I recently started working at a construction office in another country. I usually listen to music when working, and I saw a headphone jack in the wall, so I thought it is radio or something, I plugged in my headphones and there was this buzzing noise and something started to smell, now they do not work anymore. I took a picture of the jack, are my headphones incompatible with this country standard? Are they damaged?
