Subpar quality

Sound quality is lacking, at times there is a lot of static or a high pitch ringing in the background over whatever I am trying to listen to. Also the volume intensity is strange, the lowest notch still results in fairly loud music out of the earphones. This was not a problem without the adapter. Additionally, the volume controls on the earphones themselves (standard apple earphones) is not compatible and can not be used with the adapter to control volume.
