I would argue he wasn’t lucky, but that you were unlucky. The majority of Moondrop products do not fail, or they would be out of business. I’m not trying to discredit your experience, and I do like Moondrop, but I haven’t kept their products long enough to potentially have one go bad on me.

With all of that said, it sucks your Arias went bad, but I think you got unlucky, as many other people have.
