Sounds awesome and super easy to use with my iphone X, just needed the lighting to 3.5mm adapter though that came with my phone. The mic is pretty sensitive so don't have it too close to your chin, I attach it maybe 15-20cm below my chin just below my collarbone and that seems to be a good level
Been using this for my vlogs on YouTube. Comes will everything you see on the box. Great sound quality, just have to remember to look at the switch to ensure I've turned it on to the smartphone button! Used for 3 weeks now, batt is still going strong.
