They are Not Shure or Sennheiser but they work
We bought these as a reserve set as we did not have enough “proper” kit.We were nervous about using these and so set the receiver up well away from the main desk by the main stage and ran a separate analogue snake back to the mixer.The sound quality was not fantastic compared with our existing Shure and Sennheiser equipment. And, of course there is NO flexibility on transmission frequency.However, we used them for a week long conference in a separate room where speakers were often wandering a hundred foot off the stage and these performed well after figuring out an acceptable compromise on the EQ.We only used the headsets and these are ultra lightweight. The cable is a little noisy and the battery pack is plastic, but lightweight.After an initial test we labelled up the receiver, transmitters and XLRs into the desk and ran all four together and everything was OK.We would probably only use them for speech, compering, MC and that kind of thing and we would make sure we had no other UHF stuff close by.However at less than £150 these are AMAZING value. When you think that the standard Shure equivalent (ish) would cost 10 times that, albeit with better sound quality and much better transmission and receiving flexibility this has to be god value.Then adding that they work OK for presentations and speech with fantastic battery life and with both lavaliere and headset options for the transmitters, this has to be recommended in the right circumstances.We have flight boxed ours and it travels with us all the time (even when nothing is booked) just in case we need to support an event with this kind of mike. For large scale events then it is limited but if you do not need more than 4 mikes then it is recommended.We have since used these in a 150m by 20m room alongside two cheaper Shure BLX SM58 hand helds and two GLDX digital SM58s. All worked fine – although the GLDX did need lose some range for some reason which was probably unrelated.Lastly, a comment on the the quality of build, since this has been marked as a negative by some. We found the quality of the receiver to be perfectly fine and as robust as any Shure receiver. The PSU is a standard one and we just added a spare with the right connector into the flight case.The transmitters are plastic but feel solid and well made. The clips work. The battery compartments are secure. The control is easy to get at – although a slight niggle is that presenters can adjust them on the fly which can screw with the mixer setup. The headsets are not great quality and I suspect that these are the fundamental reason for the poorer sound quality coming through the system. However, they are more than adequate for conferencing, MCing, …These are made to a very low price point and made well for that price point. A couple of small things which would make the system even better for very little extra would be a case where everything had its own place – we use proper flight cases but I imagine that most customers would not do this. Secondly to colour code the receiver XLRs/gain controls with the transmitters. That would save setup time for the first use.If you have read all the way through our review then thanks and well done.The short review is that this set is absolutely recommended and well worth the money.MusicZon

Excellent product
This item worked perfectly âout of the boxâ. Easy to set up and use, and did exactly what I wanted it to do. The headset microphones work well, but take a little practice in positioning. The addition of the clip on microphones was also useful, enabling me to include my bodhran in the mix. Sound quality was better when used with a mixer / p/a rather than directly into an amp. All in all, a good product at a very reasonable price.

Not cheap but well worth the money.
Bought this kit in part because of the choice of using lapel mic or hand held whatever suited on the night.I was extremely happy and surprised when I received and opened the package. It has a robust metal housing for longer life. The receiver is going to work hard and needs to be sturdy. The mikes are inter changeable so you could have the person in charge using a Hand Held Mike whilst supporting cast used lapel one. There are balanced XLR inputs in the case for local wireud mikes, so as to be versatile

These are easy to set up and use. Not high-quality but amazing for their price range.
Bought this set of headset microphones for a school musical for 11/12yos. Needed them in a hurry after other (more expensive) mics broke down. They arrived quickly, were easy to set up, and were perfect for the show! Although a cheaper product than available elsewhere, they still had decent sound quality (plenty of volume, clear enough for solo performers), fitted small heads and were sturdy enough not to be broken across three shows of dancing/costume changes. Signal was consistent across the length of a gym hall so sound carried perfectly.Though more expensive mics might be better for more professional settings – better battery life, less visible headsets, mute button on belt pack – I would definitely recommend these for less formal settings to get a lot of use for a great price.

Works well, sounds good, good value
We needed multiple radio microphones for putting on a play in a difficult acoustic (an old courtroom – wonderful, but echoey) and these work very well, at a really good price. I did look at hiring some, but that would have been considerably more expensive!

Decent Packs, bad microphones
I use this at full capacity in a small 5m x 6m room for tabletop battle reports. We have players and someone who runs the stream so everyone is hooked up with a mic pack from this system. Setup is great and the packs themselves are great and last beyond the 4hours we need them to using some Lithium rechargable AAs that are 1.5v from Amazon. The one downside is the included lavelier mics are of extremely poor quality. Fortunately I had some spare laveliers from my Comica BoomX set and after plugging those in the audio quality vastly improved. The headset mics included are bizarrely loud compared to the lavelier’s but seem to be better quality. The system is fine, though I wish I could afford digital instead of UHF, but you will need to buy alternative laveliers.
