Resetting the headphones also helps, I just did that and one of the suggestions here in a combo and now both ears are working well. Word of advise, there is different reset options depending on which series of Beats you are trying to fix. Mine are Solo 3's so I had to hold the power button and down volume button for 8 seconds to reset mine. Google your reset options if yours is not a Solo 3, I think others you hold the volume down button on the set and the multifunction button on the cord for 8 seconds until a blue and red light flashes.
