Surprisingly decent wireless audio at a very good price! I've exclusively used Sennheiser EW series and Sony UWP series wireless lav microphones over the last 15+ years and these extremely inexpensive K&F UHF systems have given me a very decent backup option for about 1/5 the price of the other two brands.Is it as good as the much more expensive options? There is a little bit more baseline noise in the signal (nothing you can't clear up in post) and the range is definitely not as good as true professional options but there in nothing wrong with a little bit worse at way lower price.They work, the audio is pretty clear, they seem decently built and they are easy to use.

There is a lot to love with this set and a small amount to criticize, so let's take a look at a breakdown of what makes this set work it.Packaging:Everything comes extraordinarily packaged in a nice minimalistic black branded box. Inside everything is inset into foam inserts for protection. This is one of the few times where I can say that I will be keeping the package and using it as a method of storage.Build Quality:The main units themselves are made of a durable feeling plastic with metal clips on the reverse side. The door hinges are not the most rugged thing I have ever seen; however, you will rarely have the battery compartment open so this should not be a concern. All the accessories, microphone capsule and cabling all feel well build and should stand up well to regular use and travel.Functionality:These work very well. The range is surprisingly long, which should allow for versatile uses from personal video, to conferences and weddings. The controls are hidden within the battery door which means once they are set you should have no worry of them being accidentally modified. Upon testing I also received no noise or feedback while flexing the microphone cable. This can be used very easily with audio recorders, dslr input jacks, and computers with dedicated microphone jacks or with a TRRS adapter for single jack setups.My only small gripe with these units is at first glance it is very hard to distinguish which is the receiver and which is the sender. I will be color coding them on my own; however, would have liked to see some factory branding or a slight change in appearance. The included batteries are not the best either and you will want to grab a good set of rechargables to insure you get the most out of the equipment.I will be using this set for video production. Previously I was using a field recorder and syncing the audio in post; however, the preamp in my DSLR is decent enough that I can use these to capture "baked in" audio directly into my footage. If you are looking for a great microphone set that allows you the freedom to move around, I would certainly try these out!

They worked as described. Excellent sound quality for the money you pay. No complaints so far.

I was rather impressed with the audio quality. Very easy set up - I am using them with a Canon 6D.

 I was previously using the Boya BY-M1 lav mic prior to getting this one. It sounded pretty good and had about 20 feet of cable which was nice because you could go all the way across the room, still keeping your mic close for good sound quality. The main problem for me was navigating around the softboxes, lighting, tables, and chairs with the cable connected to me. This completely takes away that problem. It sounds great and keeps the mic close to your face. It also takes away all of that cable so you have the freedom to move as you want. It sounds great also and to me, better than the Boya BY-M1 for sure. I would highly recommend this microphone set. It easily connects and if you have a mic port on your camera/camcorder then this will work for you. It takes batteries (2 AA in each) so you are okay if you don't have "phantom power" on your device like some mics require. Please see the video for more details.

This microphone works great! Couldn't ask for anything more for the price. I set up my camera to film me across the street, and it picked up the audio no problem.

Just tested it on my Nikon D750 filming the kids for an hour. After playing around with various combinations of settings, I set the sensitivity on the camera to 11, dropped the volume down on the Concept and the sound was perfect.

Very powerful mic! Tried it with DSLR camera and it works!I wasn't sure how to use it with my PC and the customer service team helped me with step by step instructions. Thank you very much!

Very happy with it.

They are more than what they say and more! Perfect for what I'm using them for. Very good product and price,I would buy again.Thank You
