Review on Bietrun Microphone System: Ultimate UHF 165ft Range for iPhone, DSLR, PA Speaker, YouTube Recording by Jennifer Ross

I love this mic. It comes with lots of extras so you can make it work for you. Three different plug adapters for different connections. I couldn't get the microphone to work on my new Lenovo laptop. Luckily I have a USB sound card adapter. I connected the receiver to the adapter and then it worked fine. I wanted a wireless lavalier mic because I demonstrate martial arts on Zoom, I'm 10-15 feet from my webcam and I'm moving. Other instructors quickly lose audio quality when moving around, and sometimes with their backs to the webcam. As for the microphone itself. The sound quality is slightly better than the webcam. I think the output volume is a bit lower but has more timbre than the webcam. I think the problem was pinning the mic on my collar. When I clipped the mic to my shirt, the sound got louder. The reasons for 4 stars instead of 5 stars are as follows: 1. An additional device is required to connect to my laptop as described above; 2. Battery life is a far cry from six hours, at least for the transmitter. To get a good sound in Zoom, I turn the volume up to maximum. I guess, so I think two hours is all I can get out of it. I actually used it for an hour and it was already on the same powerband. I have a different wireless mic and had the same issue connecting to a Lenovo laptop, so the issue might be with the Lenovo. Another nice thing about this article. The two halves must be charged via USB. It doesn't come with a charger. However, it comes with a dual charging cable, so both the transmitter and receiver can be plugged into one charger and charged at the same time. One day I lost the connection between the receiver. I read the instructions and was able to reconnect. By the way, you can be sure that the instructions were not written by a native English speaker.
