A real pleasure to listen to songs via the headphones, you can modulate the sound to avoid the ears suffer. Very easy to set up. I did it with my iPhone 4S and my Samsung Note 3. Carefully read the instructions (in French) to prevent errors. It may well answer the phone while listening to a song. After finishing communication, pressing the phone button, and the music resumes. We can go from one song to another even if the first is completed. Nothing to say. Very well thought out. I delighted with my purchase. A buy eyes closed.
