Zoom M3 MicTrak: Awesome but… there are some ZONKS!

[@hecjvaldez]

At 9:54 actually the non recargable build in battery is better for the environment coz the mic will not become obsolete in 10 years like smartphones do. We can use rechargeable AA batteries with this mic to not generate much waste. Great video by the way. Thanks a lot for this review!!!

Yes you can buy rechargeable. I don’t know why 18650 is not a standard user battery. You can buy chargers for 18650 cells so why not accept them in devices?

[@AbsurdImprobability]

You can power it with the usb port and a power bank. Having an option for AA batteries is a bonus not a zonk. You can even use rechargeable AAs. No LCD is not a problem, but it could use a file selector but you can connect to pc or swap the microSD. But for what this mic is, at this price.... I want a fleet of them.

[@Ozpeter]

Test of the 4 mics - well, exact positioning can make a significant difference but the M3 seemed to have the best sound in this test. I'd conclude that it's certainly no disaster, and possibly surprisingly good. 4:35 - the cable should be routed via the two little clips on the side of the mount to reduce handling noise. Maybe for this shot you didn't bother, of course. Rechargeable - well, many A/V people prefer to be able to put in fresh, commonly available batteries rather than experience loss of power when something rechargeable goes flat when you are miles from anywhere. Or use your own rechargeable batteries. Personal preference I guess. The demo of the 100 foot recording is impressive - not least because of your expertise in maximizing the final sound quality! What is encouraging is that the analog side of the device - the mics and preamps, before A/D conversion - seems to be commendably low noise. 32 bit float will happily record and reproduce such noise and it will get amplified if you crank up the digital gain in post production. In your extreme tests, ambient noise seems much more significant (which is inevitable) and analog noise seems remarkably low. That's good. The app is really not essential. You can process gain and stereo width in your editor. Voxengo MSED (free VST 'effect') loaded into your editor will do the width stuff (and more), and in fact, according to the theory of Mid / Side recording, you don't need to use the "raw" file for this purpose, if you have recorded with the 120 degree setting. It incorporates a load of other stereo field manipulations (eg channel swap if you've mounted the mic upside down, eg suspended above a concert hall). And a good editor would allow you to keyframe the width setting so that you could smoothly go from mono to stereo as required during the take. By comparison, using the app to process the audio first, then put it into your editor, is a clumsy way of working even if the app was really good. You've passed over four considerations in your excellent review. First, handling noise doesn't seem to be good. But in a lightweight device that's hard to avoid, and lightweight is good if you are using this on a gimbal mounted camera. Second, wind noise is very likely to be a significant problem - it's a shame they didn't supply a 'dead cat' wind muff. Foam doesn't do the job. As far as I'm aware, there's not one available (from Zoom) as an accessory even. Then, RF breakthrough. This I think has been noted by three reviewers that I'm aware of. The rest haven't had an issue with it. Maybe it depends where you are. Maybe it was a fault in the first production run only. It's certainly not in evidence in your tests, so that's encouraging. [I see you've commented on that to another viewer.] Lastly, the device can be used as a USB mic, while outputting to its recorder and to the line output. That's clever. USB mics can be used with recent DJI small cameras (Action 2 and Action 3) without needing any kind of mic adapter, so this is a handy feature. And of course you can record to phones or PCs etc via USB. Thanks for your hard work on this! It's probably cost me the price of the M3...

[@thepolishpotato42]

Wow, I am so floored! How does a video with 8 views get so much attention for a long and thoughtful comment like this! Thank you for stopping by and for taking the time to write this! "Rechargeable - well..." - I would agree with you 100% ***IF*** there was a way to tell how much battery power is left. The only way to do that is to follow the blinking pattern of the light(s) located on top of the device... what are we in the 80's?! Come on, Zoom! Since there is no easy way to tell how much battery power is left I would much prefer to have a rechargeable battery that will ALWAYS last longer than... let's say 12 hrs - as I can't imagine a scenario where I would need the mic running for longer than that in a single job. It seems like Zoom wanted to make this device as easy to operate as possible following the "set it and forget it" philosophy but this point is a little conflicting for me. You do have a point with the rechargeable batteries that you can swap - and I had another segment where I talk about it in the video but I cut it out - it was long enough, already. It is a solution BUT it adds another step in the workflow. My preference would be to connect a cable overnight and recharge the whole thing without worrying about the rechargeable batteries. "The app is really not essential..." - I was wondering about that but I thought I should be using the tool supplied with the product by the manufacturer as they would know best what will produce the best final result with their own device. I was also surprised that the RAW and the "regular" WAV files are exactly the same size. I guess I need to learn more about RAW audio. I understand the concept nad the process, just not the very technical details of how it actually works. You are definitely way more advanced than me and I'm not even going to pretend to have near the same level of knowledgel. I just like reviewing things and making videos about them :) If you are open to more conversation and wouldn't mind answering some of my questions please email me: [e-mail] "it's a shame they didn't supply a 'dead cat' wind muff. Foam doesn't do the job..." - agreed. I am not using one in this video but I used one from Rode Video mic on a job recently and it worked perfectly fine as it is almost exactly the size you'd need for this. "Lastly, the device can be used as a USB mic..." - Yes, it can and that is another awesome feature. I forgot to mention this in my review but I gave it 10/10 for versatility already so that covers it :) Thanks for bringing this up! "Thanks for your hard work on this! It's probably cost me the price of the M3..." - haha, thank you so much! I really appreciate all the feedback!

[@nictheartist]

You are so far the only reviewer who's done a voice test at various distances from the mic, which is what I've been looking for. Much appreciated. I take it that an indoors recording of, say 6ft, from the mic wouldn't be an issue to recover the audio?

[@thepolishpotato42]

Thank you! At 6ft you should be perfectly fine, given there is no noise pollution between you and the mic or any other loud disturbances around you.

[@Documentally]

I feel that Zoom have really thought this through. And question your Zonks. Removable rechargeable batteries are far better as the technology keeps changing. It also means that working in the field anywhere in the world you can grab spares. No screen saves batteries as well as keeps things simple. Stick a massive card in and you will have weeks of recordings. Also not an issue. I am glad that Zoom are focusing on the hardware and not the software. Software support is a nightmare as you will never please everyone. Thanks for the video. Honest but misled ;-). The 100ft test was an eye opener. But more because of Adobe's mad ML processing. Now that I have written all this I feel a little like I have been baited to do so. ;-) Good luck with the channel.

[@mq1995]

I actually think the M3 sounds better than all of those other devices you have around you, even better than the Yeti Blue which you switched to as your "default" mic. I have good headphones and I clearly hear noise in your Yeti Audio, and the voice is a bit muffled as well. The M3 recording in your video sounds absolutely clear with zero noise on my device, and the voice is much richer and crystalline.

[@thepolishpotato42]

That adds another reason why this is a good mic to purchase, doesn’t it?! I love the quality myself and if you check my earbuds reviews I actually started using the M3 for most of them because: 1. I agree, it sounds fantastic, 2. Ease of use, 3. Additional backup audio that never fails :)

[@gameroja]

Hello, good review! Some questions: when connected to the camera you need also to press the record botton of the Zoom M3 each time you start filming? Or when you press the start button of the camera the Zoom micro starts at the same time?. When connected to the camera the sound that comes to it is also 32bit? Thanks

[@thepolishpotato42]

Hi, thank you! Yes, you do need to press the button on the mic to start recording each time you start filming when connected to the camera. The mic has an internal recorder so the 32bit is only recorded into that recorder’s card. The audio signal is going to your camera so whatever the recorder in your camera does with it will be recorded on your camera’s card.

[@andrekart]

Very helpful. Thank you

[@thepolishpotato42]

So glad!

[@MattSpaugh]

TATER-MAN! Great video - I'm a F6 user looking for something to provide an on-camera backup for interviews, etc. I personally disagree with ZONK 1. I much prefer to have a replaceable battery. On too many devices if the internal battery dies on set you're sunk until that battery recharges to a certain amount (it's one reason I still love the Sennheiser MKE600). With replaceable batteries you have literally 5 seconds of downtime. As far as environmental concerns, you can buy rechargeable AA batteries. I'm with you on ZONK 2 for sure. I can see a Mk. II version of this mic with a screen. I'd add a ZONK - or maybe request two features. Timecode capability and something that would sync the record function with the camera. Having to press record twice and clap for each file would be a pain for run-and-gun work. All that said, your video was really helpful in my decision making and your production value is fantastic. Keep up the great work!

Wow! Great review, real world test, insights and tips, especially the Adobe Voice enhancer. As for the studio voice quality test compared to 'Broadcast quality' mics, the M3 in your test sounds very respectable. I like the M3's low end capture and warmth, but compared to Mics, and boards I worked with at a large broadcast radio & TV network, I'd prefer a bit more transparency and deal with the personality of the sound with live EQ and post compression. Having done ENG and run n' gun field recording, I much prefer AA battery operation and having a store of pre-charged high-cap AAs over built-in rechargeable so not to get stuck on location with a dead mic that has to be recharged. I do agree that an LCD that shows record time remaining and a function that would allow you to, split and erase tracks or format the card if needed.

9:39 Actually I prefer devices that have no internal battery, because I use researchable AA batteries, in this case. Any type you want and they last a really long time. You can have 4 or 6 with you when out shooting and change them when you need to. An internal battery needs to be changed in a few years and most likely the device needs to go into service to do so.

I have no issues after 2 weeks use recording to the internal SD. Your comments about the software is a little unfair. MS audio is not that complicated. The app does what it says. It’s only for adjusting the stereo image. I think it is assumed that you use a DAW in your workflow.

Is is that one review on B&H that you are referring to? I did not have this problem. We used the mic on three different jobs so far. One in a high rise building in center city Philadelphia, one at an animal farm in PA and one in a residential area jn MD. No issues with radio transmission interference. I can tell you this much: I use very high end, expensive lav mics by Audio Technica at my day job. They have excellent reviews everywhere you look and even those will sometimes pick up radio interference… and there’s not much you can do about it.

You can’t set it in the app because the whole idea behind how the mic works is that you don’t need to.
