJ-C70 have a serial in the box? If not, why pioneer is asking for a serial code for that product?
I have the same problem. A pair a C70 but is not possible to find the sn
Same problem any one find it I got HDJ-700-K
