this gives me the confidence to try my hand at grinding my own beans now. And since im making a cold brew, which would be the same as a french press grind, this is exactly what I wanted.

Holy Krup! 🙏🏼

Brilliant video

Great video I would have used Sesame Street Count Dracula to count my presses😂

This is for how many grams?

this is the best tutorial ive ever seen these days. NO BS NOR ADs NOR FANCY MUSIC. SIMPLE AND LIT. Love it!

i see a dripper though...

Ahhh... a video that shows exactly what you want, without someone who enjoys the sound of their own voice too much... thanks!

Great! 12 presses produces coarse ground coffee for French press or Cold Brew! Thanks

A very important thing to remember: Impedance Matching. This is an electronics term and is about the total Ohms a microphone introduces to the GoPro. From what I researched the Impedance of the external microphone should be 2200 Ohms(or 2.2 kOhms) for the GoPro 3 and 4 models. So if you research the Impedance of the microphone before you purchase it, find those that are closest to 2.2 kOhms as possible. Also, fyi...if you attach an extension cord to a microphone, you just increased the Impedance. Let's say you got a microphone that has an Impedance of 2.2 kOhms to match the suggested GoPro's external mic impedance. Then you connect an extension cord to the mic...you just brought the impedance out of "match" and reduced the quality. The more impedance you add, the lesser the quality.

thx man , made me not to buy none of those...very annoying the lag , cant synchro none of those , is it a standard prob ?

What's with the box? It drove me CRAZY! Lol

I like this idea. For a drip maker using 42 grams of beans, I've been operating mine continuously for 6 seconds but with some shaking up and down during that interval. I think the pulse method you suggest would be more reproducible once the parameters of number of pulses and on-time for each are established by trial and error

Thank you for the awesome test

How did you eliminate the crackling and popping while using an external mic? I have the Audio Tecnica and when I use it with the 3.5mm adapter for the GoPro 3+ I get a constant crackling and popping noise.

Too coarse imho

Great vid, I'm also having the problem with the sound only coming out on the left side, I have a JK MIC-J 044 purchased from Amazon, any suggestions? I fix it in Final Cut Pro but I would love for the raw footage to have the proper audio.

Bored to tears ? Not at all, that's the king of test I searched ! just bought a Sony ECM-DS70P.

what would you recommend for live drums? I'm trying to do drum covers but I don't know which mic to get

Hi. I have the Jap Sony mic (Ebay) and the gopro cable but doesnot record in my Hero3Black. There is another cable option or what is the problem. I have also the Audio Technica ATR-3350 and works OK. Thanks for your help Octavio elmoan001@hotmail.com

Thank you for taking the time to conduct a simple but very informative video about the microphones. it definitely helped me make my decision as to which microphone I want. :)

thats for a french press?

Tks so much

Sharing good ideas I can add it is also possible keeping the case (the smaller 3+) and using external microphone/composite/power with a solution similar to this GoPro Hero3 + Black - DIY external mic adapter cable to fit inside case (waterproof)

Great review - Thanks

Thanks for the work! I'm sure many will take advantage of your video... good job MM

great audio out of the olympus ME-15 but it came through my left speaker only, and no i dont have them mixed up or on the wrong sides

You can edit it n make it run on both left n right

I have the mic your talking about at 3:23 n it sounds great just make sure it's closer to your mouth so it's louder

Nice video, thank you for the help! Zalmen ZM1 WIN!

2:07 Zalmen ZM1 3:05 Audio Technika ATR-3355 3:56 Olympus ME-15 4:50 Olympus ME-51S 5:52 Sony ECM-DS70P My favorite is the Zalmen ZM1

I like the sound of the Zalman. However, from what I understand, the Zalman is not a lapel mic. The only thing it can "clip" to is to another cord (like what's on a gaming headset). Is this correct?

I thought the Olympus ME 15 had the best sound quality overall. Great test, very helpful!

Olympus ME-51S No doubt! Great video !

The Olympus ME51S sounds like the best choice to me. It seems louder than the Sony and has less hissing.

Obrigado, me ajudou muito! Thanks, helped me a lot!

This is VERY HELPFUL! I've been doing some research, and couldn't find comparison nor could i find any reliable reviews on external microphones for cool HERO 3 gadget. Your generous video is REALLY helpful, and I hope you continue to put more! For practical use, my favorite choice is the Zalman as well, although the Olympus has the best quality, I agree with you that having two(2) separate audio feed can be a bit of work during active use. Thanks again!^^

the zalman won

Thanks heaps mate saved me a lot of mucking around. I appreciated your time.

I wish you could test these bad boys on a motorcycle hitting the freeway. I'm looking for one for future vlogs and fun videos. Yet, it's a great video and good comparison. Thanks for doing it! : )

like your joke at 2'08 :) lol

thanks for the video :) so am I right assuming that Olympus is 'louder' than Sony, therefore better? Does Olympus pick up too much noise outside?

I ended up with just keeping the Zalman. A close second favorite was the Sony unit, but I couldn't justify having another $50 mic that is only marginally better (and significantly larger) than the Zalman.

Thanks for the head to head comparison.

Which microphone did you finally settle on?

Very informative and helpful. Thanks. I am going with the Olympus due to the smaller size and what sounds to be better sound as well.

Very helpful

Does it make a constant hissing noise? Mine does with the GPH2

Hi Mdjorie I have the ME51s I just got it and have used it with my GoPro H2 and there is a sputtering hiss in all videos. Do you have any Idea why this would be happening? Yours sounds perfect.

Great vid, very helpful. Thanks for taking the time to post it. I bought the Olympus ME-51S thanks to your work :)
