Bluetooth MP3 Player 8GB KLANGTOP Digital Clip Music Player with FM Radio Voice Record Function Special Design for Sport and Music Lovers (Blue)

Whenever we start playing music the iLoop setting is on -- we have to go to play all again to get it to play more than 10 seconds, how can I fix this?

Can you use it to record from the built-in FM radio?

Does this have a headphone jack?

Can you turn Bluetooth off or is it always on?
