Review: Samson Go Mic Mobile, first wireless microphone made for smartphone

Finally, there is a wireless microphone system that is designed to use with a smartphone. The Samson Go Mic Mobile is a 2 channel digital wireless system, that means you can connect two microphones at the same time. You can connect the receiver to your phone (or other device) via Lightning, USB (micro or C), or 3.5 mm audio jack. It uses 2.4 GHz wifi as a connection between microphone(s) and receiver. It’s easy to mount to your phone.

All this sounds so great, doesn’t it? So I tried the Go Mic Mobile for about a week. Watch the video to see what I found out.

For some audio examples of the lavalier mic in action, watch this report by Wytse Vellinga. To see (and listen to) the handheld microphone in action: the interviews in this report are done with it, and this interview is also recorded with the wireless handheld microphone.


  • It’s the first wireless system that’s made to use with a phone. Whoohoo!
  • The handheld microphone is not the best in the world, but it perfectly fine for most situations. But please, use a windshield. 
  • If you use it with a gimbal that doesn’t block the Lightning port (like the Steadicam Volt or Snoppa M1) you finally can have handsfree audio, even when using a phone without a headphone jack. So in many cases, you don’t need a tripod anymore. And it’s ideally for live streams.
  • It’s a two channel receiver, so you can connect two microphones simultaneously. And you can choose to mix the signal or pan it left and right (so you can use it as dual channel audio on your phone, yay!).
  • It works with iPhone (via Lightning cable) Android devices (via included Micro USB or USB-C cable, when using an app that supports USB audio), and also via any device via 3.5 mm headphone jack.
  • Pairing is very easy. Just hold the buttons and you’re good to go.
  • Various mounting options are included.


  • You can monitor the audio output via the 3.5 mm headphone jack on the receiver. But this only works for the microphone audio, not for audio that comes out of the iPhone. So if you recorded something and want to playback on your headphones, you have to plugin the headphones into your phone (when using a phone without a headphone jack that means unplugging the receiver’s Lightning cable). Also if you want to use the Go Mic Mobile at a live broadcast, you can’t use the 3.5 mm jack on the receiver to communicate with the studio.
  • To change the receiver mount, you have to unscrew two tiny screws with a small screwdriver. Those screws are not that durable, so it’s wise to buy some spare ones at a hardware store or online.
  • To get the Lightning port on the receiver at the same side as the phone, you have to mount the receiver upside down.
  • The handheld microphone has a lot of handling noise. So you really shouldn’t move your hand during recording. Also, there is some rumbling sound when you quickly move the microphone, for example between question and answer during an interview.
  • The standard gain level of the handheld microphone is too high. I had to lower the gain inside the microphone (there’s a knob near the battery compartment, including a screwdriver) to avoid distortion.
  • The range is not great, especially when there are concrete walls in between the microphone and receiver. Inside, I wouldn’t risk going more than 5 meters away.


  • Receiver + handheld microphone transmitter: 249,99 euro/USD
  • Receiver + lavalier microphone transmitter: 249,99 euro/USD
  • Extra handheld or lavalier microphone transmitter: 99,99 euro/USD

The receiver + transmitter sets start getting in stock in some places. The separate microphones are still hard to find.

Microphones, lights and other smartphone stuff at IBC

IBC in Amsterdam is mainly focused on the old-school broadcast world. But in between all those large cameras, studio equipment and satellite trucks I’ve found quite a few new mojo products. These are my pics from IBC 2017.

Note: I didn’t have the ability to test these products thoroughly. So buy at your own risk.

Expensive smartphone microphone.

Until now, microphones made for smartphones were mainly produced at that lower end of the market. But that has changed. German company Microtech Gefell presented their SRM 100 digital microphone. It’s an omnidirectional dynamic microphone. It comes with a Lightning cable and USB cable (+ converter for Micro USB or USB-C, depending on the phone you have). The sound quality is pretty good, it doesn’t have much handling noise. But the price is pretty high: about 600 euros (and it’s not widely available yet). Downside: there’s no headphone jack on the microphone or cable, so if you have a phone without a headphone jack, you’ll need Bluetooth to monitor your audio.

It sounds like this:

Sennheiser: Handmic and Focusmic

Talking about digital microphones. The Sennheiser Handmic Digital – that has been showcased at Mojocon for two years – should be available anytime now. It’s gonna cost around 300 euro, so that’s also pretty high end for an iPhone microphone. Sennheiser also chose to not include a headphone jack for audio monitoring. There is a version with Lightning connector for iPhone and a version with USB connector for Android.

Sennheiser also showed the upcoming Focusmic Digital. That’s a small shotgun microphone with Lightning connector. It’s -kind of- a competitor for the Shure MV88. I was able to do some test recordings with mojo guru Glen Mulcahy and we were both pretty impressed with the sound quality, especially the lack of background noise. It’s still a prototype, so things can change, but I expect that this small microphone will be good enough for vloggers and interviews in quiet environments. The Focusmic Digital will cost about 250 euro and should be available in spring next year.

Listen to this very interesting (ahum) story about my first mojo experience, recorded with the Sennheiser Focusmic Digital:

Another Lightning audio interface

Microphone manufacturer Saramonic will be releasing two Lightning audio interfaces. They are upgraded versions of existing analog audio interfaces.

The Smartrig DI (right one on the picture) has 1 XLR input, phantom power, a Lightning output and a headphone jack for monitoring. It’s a direct competitor for the Rode iXLR and the iRig Pro I/O. It should be available in a month and will cost about 108 euros. It has one disadvantage to the Rode iXLR: you can’t plug in a microphone directly, you’ll need an extension cable in between (just as with the iRig Pro).

The Smartrig+ DI has two XLR inputs, that can be mixed or separated onto the left and right channel. It’s a competitor of the iRig Pro Duo. Also available in a month. Price: about 180 euros.

Wireless microphones

Mobile journalists are still waiting for a truly good wireless microphone solution, ideally without a receiver, using Bluetooth or wifi. The good news is that the people at Shure told me they are working on something like that.

In the meantime, of course, you can use a wireless transmitter/receiver that is designed to work with a DSLR or broadcast camera. Another option is the all-new Samson Go Mic Mobile. Samson was not at IBC, but I’ll post a review of the Go Mic Mobile wireless kit soon.

What I did see at IBC was a wireless kit for smartphones from Chinese brand Comica. It’s a UHF system with a 40 meter range and a 3.5 mm output. It’s still a prototype, it should be available in a couple of months.


I’d like to travel light, so I prefer a LED light that’s light, but powerful. I’ve seen two interesting ones, both from Chinese brands. I’ve been testing a sample of the Menik STL-9 (left picture, just one unit) for a couple of days now and so far I’m very satisfied. It’s light, has a white diffuser, a yellow filter, a good internal battery (charging via USB), solid buttons and the intensity is adjustable with a small wheel. Price: around 20 euros. It’s not available anywhere online yet.

The Commlite Comiray L50 (right picture) looks almost the same. This one is available at various web shops for about 30 euros. On the same picture: a modular grip system by ViewFlex (not available yet).

Death warrant

Apart from all these innovations, what surprised me the most at this edition of IBC was the total lack of attention for the whole mojo movement. Of course, IBC is focused at these multi-million dollar companies, it’s not organized for indie filmmakers or individual journalists. But still, it’s so strange that a lot of these big companies try to ignore that there is a huge shift going on in content creation. In Glen Mulcahy’s speech, he talked about broadcasters signing their death warrant if they ignore the possibilities of mobile. That’s also true for most of these big companies that exhibit at IBC. I’m curious what’s the difference gonna be when I return to IBC next year.
