Recently I've been having trouble listening to music. I wonder what the hell is happening... I always heard that these pair of cheap sony headphones I'm using is rather good for the price. The strange thing is that, though sound quality is not bad, my ear feels a sharp pain whenever I listen to it for more than 15 minutes. , anyway, today I watched 3 episodes of an anime on it, I am having an ear-ache for hours (about 8 by now)... no one else used this headphone seems to have that problem. I'm sure it's not my ears, because when I used any other brand (even other model of sony) headphone, my ear stays fine. Any suggestions to why? Any cure? Any ear-ologists on this forum?
