this is the second eclipsemp3 i have bought. the first one didn't last long it wouldn't hold a charge. the second one that i bought last week worked a few days and then it won't turn on or off only works if it is plugged into an outlet. that's not what i bought it for. i would like to use it to listen to while i walk. i like the eclipsemp3, i hope you can give me an answer to this.
