In this review, I will be specifically looking at the Synco P2L wireless microphone for iPhone, which includes two transmitters and a dual channel receiver that plugs into an iPhone’s Lightning port (and there is a P2T model with a USB-C receiver connection for Android devices too).

In the box, you get a paper manual with information on how to care for, set up and pair the P2L microphone. There is a USB-C to 3.5mm adapter for audio monitoring from the receiver to a connected pair of headphones, there is a 50cm long USB-C to USB-A charging cable, and finally, there is the P2L recharging case with the Lightning receiver and two wireless transmitters charging inside it.

It comes in two colours, this Stone Blue colour and there is also a Pearl White colour option also. The case feels rigid and protective and it features a single USB-C port for charging the case’s 300mAh internal battery, and there is a physical pairing button, which can also be used to check the case’s remaining battery level, which is displayed via the 5 LED light strip on its outer casing.

Charging Case & Battery Life

The case houses a draw-like tray that you depress to unlock and slide out to reveal the two charging transmitters and Lightning receiver inside. Charging of the transmitters is shown on their LED light strip, which glows red in colour, and this light strip is also used to show when they pair and also to monitor their battery level.

Along with the charging case, each transmitter can last up to 15 hours of recording or 5  hours of recording from a single charge. A 10-minute charge from the case will allow up to 45 minutes of recording, and a full charge of 1.5 hours will allow up to 5 hours of recording. So in short, you’ll get a total of three full charges from its charging case.


Pairing both transmitters to the receiver is simple. You first plug the receiver into the Lightning port of your iPhone, and once you’ve pulled out one of the transmitters from the charging case, they will power on and begin to pair with the receiver. Both will pair in a matter of seconds and their LED light strips will simultaneously light up and animate whilst paired, or they will flash if they have lost their connection and need to be paired. 

I did find the flashing lights, on the transmitter at least, to be a little distracting on videos where you might see the microphone clipped onto a shirt. The indicators are nice to see that they are paired, but it would have been nice to be able to turn it off or have this light strip be more discrete, possibly located at the side or at the back of the microphone.

Out of the box I first had issues with the pairing process. Both transmitter and receiver just didn’t want to pair. But I soon noticed that the receiver didn’t quite sit well in the case’s charging slot, likely due to how lightweight the receiver is. Holding the receiver down whilst pressing the case’s pairing button managed to fix my initial syncing issue with the other two transmitters.

P2L Receiver

The receiver powers itself by the iPhone’s battery once plugged into the iPhone’s Lightning port. It sits nicely below the phone without any extra bulk or weight, so the phone can still sit flat on a flat table surface and I found I was just barely able to use it with my DJI Osmo gimbal too. 

There is a USB-C port on the receiver, which is used along with the bundled USB-C to 3.5mm adapter for audio monitoring and to also hear audio prompts from the Vocal Effect button. So you can hear exactly what each of the two transmitters is sending and avoid any audio connection or volume issues.

Vocal Effects

Alongside the USB-C port on the receiver is a Vocal Effects, Mono and Stereo toggle button. There are 9 voice effects to select from that modify the spoken audio through both transmitters.

Each of the 8 additional vocal effects can only be applied whilst in Mono mode, and both Mono and Stereo are toggled with a long press of the vocal effect button. All effect modes are spoken to you with each button press, through the connected headphones of the audio monitor port. I found it unfortunate that all effect modes came with an echo reverb effect added to them, which felt like a bug to me, and because of this added echo, it made using most of them a little pointless, which is a shame, especially for the voice amplification option.

Wireless Range

The range between the receiver and transmitter can reach a clear line of sight of up to 150 metres or just under 500ft. Which is more than most people would need in my opinion. [PLAY BACK beach recording) 

At just under 50 meters of my test the microphones picked me up without any dropouts, and they also managed to cope with the sea wind noise quite well considering they don’t come with any form of spoffle or wind braking accessories.

I also tested the microphone connection between two internal concrete brick walls and one thick outer wall, and only at the third internal concrete wall did the connection between the transmitter and receiver begin to drop out. But seeing as most Bluetooth earphones also struggle at this test, I didn’t expect the P2L microphones to perform any better here.

P2L Microphone Transmitter

The microphone sits slightly low at the top of its casing, and it can also be quite sensitive to being touched, knocked or brushed against, so you’ll have to be careful about where you decide to clip the transmitter to avoid any accidental noises in your recorded audio.

In some instances, I also could hear some interference noise in the recorded audio when there were moments of silence or quiet background audio. This noise seem to be quite random when it appeared, but it wasn’t enough to become an issue for me. 

Final Thoughts

Synco also creates a single transmitter and receiver combo called the P1L and P1T for a little cheaper if you feel you don’t have the need for two wireless transmitters. However, having two transmitters would give you twice the recording time as you’d have a spare one to use without the need for recharging the one you just used.

Other than the minor issues I mentioned earlier, I found the Synco P2L microphone to be a very decent and travel-friendly microphone setup for your iPhone. If you want consistent audio levels, whilst recording at a distance from your mobile phone, then the P2L is a great solution that I would easily recommend for two-person vlogging, podcasting or live streaming from your mobile, with a great level of audio quality and a form factor that is lightweight, discrete, simple to set up and it is perfectly pocketable whilst you’re on the go.
