Fantastic Mic

Absolutely a great microphone. If you need hands free this is your solution. Once adjusted (and just for you) it works perfectly. And I have to add that once again the performance of Sweetwater staff is great. I received excellent support and help from Dylan, thanks, Dylan, and from Jessie in tech support. Thanks, Jessie. You just can't beat Sweetwater.

The best!!!

I was expecting a good headset, but this Crown CM-311A blew my mind!! Easy to fit, no feedback at all, no drummers interfere with my singing even if we're side by side... Amazing silent on and off button, sturdy and comfortable. Highly recommended!!!

Working Musician

I have used this headset for the last 7 - 8 years. Absolutely love it.. By far the best mic I have ever owned. It is true the mic is delicate and should be handled with care.. I've gone through a few windscreens and have replaced the tightening screw once. I am happy to perform a little maintenance on it from time to time.. The thought of using another mic is not an option. This mic IS that good.

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.

Crown CM-311A Wired Headset Microphone

I purchased this headset after reading many reviews off the internet. I am more than satisfied with this headset.I have been a drummer for years and started singing with the group and was using a Shure SM-58 with a boom stand. As a drummer ,this setup was nothing short of torture because of always having inconsistant sound levels coming out of the speakers while singing and the stand in close proximity to my arm limited my freedom of playing . I found the quality of this set is very good and the voice coming out of the speakers sounds as good or better than the SM-58 due to the fact that the microphone is always at the same distance and there is no boomstand to carry around or get in your way. I have played 4 gigs and 4 three to four hour practice sessions with this headset so far and am very impressed with the 9V battery life with a good alkaline battery. I am still using the same battery that I originally put in to the pack.The only problem I had was shutting the headset off by the toggle switch on the battery pack..It would thump the speakers every time I turned it off. Fortunately, there is a fix for that . There is a switch inside the box that allows for the use of an on/off button which is on the power pack. Once you change it to the on/off button, the turn off speaker thumping problem disappears and it is a silent turn off .Headset is adjustable to most all head sizes and is light enough to not be a burden while playing . To make a long story short, I love this headset and would recommend to all drummers who have problems with boomstands and drummer freedom while playing .
