Review on 🎙️ Lewinner Wireless Lavalier Microphone Bluetooth Lapel Clip-on Mic for iPhone Android iPad - Ideal for Video Recording, Vlogging, Content Creation, Interviews - Noise Reduction, Auto Transcription, Auto Sync - Superior 48KHz Quality by Steven Adams

How: Surprisingly good sound. I made a video to test the audio, which I've included with this review. Rechargeable via USB cable. Comes with a handy carry bag. The application that the microphones work with has a picture-in-picture recording function. It is actually a good recording app. The application exports the recorded video file to the phone and many other video applications that I have downloaded. You can use it as a Bluetooth headset for phone calls. Headphones are connected to the device itself. You can use your own wired headphones with it. He's really small. Compare it to other wireless microphone systems that require two devices (transmitter/receiver) to operate. Cons: Doesn't work with other apps* (works for phone calls). I hope they open it. It records outgoing audio like almost any other Bluetooth headset.* According to their website, if you have TWO devices, you can use their mics with other apps. I only had one module so I couldn't test it.
