Used it at big events with crowds of 7k ppl and it worked smoothly, I have brought a couple of xlr to 3.5 female converts to connect it to big mixers works fine

The product is very good regarding the charging case and compact form and battery. But the sound is very bad and noisy. It is little noticable during YouTube or Spotify playback. But during recording, there is a clear buzzy sound which is there. Each stroke of guitar or similar instrument creates more buzzy fuzzy sound which is verymuch annoying. I need the form factor and there is no similar product available at this price, that why I won’t return this item. The company should work on the buzzy sound.

Fantastic entry-level wireless for IEMs
Not sure why others are complaining about noise/distortion with this unit – I plugged it in out of the box in my home studio and it sounds great. I use it for silent practice at home and for my online lesson sessions. Both transmitter and receiver are small and well-built. The receiver has a convenient belt-clip and the transmitter has an included 1/4 in adapter for devices that have a 1/4 in headphone jack (e.g. most audio interfaces and mixers). Battery capacity seems great – I had it on for 4 hours out of the box without charging and it didn’t run out of juice. The volume controls on the receiver are solid and very responsive – this thing can provide all the volume you need.I highly recommend this as a great value wireless system for IEMs for at-home and small venue use for gigging.

Works great – better quality than my Shure
I read all the bad reviews and bought them thinking I would possibly be sending them back but what a surprise – they are outstandingly good. The only problem I can foresee is the fairly short charge – I will have to remember to turn them off between sets or I may even buy another so I can use and charge all night long.(I do a total of 1 3/4 hours on stage playing but I am there for up to 4 hours) but well worth it for the excellent sound quality.

Rauscht leider
Tolles Konzept. Bei mir im Setup allerdings zu viel Nebengeräusche.

Only lasted a year of very moderate use…
performance-wise excellent unfortunately after one year and a day the transmitter ceased to function and I have yet to have heard form either Amazon or the manufacturer about a refund.
