I have heard about these headphones on jtgeek. They are beautiful, well finished and the package is really original BUT and yes there is a but. With a Samsung smartphone (Note 2) there is a little game in the jack that produce little interference when touching (I did not say graze) the connector. I had never encountered this type of problem with other headphones or intra oriculaire. Now the sound quality is quickly forgotten this very slight defect.
