I have never been up with technology. My friend always had music on his phone and was listening to it all the time. I wanted to do the same. Going into this not sure I came out very pleased. I have a M520 phone and I listen to music all the time now. It has loud speakers and eliminates background noises. I haven't quite figured out how to answer the calls because when I hit the button on he headphones my phone freezes up. I really enjoy them.
