I purchased the Samsung WEP200 after returning a Motorola bluetooth. People could not hear me clearly with the Motorola, but could with the Samsung. The Samsung headset works perfectly. No problem hearing people and vica versa. The reason I gave it a four instead of five...I cannot keep it in my ear when I am walking. Okay while driving in the car, but just the motion of walking bounces it out of my ear. I tried the earhook, but it does not help. All I have to do is brush my hair away from my ear and it is dislodged. There is not really any clear directions on how the piece is suppose to fit in your ear...perhaps that would help. There is a picture of how the ear loop should look but no explanation for what part of the ear it is suppose to be catching on. Great bluetooth, but the ear piece design needs work.
