There was a marriage, the right earpiece did not work out of the box, after 100% charging it worked for an hour and died again. If you compare it with a cheaper product from the same Sony, it will become quite sad. Sony SBH56 + Sony MDR-EX450H will cost about 4800, but will provide you with better sound quality and a stable connection, excellent passive noise isolation. Yes, there will be wires from the headphones, but this is not critical for everyone.
