I have a BlackBerry Curve 8330 from boost mobile. When I use it to play music mp3s with a good high bit rate the sound quality is excellent using the official headphones that came with the phone 3.5mm plug and when I play music using the phones speakerphone. I have tried several 3.5 mm -male connector wires but get the following problems when playing music on both the external computer speakers. What should I do? Where can I go to fix such problem?
