Review: Work great so far - Great so far,only used for our pastor twice,it was easy to set up, delivery was on par, price was great,not a complaint but I would prefer it to have a mute switch,but not a big deal,I can't speak of longevity yet, however it was easy to adjust volume so static did come from the speaker's,I used the lil bit of reading materials trouble shooting guide to whoop that problem,the sound is really good,we used the head mike because it picks up easier than the lapel mike, hope this helps
Review: Shockingly good - There's no disputing these are very basic and very cheaply made. But cut to the chase... ...we all want a mic to work with sufficient gain to be low-noise, that is to say 'usable'. These do. I bought them in a pinch, not having the requisite dollars to replace the failed "Better Brand", but honestly, these will stay in the rack for as long as they live. I'll never produce an $800/seat rock show, but for weddings and the like in various places, these really are more than sufficient. Battery life is as good as the 'Better" when running 3500mWh rechargeables.

## Features

- Debra Audio AU400 4 channel wireless microphone system.(Two set freuqncy point: A- 501/511.5/524/538.5 B-506/517.5/531/546.5)

- Squelch circuit usually analysis the intensity of the RF frequency channel instead of the noise and the needed signal. Using the low traditional wireless microphone in the complex environment or when the signal of the microphone is week or the microphone is closured, the squelch circuit many suddenly opened which result the receiver send out a strong burst of noise.
- It ideal for church, small DJ KJ stage, birthday wedding or family party, conference, classrooms, small karaoke night etc.

### ⭐⭐⭐⭐⭐ Great for in-home karaoke parties
*by J***W on November 27, 2025*

We use this for karaoke in our house, connecting this and our laptop (for music and lyrics) to a big Ion speaker and it works great. Sound quality is good for what we use it for. I love that we can manually adjust individual microphones as well (you know, there’s always one or two people in a group who sing waaay too loudly and need to be turned down a notch!)
