Review: Sounds like high end with a low end price tag - This wireless microphone set is easy to use, seems well-built, and does exactly what it is supposed to do. The microphones have what's called super-cardioid pickup pattern, meaning they have a very small pickup pattern, mostly in front of the diaphragm. When your mouth is 1-3 inches away the sound is as good as any consumer-level microphone I've ever heard; and they won't pick up a lot of unwanted ambient sound. The construction of the microphones seems very solid. The body is metal, not plastic, and they're actually kind of heavy. Not to the point of not being able to hold them for long, but heavy as in: it feels like if you drop one, it won't break because it's metal. One drawback to this construction is that these microphones are very thick... So thick that none of my standard microphone holders for use with stands will fit these - and they don't come with microphone holders, either. My application is such that I need these to be able to be attached to desk or boom stands. As this set comes, they can only be used hand-held. If the microphones weren't so thick, that wouldn't be a problem, because I could conceivably use microphone holders I already own with the stands I also already own. For that reason, I really think the set should come with microphone clips/clamps that work with these OR the microphones should be designed to work with standard sized microphone holders. Now on to the receiver. It's rack-mountable, which is a huge bonus if you're planning to use this system in a rack. Some other offerings are simply boxes with no mount. This receiver is simple: One place to plug in the power One power switch Two places to screw on the antennas 4 XLR outputs (one for each microphone channel) One 1/4" output that mixes all four of the microphones down to a mono output. 4 level control knobs So, the receiver is a mixer if you use it with the 1/4" output, OR it's simply a receiver if you're taking each microphone and feeding the audio from it into an external mixer from the receiver. It's just that simple. It comes with instructions, but they're hardly needed at all. The level control knobs located on the front of the receiver act as level/volume output controls for each individual microphone. I hooked this system up to a sling studio live streaming video device and found that the mono sound comes only from out of the left channel. So I'll have to use an additional mixer if I want to use these microphones for my live video streams. That, and, like I said before, I will also need microphone holders that can accept microphones this thick. So what does all this mean? If you need a wireless system and you don't need to use the microphones on stands AND if you have an additional mixer that can turn a left channel only signal into mono (both channels), this system is a great buy. It comes with everything you need (even batteries for the microphones) to be up and running with it in five minutes or less. So, in summary, the pros far outweigh the cons. I found only two things to complain about. This system is a great value and does exactly what's advertised.
Review: Great, simple to use, good value for investment! - Great for a small church choir, this is the second set, first went to my home church, second set went to a church a friend is on the board, simple to operate, good sound!

## Questions & Answers

**Q: Can I connect this to my sound bar?**
A: Hi,could you take a photo of the back panel of the soundbar?
Please contact us at support@innopow.com.cn
Normally if you use smart tv with only digital output.
then you will need a digital to analog converter, 
a mixer mix the TV music and mic voice,
then use cable connect to sound bar,
but if the sound bar only has digital input, then you will need an analog to digital converter and a couple of cables.

A: Hi, please contact us at support@innopow.com.cn, if it is defective mic, we can provide the replacement.

### ⭐⭐⭐⭐ Very good product for the price.
*by J***L on September 2, 2025*

Bought it for Very good quality for the price, doesn’t consume battery really fast. It’s lightweight but not to the point that you would think the quality is poor. Has good range and the sound quality is still good even at a distance.
