The H700 headset has very poor reception. I was able to talk with the H700 but the static was absolutely horrible. I used this device for a two-week period, in a 100-mile radius of my home, and the phone was never more than 5 feet from the head set.I couldn't keep a conversation, as the words were broken. I used the device and drove over 30 miles in the Dallas area, the entire conversation was broken. I used the device in my home, full bars on my phone, the phone in my pocket, and have the same broken word conversation.The H700 has been in the trash for weeks now, and I don't think I'll purchase anything from amazon as I think everything is factory defect/reject and your company is selling junk that no knowing people will purchase.Tom Schultz
