So I will need to return. Yes, you can turn them up and they can get quite loud when the music is playing, but they are lacking in the low and frequencies. It would not power on any longer. I still have my Teva?s from when I was in high school (23 years ago). Will definitely buy again from this seller! These were recommended to me by a fellow nurse and im so pleased i got them! I have 2 pair so far She love it, clear sound, and with that Micro / TF card slot, you can take all your music on the go, it also has a build in microphone so it allows you to take your call, and just like any head piece, the sound over the call could be affect by the environment you are in, but not a big issue for me. Youll notice as a whole they just dont seem to satisfy any portion of your needs. Gene Hackman(superb) even Ben Stiller usually a pain to watch isnt out pf his depth usual quirky Anderson plot,dialogue all add up to an enjoyable watch
