    Picks up background noise and people complain they can barely hear me. Also the ear buds don’t retract. Very disappointed

      Hi Partyof4, Use a smartphone or mobile phone at least 50 cm(19 3/4 in.) away from the headset. Noise may result if the headset and the smartphone or mobile phone are too close.
      We appreciate your feedback and we will forward this to the proper department.
      Regards,
      Vincent sony_US
