Looking for a bit more from your CB microphone? This Cobra 70 Series may be for you. With a heavy-duty, drop-proof ABS shell the microphone nearly asks you to abuse it just so it can show you what it can take. The nine foot HighFlex cord will reach within the cab or around the office. Yet, the best function on this microphone has to be the noise canceling, voice coil diaphragm which makes communication a bit more clear, essential to those of you who work in noisy environments.

What's in the Box
One HG-M77 CB microphone and a one year warranty.

I bought this hoping it would just be a decent replacement for my failing Mic (had to hold the cord just right for my old one to work).

I have this radio in a Peterbilt truck so it gets a lot of use, the radio is a 20 year old Cobra 29 and this is the fifth or sixth Microphone I have bought for it due to rugged use.

I have had several of the people I talk to regularly over the CB comment on how much better my radio sounds since installing this Microphone. In the past the only comments I ever got were people telling me when my Mic was failing or breaking up but after I replaced them nobody noticed anything special.

I have used the Barjon and the stock coffin Microphones in the past but this is my first noise canceling Mic and it is doing a great job.

Well worth the price!

I am running this mic on a SuperStar 121 Export Radio in my base and mobile units. Everyone I have contacted says the audio is LOUD and CLEAR. the price great and cobra is known to be one of the best on the market. The price is great and the performance even better.

The one I recieved is different from the picture. There is no led light. The 4 pin connector has a groove to fit in the right way to cb radio and the groove is slightly different so the fit is tight. The radios I use are a Cobra 19 & 25. I feel like calling Cobra. It works very good however. Voice clear.

I bought this after looking at the options and prices. I just wanted a new Mic for my CB. This one seemed to fit the bill, and seems to work well. I do have an issue though. If I touch the mic cable I get a bunch of static even if my squelch is maxed out. This is very annoying, but may not be related to the mic at all. Still looking into the issue.

Otherwise the mic has been great. It is a little on the cheap side, but looks and performs nice.

Good CB mic for the price. Purchased to use in a loader in a rock quarry, so the noise cancelling is a good feature. I can hear and understand the loader operator when he calls.

This microphone does not what the seller said it done. Good luck trying to get check a radio check with this mic. You'll be heating up the mic with your voice.
I tossed the mic in the junk bin. I purchased a ranger sra-98 and what a world of difference. No problem receiving a radio check from other cb operators.
Stay away from this piece of junk.
