UPDATE:Have this item for 7 months already and its just great! Batteries last for months, i take the mic with me everywhere i go because of my work, started to use the channels recently to avoid any interference. Just wrote this update to let all of you know that the mic works great after months of use. Use this 3-4 times a week.Helo everyone. I bought a lot of photography gear and I have 2 clients, 2 girls who have an online channel, they do make up and I film their show, I have 8 lights, tripods, camera and so on. The thing is that the audio was really bad because i was recording just with my camera and I needed a good microphone. Took a while to find what I need and I bought this item for several reasons. Well, read a good review from someone who is audio specialist, another reason is that I already have 4 K&F products and they are very good, I trust this company. I made a video review, the audio quality is not so good because the files are comperessed but the original is good, i am not an expert in audio but personally i am really satisfied with the results. I filmed since I got the item around 4 hours and it totally makes the difference. Why I bought this lavalier microphone instead of a regular one? Well, I am planning to film some interviews for some hotels and I really need this type of product. As i am working withe these girls, i have placed the actual mic under the blouse just to hide it and the quality is good. I didnt try super high end products in this niche but for what I need its very good. I have tried it like 20-30 m away and its ok, this is the maximum distance i will need it for, for my interviews. Light and easy to use, I know that i need to have with me spare batteries which I am carrying all the time, read that they last for a long time. You got in the pack a spare small microphone with jack at the end. The cable for the micrphone is long enough, clip is made from metal not plastic which on a long term pretty sure it will last. I will pay attention to the antena of the actual mic because if its going to be under the clothes(attached to the belt because this is where actually goes). I have tried different volume intensity, in my case found that 7 is good enough. My suggestion is to place the microphone around the chest area, next to the neck the volume was a bit too high(red indicators on my camera). Pretty sure you can set it up as you prefer. For what I need to film, it took me 15 mins of tests to get the sound i was looking for so happy with this.You know, when you trust a brand you go for it. In my case its like this. K&F very good! The box is small and light, has this protective sponge(think its called like this) and I use it to carry them from location to location. I just put the box in the small pocket of my backpack and its all good.
