Died after a nudge while in jack

I connected the device to my iPhone was happy of the sound and it died and stopped working after a nudge.

Chris Forsythe
Died after 3 weeks of use

I was very excited for this unit. It sounded great and was very easy to use. I did notice it ran quite warm but it seemed to be functioning well. Unfortunately after about 3 weeks of use it has completely stopped functioning.
