Hello everyone. Lurker here for a long time.

First of all, I love this forum, and all the customizations to my Xiaomi Yi camera.
As an introduction, I am a tinkerer by birth, and I open everything I own to learn how it works or make it better. Toys, tools, electronics, laptops, my 4 cars, software, car diagnostics/tuning/coding/programming... you name it... I probably have messed with it. Humans are next .... LOL (Med school graduate)


I have taken my wonderful XiaoYi everywhere (underwater/ziplining in Maui, under my racecar, etc..) and love the quality video it can provide. However it was lacking one thing, quality sound. When there are very loud sounds, I am sure some of you have noticed, it records very strange static/clipping noises. I noticed this the most while filming my car's (loud) exhaust.

So I looked around, and found someone selling the microphone from the GoPro HD Hero2, which looked like the right size.


Well today it arrived! No more further delays:

Size looks correct... (black one is XiaoYi original. The white one is GoPro donor.)

and reassemble.

Result is massive sound improvement. High pitched sounds and low, bass sounds.

I will be uploading comparison sound clips in just a little bit.

Here is a soundclip extracted from the video. I recorded a sound being played on my sound system, cranked up quite loud.



First 36 seconds are with the original microphone. I was moving camera around, to the small speakers, and to the sub.

After that, the next minute or so, it is with the GoPro microphone. I moved the camera around to the speakers and right next to the sub at one point. Very dramatic difference.

The video consisted the camera being placed right into the speaker cloth mesh, so there isn't anything to see really.

But I did focus my lens just slightly and it is sharper, so that's nice.

The original microphone is ~7mm diameter x 3mm thick. It may be difficult to find a quality replacement, which is at least better than the original one. If you look through ebay you will find one.

Thanks, I put in the specs I was looking for into digikey and found this guy on ebay.

I ordered the POM-3535L-3-R.

Plan is to wire a 2.5mm external mic inline so I have the option between the two. I think I'm more excited to mod it than to use it...
