Hybrid Meeting MUST HAVE!
We started doing Board training for our clients a few months back. We keep finding new stuff to make it better because we do it in a virtual meeting format so people can attend in person or via Microsoft Teams. The first meeting we used our Owl Labs 360 degree camera and microphone setup, which we use a lot in Board meetings. It worked, but not great. Next we used my wife's mirrorless DSLR camera for the video, which worked great for showing the presenter, but we still used the Owl Labs to show the audience and as a microphone to pick up the audience's audio when they asked questions. The video from the DSLR was great, but the audio sucked. Next we used the DSLR with a single lav mic that was rented from a photo equipment supplier. That worked awesome for the presenter but they had to repeat whatever in-person attendees asked so the virtual attendees could hear. Finally we got these mic's. Connected to the DSLR, with one mic used by the presenter, one by the person watching Teams for questions, and two that could be passed around for in-person attendees to use when asking their questions. BOOM! This was perfect! Now the virtual attendees could hear everything that the in-person people could! These work great! I really don't know of a negative aspect. So cheap compared to most other options. Fairly small devices. Charge quickly and the charge lasts longer than I need.

Doesnโt deserve 1 star
Iโve had a terrible experience with these microphones. It only worked well on film day one time but after that, the receiver never connected to the microphones. It just kept blinking over and over and wouldnโt connect to my camera. Donโt bother buying.

Update: Works with Android! But need Boya 3.5mm to TRS cord
Really great product! You get 4 awesome mics! It works with your camera or with a smartphone. However, if you plan to use it with your phone, you need their 3.5mm to TRS male cable which is sold separately for like $18. The customer service was awesome and they sent me the cable for free! There is no other product like this on the market. This simplifies so much! No more pounds of cables and old technology. If you use Android, you'll need to use the Open Camera app and in the settings, audio, choose "external microphone". And that's it! :)

Great
Use these mics for interviews. They pick up sound really well. Go a bit tinny and robot if youโre holding it a few inches away from our mouth and sound a bit muffled when you pin it to your collar. Best results seem to be without the muffler while pinned to the collar or with the muffler being held 6+ inches away from the face.

Great product.
My wife uses them for her office videos and radio spots. Great sensitivity, range, and sound . No issues. They just work! It would be great if they would make an all-in-one charging dock for this product but Iโm still very pleased with this purchase!

Mics are awful and unreliable
I have been using these for podcasting and my cheap mics that plug right into my iPhone were much more reliable. These are very unreliable whether plugged into my phone or laptop. Weโve lost about 10 hours of podcasting due to the mics not picking up anything.

Good buttttt some issues
Mics seem to work alright, issue is it picked up more of the sound of us unwrapping stuff than it did our voices....
