Will I hear buzz from the speakers if I place my phone near them?

All Audioengine speakers are video and magnetically-shielded, however "GSM buzz" cannot be blocked by magnetic shielding. What actually causes this is your phone being in 2G or "EDGE" instead of 3G or 4G. For best results when using your phone as a music source, ensure that it's operating on 3G (or 4G).
