For the price of the product it's great.It will get your Eq close enough you can finish by ear.

So if you use have ever used your room correction/calibration with your Surround sound reciever you understand that it makes a world of difference.. but the truth is the calibration mics provided are often a place manufacturers cut costs.. to get the most out of your automatic room correction get this little mic and a trs microphone extension cable.. use this instead and it will capture your rooms reflections much better.. leading to a surprisingly good auto room correction..I have used with AccuEQ and Audyssey and and Ace

at least most women agree (i hope).all jokes aside, I've used this thing to equalize my LS50 meta and pair it with a SB-2000. It's done well so far and the measurements exactly match the ones others have posted online for these speakers, down to 20hz, except the bass gives slightly more jagged results.I've bought japanese microphone capsules before (for binaural recording) that are $5 each that have a flat FR. I also had a old UMIK-1 that broke (my fault) so i opened it and found a 1cm capsule sitting at the nose. I'll try to fix it so i can compare them. so it's not about the size, it's about the quality of the capsule.

This really works to specks and nice price.

I have been using one of these for years. Then I upgraded my phone and tablet to Samsung Android devices. Uh-oh, no headphone jack. I started out with one of the inexpensive usb-c to 4-pole headphone jack adapters. I could not get it to work, until I discovered the trick: you have to plug in headphones to get the adapter (actually a dac and adc built into a connector) to turn on. It worked, but SQ was not great, and dragging around headphones just to activate it was a pain. Then I tried the RDE AI-Micro usb interface. That thing worked right out of the box. Now I can do impromptu testing of live band sound, room acoustics, sound system behavior, etc. I am using the Sound Spectrum Pro App, which has an RTA mode that can run at 1/24th octave resolution. It is an amazing combination.

I lost my first one in a move. I love these, very compact, very sensitive, does a nice job. I use it primarily with their software and in conjunction with system/speaker tuning.

Great item for how small and compact it is.

Great mic for audio system measurements in your listening room. Calibrated inherently to within 3 dB from 20 Hz to 20 kHz. A cal file is available to download from the manufacturer for each unit. Plug into a headphone jack on your iPad (if it has one otherwise you will need to use the Apple connector and an adapter). Works great with a real-time audio spectrum analyzer app. I use FFT plot, great inexpensive app.

Connects to any audio device that has a headphone jack

Great little microphone for measuring your stereo system for accurate equalization with something like Room EQ Wizard. Easy to get the calibration file from Dayton Audio's website and put it into your RTA software. It's the only one I know of that can be used on a laptop or phone that has only a single 4-pole 3.5mm jack and allows you to plug in your AUX cord to the side of it to forward on to your receiver to play the test tones while doing the measurement simultaneously. Others you'd have to buy a splitter or have 2 separate I/O jacks. It also has a nice wide frequency response of 18Hz-20kHz, so it'll be able to pick up the lowest of lows and highest of highs. Looking forward to doing to full analysis on my truck's stereo as I used it on my home theater system first to get the hang of things. Just don't forget to download your calibration file for your serial number!

Easy to use probably not as accurate as the more expensive ones but will get your set up in the ball park

At no point in the description of this product does it tell you that the thing doesn't work unless you can find a software patch so the analyzer app will recognize the mic. Every thing you can find online about this product is at least 8 years old. The Dayton site you are directed to has no place to put the serial number to get the patch. If you are contemplating buy this. Take the money you are planning to spend and throw it in the trash now and save yourself the hassle of spending the energy of opening the box that this worthless junk goes in

Nice small, inexpensive solution for doing basic RTA work. I wanted to be able to test Frequency Response on my speaker home-builds, but I didn't want to invest a couple hundred dollars in one of Dayton's (or someone else's) mic and a PC audio interface. I figured this was worth a shot. I use it with my Galaxy S9, running AudioTool. The speaker output allows me to send pink or white noise, or music, to my bench amp and measure/record RTA data including SPL, 1/12octave slopes, room response, etc. It's accurate and consistent enough for my hobbyist needs. Note that without an anechoic chamber it's pretty much always going to register a constant 40 dB level around 50hz and down. This is normal, depending on your environment. Make note of your baseline readings and don't get thrown off if you think you're getting phantom low-end readings. Anyway, it's definitely worth the money and offers better than expected value for audio measurements.

I decided to purchase the DAYTON AUDIO iMM-6 MIC. My lifelong favorite hobby, of sorts, is messing around with audio electronics and speaker systems.I was using a similar sized condenser mic (Yamaha YPAO) which was included with my Yamaha 5.1 receiver. However, I've never been certain of the accuracy of the YPAO. It is made exclusively for the Yamaha receiver, and not for independent measurements.This DAYTON AUDIO iMM-6 mic, on the other hand, is made exactly for such a purpose. The iMM-6 comes with a calibration file which may be downloaded, for free. The file I downloaded is unique to my mic. To my understanding, Dayton Audio's lab measures the response of each and every iMM-6 mic (from 20Hz to 20kHz) and compares the response to a professional grade mic. All deviations are then logged into a calibration file, to be obtained by the user. This file is unique and may only be obtained via the unique serial number of my mic. This calibration file may be downloaded into an analyzing computer program or into an Android or Iphone audio analyzer app, or simply downloaded and printed.The mic itself is tiny, maybe 2 inches long. It arrives in a nice little metal box. Within, is a thick foam liner which safely holds the mic in place. It neatly plugs into the headphone/mic jack of most phones (your phone must have a TRRS jack, which allows simultanious recording and transmissions) .This mic comes with a female 3.5mm jack to which you may connect headphones (to monitor what you are recording) or connect to an amplifier input if your computer/ phone program/app is able to generate various test frequencies/ signals.As far as pickup sensitivity and overall performance. Sensitivity of the iMM-6 is def higher. As much as 10dB higher than my YPAO, depending on frequency. Since the iMM-6 mic includes the calibration file and is claimed to be accurate to within 0.5dB, my comparison of test signals has made me realize my YPAO mic is quite a bit off. Much more so than previously believed.So, I believe this little mic is well worth the $20. I am now ordering an extension cable (TRRS to TRRS, male to female), to allow more flexibility of use. Any such cable/adapter must be TRRS on both ends. TRS will not work. TRRS is a 4 conductor cable and connector.I prefer using my laptop over a phone because the phone's internal circuit does not allow for a flat 20Hz to 20kHz response, whereas my laptop allows bypass of the limiter circuitry.Highly recommended

Used it with the Elac Sub app.

This external microphone was one tested by NIOSH for use with their noise measurement software and performed its function extremely well and was such a bargain compared to other external microphones to be used with iPhones and iPads. The value at roughly $20 is certainly unsurpassed. Great for using with iPhone to record noise level in working environments. Microphone comes with an external calibration file which was easily downloaded from the manufacturer's website. An excellent bargain to perform noise measurement in combination with NIOSH SLM software (free)!

It works well and is easy to use. I use it with a Spectrum analyzer for Android to measure interior and exterior ultrasound to record the frequencies and decibel levels that deterrent sensors emit. I can't wait to use it with an application that can import the calibration tool for an even better accuracy.

Seems to work good. Used it with the calibration file to tune a DSP.

Was able to calibrate and use with audio tools to tune my car stereo

I recently added a JBL LSR310 subwoofer to my LSR305 speakers and needed to determine the volume level for the subwoofer. I used my Pixel 3a phone with this Dayton Audio iMM-6 tool and it worked great! Of course you also need to use your ears to determine what sounds best to you.
