At the moment I am abroad for an internship. Will be back in February for a comparison :). Just to come back at the topic; after the hype, I feel that the OP3 is just an okay sounding device. For everyday use, I feel it just has a tad too much attack, making it that I do not enjoy listening to it too much. I would not buy it for its sound quality, but the headphone out is just fine.
