I recently bought the Mojo out of curiosity. It was a dealer's demo unit. It's in like-new condition. It looks like it has not been used much at all. The USB cable is still in the sealed plastic bag.
I have used it for about 10 hours and have charged it a couple of times. This is a very powerful DAC/amp portable device. The sound is rich just as many reviews have praised. However I don't really have a need for it. So I would like to sell it or trade for a pair of nice IEMs or a decent DAP.
