Bietrun Wireless Microphone Headset, UHF Wireless Headset Mic System, 160ft Range,1/8'' and 1/4'' Plug, for Speakers, Voice Amplifier, PA System(Not Supported AUX/iOS)

I bought this based on the price and reviews. I plugged it into the portable sound system in my classroom, using the 1/4" adapter that comes with it. It works quite well, especially for such a cheap price. The only issue I've had is after several hours of using it (by seventh period) it starts making an electronic-like "popping" sound. I wonder if that's because the battery is low? If I remember to turn off both parts during my planning and duty periods, then it doesn't happen. Once it's charged up again, there's no more popping. For the price, I definitely recommend this wireless microphone headset system.

I am a full time teacher and I DJ on the side. I have a PA in my classroom that I plugged two of these into through a mixer. I share my classroom with another teacher so I bought 2 of the headset units. I own Shure and AKG wireless mics for DJing and have found you get what you pay for generally so I was skeptical about a mic that was priced so low, but figured I didn't have much to lose. We have used these for for about 100 school days so far and they produce clear audio that rarely drops out. The furthest I get regularly in my class is maybe 40' from the receiver and I only remember one time it cut out for a split second. I don't know if I'd use them for paid gigs where sound needs to be perfect, like a wedding or important speeches, but I might, and for my application, I am completely blown away that you get a headset mic, transmitter and receiver that functions fantastically. We use them both for about 5-6 hours a day, and the battery seems to hold up well, we charge the headsets every night and usually charge the receivers as they are plugged into my mixer while using them. The only thing I struggled with was using two simultaneously, but as long as you follow the directions pairing them on different channels works well. When using two headsets, the channels can get mixed up when you turn the headsets off and on, but I found all you have to do it turn both the mic and receiver off, first turn on the headset, second switch on the receiver, and they sync up every time. Very impressed for the price! Don't the inexpensive cost discourage you, this is a great value!

I am a fitness instructor and have purchased several of these mics over the last few years. They are great! The price is reasonable (I use these for my pool classes so I don't want an expensive microphone) My only complaint is if you lose the connecting jack you're out of luck. I cannot find replacements anywhere. I've ordered what looks like the right thing, but they never work. Whatever you do, don't lose it!!!

Extremely lightweight. Very low cost compared to others. Volume control easy to use but I didn't notice much difference in the first 3 clicks, however the 4th click increased the volume significantly. Overall volume and sound are great. Battery lasted almost as long as suggested and probably would but I didn't want to wait until it ran out and be cut off mid performance. Compared to another I have used, there is no squelch control, only simple volvume up or down so I was concerned that I may not be able to adjust to avoid feedback near speakers, however it was no problem with this mic. I could walk in front of speakers with no effect, until I got about 12 inches from the speaker, then got feedback but WOW! Can't believe how good these mics are and the price is great. I also tried it in several different dance halls and in one large hall where the receiver was up on a high stage and not in direct view, I thought the transmission may be difficult but there was no drop out and it worked a treat. Similarly when I walked out of the room and the doors closed behind me, although I was not very far from the receiver, I was out of view and behind closed doors and it still worked perfectly. I know they will eventually require replacement when the battery will no longer charge, so it's a shame to know that the whole thing will become useless and non maintainable as I detest the throw away society we live in but with 2 or 3 charges per week I reckon mine will last 3 years or more. Being lightweight to wear and carry to gigs, easy to set up (simply plug in and go), quality sound and long battery life, I no longer use my £300 wireless mic, instead I use this cheap but brilliant little alternative. Can't speak highly enough of it. Beware of other models that I tried before I found this one, which look the same and are about the same price but the sound is not comparable and they are not as easy to use. I sent them back and got this one after a friend recommended it. I had to order it from the amazon.com (USA) and have it delivered to the UK but it was completely worth it!! I have since ordered one for my partner and will replace them when the batteries die. I hope they are still available then!!

I find it’s working very well.

Problem with ground when plugged to a full PA but ok on small portable bluetooth amp.

Dudaba de la calidad de audio, pero me sorprendio, se escucha nitida, no mete ruido y tiene alcance bueno para el área que la necesito

Good sound quality Charging up to 4 ours continueosly Easy to use Nice looking Comfortable Easy to handle Sound adjust at hand Voice clarity is very good Must buy if there is no problem with budget
