I have had the EF 61's for about 3 weeks, and today i had my first problem. The left speaker is making a weird low pitched grinding noise in the background of playing music. On some songs you can't notice it, but on other songs, the weird noise it makes gets very loud and noticeable. Other than that noise, the speaker itself sounds fine. Whats going on!!!
