Question

I have a couple of Chinese ipod shuffle (clip on) knock offs. One will play song for 1o seconds and then switch to next song.The second one I have I am having trouble turning it on. When I switch it on, it doesn't come on immediately - maybe I'm pressing the play puase button too many times?????
