I was very uneasy about buying this headset but the reviews were great for it which convinced me to purchase it. I am very glad that I did. I use it with a Blackberry 8800 and people that I have told that I am using this headset have all said that it sounds better then when I just use the BB to speak. I can hear people on the headset even with my windows down in my truck and on the highway. Now of course if the wind is really strong I can't hear that well but that is with any phone.If I needed two or three I would choose this headset again especially for the price.
