CNET has a review of the Bluetake BT400GL and writes - “However, we were quite disappointed with the audio quality–while we could hear others just fine, callers repeatedly had to ask us to speak up, and they said we sounded faint even though we were speaking in a quiet room. The situation was worsened on a busy sidewalk and under windy conditions, as we struggled to hear our callers’ voices. Features of the headset are fairly standard. There’s answering, rejecting, and ending calls, last-call dialing, voice dialing support, and transferring calls from the headset to the cell phone and vice versa.”
