The Boom headset is expensive but worth every penny. I have tried many headsets and this one's way ahead of it's competitors for killing background noise. No other headset microphone is even close. This thing is easily heard by people I am talking to on my cell from very noisy locations - family, friends and associates can't believe it, and appreciate it. Talk in a low whisper in a loud environment. Like having your own mobile "quiet room" in busy crowds, noisy restaurants, on the open road, in loud conferences.Just got the new v4 Boom, and its lighter and more comfy than the prior model which I constantly used for over two years. But I miss the convenient 2-piece magnetic connector boom.
