This is the best wired earpiece I've ever used. It costs practically nothing, and yet the sound quality and comfort are superb. I had a Jabra one before, but the microphone was very quiet and I had to shout into it so my interlocutor could hear me. With this one everyone says they can hear me fine. It clips easily onto your ear and stays there securely.I would easily have paid $15-$20 for this earpiece, and it's only $3! Maybe I shouldn't say that too loud!
