About the sound, first I try I was very impressed with the bass it's very rumble in my ears, be carefull with your volume device when you want to put in your ears make sure you have turn down the volume. The stereo sound was very clear better than my last sony earphone. unfortunately the microphone quality is very bad, distance voice capture must be really close to your mouth and the recorded voice not good, I'm more satisfied with my sony earphone than this if about voice record quality.
One trick for new earphone to increase or maximizing the earphone sound capability is, some people said do to sets to maximum power your device volume for minimum 1 hour, but don't put the earphone in your ears. but, I can't feel the difference. maybe it will effect only on expensive earphone, but not bad to try.
