These are very easy to use microphones. Useful for video conferencing/presentations, vloggers, etc. NOTE: This doesn't work with my Android phone (Galaxy J6) and the instructions warns about this: “*****Some Android phones have incompatibility issues due to the operating system. Please contact your dealer ***** for more information. They work really well with my Chromebook, which is what I need them for, but if you plan to use them outside on a tripod etc, you'll want them to work with your Android phone. I only have the means to test this with the Type-C receiver, but there is also a flash and a 3.5mm receiver, so for Apple devices and digital cameras. The receiver connects via Bluetooth and requires no software, it's plug and play. The transmission works over the distance and is uninterrupted once I've played the video. I am very happy with the sound quality, build quality and accessories. They are compact, about 2.5 cm tall, light and are securely fastened with a strong clip. Two mics in this pack seem reasonable for the £65 price point. The only negative I can find is that it doesn't work with "all" Android phones. I really don't know how you would know if it would work with your phone without trying it
