If you've been looking to get the Rode Wireless Go, you should also take into consideration
the Bietrun Wireless microphone system.
I have to admit that the Bietrun modules aren't quite as sleek looking as the Rode Wireless
Go and they're slightly larger.
But with looks aside, one of the biggest differences is the cost.
The Bietrun sells for $90 while the Rode Wireless Go is priced at $230.
Out of the box, the Bietrun wireless mic system comes with a transmitter and receiver as well
as a box of accessories.
Those accessories include a carry pouch, dual head USB-C charging cable, 3.5mm lavalier
microphone, instruction manual and audio cables for cameras and smarthphones which I'll go
into detail later.
On the front, the modules look exactly the same.
And it's the same on the back with belt clips that double as a hot shoe mounts for cameras.
But here you can see the differences with the receiver on top and the transmitter on
the bottom.
The cool thing is that the transmitter has a built-in mic so you don't always have to
use the clip-on lavalier microphone.
It's also nice that these units are extremely compact in size and ideal if you want something
lightweight for recording audio especially when the camera and subject are moving.
To power on a module press and hold the power button and the backlit LCD screen comes to
life.
Here you can tell this is the receiver with the initials RX at the top.
The transmitter will be labelled TX.
But I want to show you how to connect this to a smartphone so you can do it correctly.
First plug the Audio Out cable to the receiver.
This is the one with 4 sections on the other end of the 3.5mm plug.
On Android and older iPhones with a headphone port, this plug goes directly into the headset
jack.
Newer iPhones without a headphone jack will need this Lightning to 3.5mm adapter.
Android phones without a headphone jack will need this USB-C to 3.5mm cable.
With these adapters, I'm basically adding a headphone jack to these newer phones.
But keep in mind that these adapters are sold separately and not included with the Bietrun
wireless microphone system.
If you have a newer phone, start again by plugging the audio cable into the Bietrun
receiver with the RX initals on the display.
On iPhone, plug that cable with 4 sections into the end of the Lightning adapter.
Then plug the Lightning adapter into the iPhone.
Finally plug the lavalier mic into the transmitter and all the connections are complete.
For this iPhone test I'm using the free Recorder Plus app from the Apple App Store.
I like this because I can see what input the phone is using.
And when I start recording you can see on the audio meter that the phone is picking
up sounds from the Bietrun wireless microphone.
Remember Android phones without a headset jack will need the USB-C to 3.5mm adapter
which is sold separately.
But for this Android demo my original Google Pixel does have a headphone jack and I've
got the Bietrun receiver plugged directly into the phone.
But if you want to record video on an Android phone with an external mic, you may have an
issue which I'll explain a solution towards the end of the video.
Connecting to a camera like a DSLR is pretty simple and straight-forward.
For this I'll need the 3.5mm audio cable with 3 sections on both ends.
Plug one end into the camera's microphone port and then plug the other end into the
Bietrun receiver.
Now there's a cool thing I need to show you.
The belt clip actually fits onto the hot shoe mount on top of the camera so the receiver
doesn't have to dangle by the cord.
Finally plug in some headphones here if you want to monitor realtime audio.
So those are the basic connection instructions for smartphones and cameras.
But Here are some audio tests so you can hear what the Bietrun sounds like.
Ok, so this is a quick test of the Bietrun wireless microphone system.
I'm using just the module itself.
It has a built-in microphone and I want you to hear what it sounds like and what it can
sound like.
And in just a moment I'm going to switch to the plug-in lavalier microphone so you can
hear the sound vs the built-in microphone.
Ok so now I've switched to the clip on microphone.
This is the wired lavalier.
It's also plugged into the same module that I was recording on before.
Except this time I've got the cord in this.
I just want you to be able to hear the difference between the built-in microphone and this wireless
lavalier.
I'm also recording on an Android phone just so you know source I'm recording to.
And forgive me for the shakiness I'm using this on a little short selfie-stick so this
is the Bietrun wireless microphone and I hope you can hear the differences between the two
mics.
The built-in one and the corded on here.
And now just one last clip here.
This is the phone's built-in microphone.
I've got it on that selfie-stick again at an arms length about as far as I can reach
out maybe about 2 to 2 and a half feet away from me.
But I just wanted you to have this for reference when you hear the differences between the
microphones.
And before you buy, here are some important things you should know.
The Beitrun wireless microphone system has a range of 164 feet or 50 meters.
And there are up to 50 channels available to avoid interference.
The transmitter and receiver modules can run for up to 5 hours and it takes 3 hours to
fully recharge.
And speaking of recharging, you can charge both modules at the same time with the included
dual head USB-C cable which is pretty cool that they included that type of cable.
And here's a really important tip for Android users.
Most camera apps that come installed on Android phones won't recognize an external mic.
And a lot of people get frustrated because they can't figure out why it's not working.
But my solution is to download the free Open Camera app from the Google Play store.
You should be using Open Camera if you want to use this or any other external mic during
video recording on an Android phone.
You'll thank me for this later!
At $90 the Bietrun Wireless Microphone System is a really budget friendly alternative to
the more expensive Rode Wireless Go.
