I bought a pair of Drop x Sennheiser pc37x headphones and was told that I would need to contact Drop for customer support by Sennheiser. I have waited days for a response and still have not received one. If Drop wont respond to me maybe other customers can. The headphones are having audio issues. They sound great for music and Youtube videos but are muffled on Steam bought games. I bought a DAC Amp to see if that would fix it, I have changed the power input and that did not work either. I do not know what else to do especially since Drop does not seem to have a phone number to contact.
