THESE HEADPHONES ARE REALLY ONLY ALRIGHT FOR LIGHT USAGE.THEY ARE EASY TO INSTALL,AND THE SOUND QUALITY IS OKAY,BUT THERE IS NO WAY TO AMPLIFY CONVERSATION AND OVER TIME AND WITH CONTINUED USE THE VOLUME HAS DECREASED. I WOULN'T RECOMMEND THEM FOR OFFICE USE AS THEY DON'T HAVE A PRIVACY BUTTON EITHER.
