          A GREAT Mic for soft voice
          This mic is great and just what I have been looking for. I have a soft voice and tried using hand held mics but couldn't get the volume up without worrying about feedback. With this mic I was able to turn it up so loud with no feedback at all that my band said that it may be too loud. My Drummer bought a wireless head mic that he had to return because it would feedback before we could get the volume up as needed. I sat behind his drums with his drums miked and NO feedback at all. I'm sure he will be buying one of these also.
          The on/off mute button on the belt pack comes from the factory as a temporary off, like for a cough but it can be changed to a temporary on or as an on/off switch which I prefer. It was VERY simple to change.
          The headset could not be any more sturdy or it would be too heavy to wear. I give it a Five Stars because it works for me and my soft voice. No more worrying about feedback or getting it loud enough to hear me.
          It is GREAT for a Rock Drummer who needs to be loud without feedback from his other mics or monitors and for anyone with a soft voice that needs a lot of volume from a mic. Someone did it right with this one and now they need a handheld mic with the same Cardioid Condenser mic. Thank You for a Great Product. I also recommend this headset with a Shure wireless System for anyone who needs to move around such as a singing lead Guitarist.

              I play hard rock/ metal type music and play lead guitar so I wanted this for the anti-feedback technology that is exclusive to Crown mics, and this one was designed with the needs and input of an acoustic guitar playing singer (Garth Brooks) in mind.The true bonus is the great sound of this headset mic. I own/ have owned Shure and Audiotechnica headset mics, the sound of the Crown is far superior to either.I haven't played it at any serious volume yet so I can't vouch for anything above me by myself in my home studio level but at that it works very well. It also came in a very rugged case made of a similar type plastic that is typically used with [...] Craftsman toolsThe only knock I have is the headset itself it is neither comfortable, or easy to fit (still doesn't feel quite properly secured) I realize the fit will vary per person. Tho opposed to the Audiotechnica which was immediately easy to fit and comfortable (but the sound tho is far below the Crown's however.)I do believe I will eventually bend the headset portion in enough ways to get it to fit my head well enough as bending it up considerably has helped immensely.That fit was/ is a pain in the neck tho.

              Though the product has very good sound quality, the screw that is supposed to hold the microphone assembly is stripped. While attempting to use it for the first time at a live performance yesterday, the microphone kept swinging away from my mouth and caused a tremendous problem. I will be returning it!!

              Comments about Crown Audio CM311A - Headworn Microphone:

              As a female singer with a delicate voice, I assumed I was destined to only be able to provide backup vocals when playing live. If I sang into an ordinary mic, we would inevitably get feedback from the drums and the soundperson would have to turn me way down, meaning I wasn't loud enough to be heard as a lead singer.However, I can now get the volume boost I longed for by using the Crown CM311A headset microphone. I gave my first live show with the new mic in June 2010 to a 1000-person audience. The soundpeople were especially happy with my "new toy" and were able to successfully adjust the vocals and get just the right balance for the very first time! My friends said they could hear me sing lead while rocking out on drums.The set also gives me freedom of movement. I use the hardwired model, but the wire goes down my back and does not get into the way of my arms, legs, or sticks while drumming.I'm so happy with the sound quality and freedom of movement, I have to give it 5 stars!A bit of advice:• Be sure to use a good quality balanced mic cable for the best sound.• This is a one-person mic and once one person uses it, it is their mic and their mic alone and can't be shared. Your mouth is right on the mic, so sharing is not sanitary. Also, you will need to bend it to fit your particular head shape.• This is a very delicate mic. Always store it back in the case when not in use with the velcro strips around the curved part of the mouth piece.• [...] A few small improvements could be made to make this product even more user-friendly:• I use the mic for practice by running it through a pre-amp and laptop, which sets the mic to the "on" position because power is running through it, even if the switch is set to "off." There's a way to reconfigure this setting by taking the mic switch apart, but I don't want to mess up the settings for live playing through a PA on stage, so I have to contort to hold the "mute" button down when I want to have a conversation with the rest of the band. A better switch design would improve this product.• Like most women, I have a small head and even though some portions of the frame can be bent to fit around your ears, it's still not the best fit and the frame sticks out behind my head near my neck and gets tangled in my long hair (which I put over the frame during live performances). If I wear glasses during practice, both can't fit over my ears and the headset begins to fall off. An improved frame design would make the product even better.
