The headphone only paired with 1st generation iPad, not with iPad 3 and iPhone 5S, not even with Sony's own Vaio Duo 11 with Windows 8. After contacting Sony online support, the trick is to press the "POWER" of the headphone for more then 7 seconds to see the blue and red flushing alternatively. The headphone is now working fine. Thanks to the support.
I tried it and it works fine with my iphone 4 and mcbook air 2011 - after 7-8 seconds there is another sound a bit different than the one when you turn it on or off
