Please dont use this thread to complain about the quality control of Grado. What I wanted to focus on is things you can do in the situation of your Grado HF-1s having a problem. What steps to take, what you have already done, what happened, and overall outcome.
Grado is not a major giant company that is able to do the things you've come to expect from rich mega corporations. It's a small place in Brooklyn that manufactures and produces headphones. Notice that these phones are hand made so theres bound to be errors here and there. I'm lucky that I live so close to Grado Labs. I'm also grateful that Grado is what it is, a small company that's willing to communicate with people first hand about their problems and is humble enough to not treat you like "just another customer." If you imported your headphones you should of done your research and assess your risks of importing before purchasing a product. It's not right to blame a company for your own irresponsibility and ignorance of not looking into the subject. It is understandable that when you purchase a product, you'd assume for the best that nothing bad will happen, but hey "crap happens." Quality control is another issue that I do not want to talk about on this thread. In other words, just stick to the subject.
