I think the Coles 4104 Commentator's Ribbon Microphone is the best noise cancelling microphone around. It will cut out lots of background noise and be used in areas where everyone around you is wearing ear defenders. Its down side is that you have to change the way you deliver your script if you want to sound half decent On-Air.

Getting the best from a Lip Mic

The Coles lip mic, in its current style, was designed by the BBC and used for the recording of commentary in noisy surroundings by cancelling out a considerable degree of background noise.

The Benefits: They can be used in the edit suite, at the football match or in the news room, without picking up much of the background noise. This makes it possible to change your script to fit the pictures rather than having to rely on your first attempt recorded in a voice booth.

The Problems: The audio quality is poor. The microphone flattens your voice and removes the colour from your delivery. The low output level means you may be asked to deliver your script much louder then you feel natural. The microphone is very delicate and needs to be treated with great care, despite it looking as if it is built like a tank. With age and abuse the microphone becomes very prone to popping on "P" and "B" sounds. (Breath plosives)

Using the Microphone: Just lightly rest the spacer bar on your top lip. Don't press it on to your lip or your voice will sound as if you are holding your nose. Don't ever be tempted to move the microphone further away from your lips as the noise cancelling characteristic of the microphone will ensure that your voice level will immediately fall to an unusable low level. You will often get a better performance by standing up and holding your script out in front of you, rather than sitting down, leaning forward and compressing your diaphragm.

The way around the problems: The only way to put back the colour in your voice is to add a lot more when you deliver your script in the first place. You will need to "over act" and "over enunciate" your script. You will need to speak loudly and very clearly to prevent your delivery sounding muddy. If you or the microphone you're using are prone to popping then you may need to rotate the microphone so that the wind shield is at an angle of about 45 to your lips. This way your breath (the cause of the pop) will be deflected across the wind shield rather than into the mic. In the worst case, the microphone may still pop. In this extreme case you may need to rotate the microphone 90 , but always make sure you are still talking into the front of the mic. If you talk into the side of the microphone it will cancel your voice out almost completely! If you are worried about catching germs and colds from the microphone then washable hygiene screens are available for the front of the mic or carefully clean the mesh with telephone sanitising pads.
