The Audio-Technica AT831B is a miniature cardioid lavalier microphone with a sensitivity and frequency response suitable for professional video, broadcast and sound reinforcement applications. The cardioid polar pattern is effective minimizing off-axis signal, providing high gain-before-feedback while using nearby monitors and speakers.

The wide frequency response of 40Hz to 20kHz enables audio signal to be reproduced with accurate detail and minimal noise at low frequencies. The miniature capsule enables the microphone to be hidden underneath clothing and the included windscreen protects against noise caused by plosive signals and wind.

        Comments about Audio-Technica AT831B - Mini Clip-On Mic:

        i am a legal video specialist and need a rugged wired mic that rejects background noise and delivers clear crisp speech. I have used the AT831b for nearly 20 years, and they get dropped, abused, yanked and spit on and give many years of good service. Once in a while I have to replace one, but I would never consider anything else for my work. I capture testimony that can never be re-done if anything goes wrong, and no excuses will be accepted. I can't say anything negative about this AT mic, it never disappoints. I haven't used it with a guitar, but I have used it as a musical soloist, and it is great for that too.

                  the sound of this microphone is warm and it has a good presence in the low medium, It's a complementary solution to other more aggressive products of the market.
                  It can be used in noisy conditions.
                  Its construction is robust and the manufacture of very beautiful quality
                  The battery power supply solution is useful

                  A good lavalier for the beginning user. A goodlav for the presetup shoots. This not a easy mic to setup quickly since it is not wireless. For being a wired mic I wish it was a little cheaper.

                  This microphone works well for my purposes - video interviews. The sound is clear and fine. However, be cautious with the metal clip on the back of the power pack. I cut myself twice on it (beware extremely sharp edges on hole in middle of clip) before I realized what the problem was. I taped over it with duct tape to get around the problem.

                    I got this as I have a few client videos coming up and want to get a mic right up on them cutting out room noise. Being a directional style mic, it's a bit larger however I find it still sounds quite good and really keeps room noise out well. The price is another thing I like about this product. It's affordable and sounds decent, what more could you ask for?

                          I am recording voice between actors in a room with too much air conditioning rumble. The AT831 pick-up pattern has been a good tool for improving the voice-to-rumble ratio on my videos. That means I have to do less post-processing on my audio tracks.

                          The power box seems larger than it needs to be - I run wired using phantom power over the XLR connector, so I don't need the battery.

                          AT could also improve the lapel clip a bit - perhaps make the alligator a bit wider? - so that it is more likely to stay where I put it.

                          I tend to be kinda rough on gear - I've already dropped the microphone capsule a couple of times - but it's surviving so far.

                            If you're looking for a good lavaliere microphone for interviews or other up-close audio work, look no further. I have used this microphone extensively, from applications ranging from television broadcast to music production, and it always does the trick. I honestly have no reservations about this mic.

                            Totally what I was looking for with crisp clean audio. This is not a problem for me, but if you are looking to hide this mic on someone's collar, think again. It is about the size of a marble.

                            If you don't care that your mike shows in your interviews, this is the perfect mic for the price.

                                The Cardioid Condenser Lavalier Microphone from Audio-Technica has allowed the Patriot League to produce high-quality video features with crisp, clear interviews. The microphone does a great job at singling in on the interviewee so that any background noise will not interfere, even in loud arenas or outdoor venues. It is easy to use and effortless to set up.

                                We will use it with all of our web streaming programming, including feature interviews and periodical online shows.

                                Comments about Audio-Technica AT831B - Mini Clip-On Mic:

                                I'm using this microphone as an input on my Zoom H4N handheld audio recorder and am very happy with the quality of the sound I'm getting. I'm also very happy with the level of isolation from background noises that this microphone give me.

                                The microphone and power module come in a smart hard-case which is very welcome when the unit is in my gear bag though the power module is metal and does not come with any slip case so I'm slightly worried about it falling off my interviewee's belts and smashing if it hits a hard-floor.
