The sound (for me anyway) is unfortunately very noisy, distorted highs quite as deep. In addition, with me in the apartment at all 3 selectable radio channels repeatedly strong interference added (I live in a big city, but not on a radio technology particularly polluted place) and when no sound is transmitted, even repeatedly any radio station, very noisy and extremely noisy.
Therefore, I love these headphones have no joy when Sony ours but should bring time with digital transmission on the market, I would strike immediately.
