Just three weeks after I bought these Sony MDR-ZX300 headphones, I accidentally dropped it at a height of three feet. Right after, there was an irritating buzzing sound coming from the left cup—nothing could be more irritating than that. It would often manifest in most of my favorite tracks. The sound was comparable to the hiss that comes from a person who’s just gotten braces/retainers. I ended up banging it against the table in hopes that the impact will make it work normally again (I have a skewed way of thinking), but to no avail. That is, until it slipped from my desk a few weeks after! The sound went back to normal. Perhaps the headphones thought of inching closer to the edge for the self-inflicted fall (I think too much).
How about you? Have you encountered gadget quirks?
