These earbuds were bought last year and were never used until my neighbor gave them to me last april or may. They started out working great and I would listen to music everyday on the way to school in the bus. But then all of the sudden about I guess 1 or 2 weeks later I go to use them and its very quiet and i turn the volume up and its all the way up and I remember it being a lot louder before. And I also noticed that ambient sound has stoped working also. (Before this happened I cleaned them and I didnt know that you werent supposed to use an alcohol wipe until I saw it say so online afterwords. Would that might of damaged somthing that had to do with it maybe?
