Overview

The CM-311A is the latest version of the Crowns proprietary Differoid technology. Differoid stands for differential cardioid. Its cardioid pickup pattern rejects sounds from the rear, such as floor monitors. Its noise-canceling ability also rejects sounds at a distance, such as instruments on stage and crowd noise. This results in the CROWN CM-311 having outstanding gain-before-feedback and isolation. Controlled field tests showed that the Differoid provides up to 12 dB more gain before feedback than conventional cardioid microphones. Many users of the Differoid say that their house mix is better because the mic's isolation is nearly complete.

Designed for touring and live-sound applications, the Crown CM-311A is a rugged head-worn microphone with unequalled performance. It sounds like the best handheld microphones full, clear, and distortion-free, even with the loudest singers. Lightweight and comfortable, the mics headband and boom adjust to fit any singer. An included pop filter greatly reduces breath noise and pops. Because of the booms unique behind-the-ear design, it does not cover up the singers face.

Consumer Alert:

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.

For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.

I'm the singer/drummer in a four-piece garage band playing classic and contemporary rock. I had a good-not-great headset whose condenser was underpowered and couldn't cut through the mix.

Frankly, I looked for what Justin Bieber uses (just because he's the one singer who came to mind using a headset), found the Crown 311 wired unit and did my research. Though a bit pricey, I took a leap - and haven't looked back.

The sound immediately proved the price worth the investment. It cut through the mix and revealed depth and tonality that my now-back-up headset just couldn't deliver.

My only complaint is that the mic needs to be almost if not touching the lips to get the best sound, and the "boom" on which the mic lives cannot be anchored in that position. So when it strays, I've developed a deliberate and visible twitch to shake it back to my lips (you'll sometimes see singers with this mic touching the boom to put it back into place). I'd like to fix that, but if that's the only issue, it's one I can live with.

PS: I swear the mic is the ONLY thing I have in common with The Biebs (maybe I'm more like Phil Collins), and I promise not to spit on fans, race a rented Ferrari down Miami Beach, or generally be a jerk.

Great sounding mic high quality condenser. My only problem with this mic is where the mic attaches. The plastic housing is real fragile and will break easily. It will not survive any kind of drop or stress the mic's plastic housing will break. I am surprised at this poor design and quality, because every Crown product I have bought has been bullet proof. The hard plastic storage case it comes in is pain for storage and has no padding period. I was able to repair mine with JB Weld the original stuff. It is now stronger than ever. I would not buy this mic again.

Great sound! Needs to be more adjustable.

Comments about Crown CM311 Headworn Condenser Mic:

I am a singing drummer in a Blues band. I was very frustrated with using a SM58 on a boom as it seemed it was always in the way. I researched head worn mics and found the best reviews were for the Crown CM311. I purchased the XLR model and plugged straight into the board. The sound is amazing! Booming lows and crisp highs with a very high threshold for feedback. One of the downsides I read in reviews was that the headgear is not adjustable enough and tends to slip. I found this to be true, especially mid-gig when my head was drenched in sweat. There is no way to tighten the headpiece though I discovered I could tighten the right earpiece which helped considerably. I spoke to my band mates after the show about the slippage. One of them asked if I would return the mic. I said that with a sound like that I'm keeping it if I have to duct tape it to the bald spot!

    Comments about Crown CM311 Headworn Condenser Mic:

    My only beef was that I wish I would have known more about the repairs that this mic needed when I bought it. I could have facilitated a quicker turn around time from the workbench to the stage, but you know what? Putting this mic back together was a VERY cool project. I've ALWAYS had good experiences with Musician's Friend and this purchase was no exception! They say all good things come to those who wait... The time it took for me to get this mic up and running was well worth the wait! It's an awesome mic (even if people say I look like Madonna) and I have no regrets whatsoever! The wife grounded me from using my credit card though... It was so worth it!!!

    Comments about Crown CM311 Headworn Condenser Mic:

    I bought this as a used item. I rarely buy used gear but I needed a new mic and I've always had my eye on this model. The value was great and it shipped directly to my door (duties and taxes paid) here in the Philippines, so that was another reason why I decided to buy it.

    The condition listed was 4 (needs repair). My ONLY beef was that the listing could have been a bit more specific as to what kind(s) of repairs it needs. I had to find out the long way and thus, have to buy the parts to fix it. It'll be a few more weeks before I can actually use it because I still need to buy a wireless transmitter and receiver that is compatible.

    It sounds like I'm complaining but I'm not! I thought all of this would be a pain but not in the least! I'm actually ENJOYING this project. I've been in contact with Crown Audio and Shure in putting this back in working/roadworthy order. Both companies have been VERY patient, cooperative, and accommodating. I can hardly wait to get this mic working! It's taking A LOT of hurry up and wait as well as elbow grease, but like I said, this is frigging awesome!

    Comments about Crown CM311 Headworn Condenser Mic:

    I am a profession drummer and percussionist. While playing drums I use the hardwired Crown CM311 and a wireless one when playing percussions as I move around a lot during performances. I've used Countryman and AT wireless mics before and the Crown is the most versatile of the three. Much less distortion than the AT with less feedback problems than the Countryman, although I think the Countryman mic sounds a little bit clearer. I was first aware of the Crown CM311 when I saw Michael Jackson using one but decided to buy one after seeing Garth Brooks using one. What impressed me is that there was a bank of floor monitors the whole length of the stage and Garth was leaning right into them with no feedback problems. These are very good mics but the few problems that I have with them is when I sing loud there can be some distortion. I've fixed that problem by using the pad on the PA for my wireless and I use a inline attenuator (AT8202)for my hardwired Crown. Using the pop filter also helps. The only other problem is working the mic. As with all head-worn mics, it is hard to back off the mic when necessary. I also handled that problem with my inline attenuator that, with a click of a switch, allows me to turn my hardwired Crown mic down an additional -10 or -20 dB's. With the wireless I run a A/B footswitch from the receiver and run to two channels on the board both set the same except one set for lead vocals and another set for background vocals. I know that these ideas calls for extra equipment and setup time but if you're going to use any head-worn mic these are ideas you can use if there are problems. For me, with these ideas and proper eq, the Crown CM311 can sound as good as any dynamic hardwired mic.

    BEST HEADSET EVER!!!

    By K.T. Tyler

    from Baldwin Park

    Comments about Crown CM311 Headworn Condenser Mic:

    I've gone thru several Headset Mics, with the Crown 311/AE being the LAST. I've had people tell me that I look like an Airline Pilot and such, until the y heard my Mic. Now I don't use ANYTHING if I can't use my Crown. I have used my Crown CM311 for MANY different Styles of Music in almost every kind of venue around the World. Form Vegas, to Chicago, NY to LA (Where I live now...) Rock, Jazz, Hip Hop, RnB, Blues, Country. You name it, THIS headset can handle it. It's also Light and Sturdy. And Feedback is Non-Existant. I've been close to Side Fills, and in House in the Crowd right next to the House Speakers. I have had this thing INCHES from the Monitors in several arenas... NOTHING!!! And, my Voice is always pristine and Clear. (Sometimes I don't know if that's Good or Bad... lol!) Makes it very easy to Mix into the House System. I have the Older model from 1996 (with Twin earpieces). So I'm looking forward to getting an upgrade to the New SINGLE EARPIECE Model as shown here. For those of you looking for a FANTASTIC Headset unit, PLEASE look no further than THIS ONE!!! (I use mine with the Shure Systems Plug. You can get different plugs depending on what Make you go with for a Transmitter/Receiver... So, whatever Make you go with, be sure that you get the plug that matches the unit!!! If you get a Sennheiser Wireless, make sure you order the Crown with the Sennheiser Plugs, etc...) You WON'T be disappointed. One of the BEST INVESTMENTS I'VE EVER MADE!!!

    excellent deal

    By Kristian Thompson _

    from Rio Rancho, NM

    Comments about Crown CM311 Headworn Condenser Mic:

    As a drummer, I have tried using boom mounted mics. The best, Shure SM58. the mic is great but as a drummer, always having something jammed in your face while trying to play is not only distracting, I was constantly hitting the mic and boom with my sticks. I had tried a head worn headset made by audio tech but it kept feeding back and sounded VERY thin. My wife complained about it sounding horrible. I found the Crown CM-311A on GC online store, used. It was a great price so I gave it a shot. the very first night I used it my wife asked me after the gig if I had gotten a new mic. She said it sounded terrific and that she could definately tell the difference. Numerous gigs later I am still using it and with great results. I can wail away on the drums while I am singing and it isn't in the way and I am free to move about and not have to worry about being right up on a stationary mic. I would highly recommend this mic, especially for drummers.

    Comments about Crown CM311 Headworn Condenser Mic:

    Do not try to use this product unless your band has its stage volume well under control, OR you are using in-ear monitors. Not suited to heavy rock music. And the high end reproduction is also kind of muddy, so I found that when I was really belting, there was a little distortion.

    freedom

    By kristian thompson

    from Rio Rancho, NM

    Comments about Crown CM311 Headworn Condenser Mic:

    As a drummer/singer, I had originally used an Audio Technica wireless mic (forget the model) but sounded so thin and kept having wireless dropouts. switched to Shure SM58, which helped in the full sound area, but with a honking mic, boom and cable all in your face, very hard to be a good drummer. constantly hitting the boom/cable/and or mic with the sticks plus you just didn't have the freedom to move around. plus the mic in your face just is very distracting. I picked this mic up (CM311a) from GC online, used at a very good price. I am very pleased with it. it takes a bit to get used to the head mounting system but once you do, what a difference this mic has made I am no free to blast away on the drums and still able to sing and talk as I need to. there is an on/off switch on the belt pack which is very convienant. the only nuance is that the mic picks up heavy breathing. I am considering putting a small piece of electrical tap on top of the wind screen just to squelch that. just a thought on that, haven't actually tried it yet. I got a comment from my wife on or first gig, she asked me if that was a new mic because it just sounded so much better than the old head worn one. she really noticed the difference. I would definitely have to say that this thing sounds every bit as good as the SM58 that I was using. now that mic is freed up for my guitar player to use. I was getting a lot of feedback issues with the SM58 also, not so with the Crown. Very satisfied with it so far.
