The good news is I have at least two left. I am sure that once I wear them, they will last two full days like their brother. I used them as they should be used. I didn't even take it with me from my apartment, I only use it at home to watch TV at night so as not to disturb anyone. They worked fine for a couple of days with a light load, I live alone, put them to bed, woke up and the right channel stopped working. It's really very sad, they sounded great when served and the fit was comfortable. It's a pity that the Chinese are so inattentive to details.
