Let me being with the Amazon review mantra: "I usually don't write reviews for products but..."OK, now that I got that out of the way ? , Let's talk about this Lav mic!I felt compelled to write about it because I expected another L from Amazon. I bought the Pop voice mic, and maybe mine was a dude but it didn't work. Wouldn't work on my mac or my phone. A complete waste of money. I decided to give this one a shot before I bit the bullet and purchased a guaranteed good (but pricey) mic like the Rode Plus.I was confident due to the reviews but I've been fooled by cap on this app many times. People hyped for a product that ends up being trash. For the price, it was worth another attempt to add a quality lav mic to my home studio setup.The packaging and product is as advertised in the pics you see. I didn't have trouble installing the battery into the power section. The packaging is clear and separates all the parts so you're ready to use it out of the box.I tested this on my Macbook Pro using the USB attachment (I needed an adapter because this isn't USB-C), On My MB Pro using my Focusrite Scarlett 4i4 third gen (there's a 1/4 adapter included too) and on my iPhone. I can report that the sound is clear and the lav just works! It's sensitive and picks up background noise, as I could hear my heater on faintly, but it's not bad enough to detract from your audio. Worst case you can eliminate those minor sounds in post-production.The attachments allow me the versatility to use it on any camera and laptop. I didn't test in my Canon camera, but if it works on a Macbook (which also requires the Camera button to be ON to use it), then Im sure it can work for a DSLR. I tested this in Quicktime on the Mac, on the Camera and Voice Notes app on iPhone with no issue. Ditto for the Focusrite. It's great to have gain control on the audio interface so I can adjust it.The mini Camera/Smartphone power pack has a little weight, but it also has a belt buckle attachment, so think of it like a wireless lav mic receiver. it's easy to hide and shouldn't be too cumbersome.If this had a gain control option, it would probably cost more money, but it would also be even more perfect. For a lowe price, you get high-end quality sound that's serviceable enough for your Zoom calls, iPhone recordings and anything else you need to do that requires dope audio. Highly recommended.P.S. - it doesn't work if you want to send a voice note in the messages app and I didn't test for FaceTime, but those shouldn't be your primary or even secondary use case for a lav mic. If y'all want an audio test let me know and if enough request, I'll add it.
