Theres a big newsitem here in Holland about headsets/headphones and the amount of BPA/BPS that is used in them and the Razer Kraken V3 is one of the worst headsets in the list. Everything is listed red.
What it comes down to is that usage of this headset can weaken the immunesystem and can also lead to allergic reactions or infertility.
Now ive been using the v3 Hypersense for a few years now and my son also has one.
Im not afraid or something, but a response from Razer on this thing would be nice, since they're listen in that list as one of the worst models available.
The list of tested headsets/phones is available here as a pdf:
