Oakley Thump Issue/ MBP eject problem

[zblaxberg]

I have a pair of oakley thumps...they are the sunglasses with built in mp3 player...Whenever I plug them into my mbp through a usb cable, it pops up on the desktop so I can drag and drop songs onto it. However after a minute or two It automatically ejects itself and says this device was not put away properly and some information may be lost. What can I do so that I can transfer songs onto it without it ejecting itself. (Yes these songs are coming out of my itunes library)

They probably shut themselves down after a few minutes. I'm not familiar with the the product, but the only way to mitigate the problem might be to add songs and eject it right afterwards.
