I am new to this but have done much research on the subject and the devices available. I have just purchased a CB6000s and have been wearing it for a couple of days I have been trying out the different parts to see what is most comfortable. My wife of 28 years does not know about this and I am sure would not approve.
You'll never know what she might approve of. I would have never thought mine would, right up to the point she snapped the lock shut.
