Review: I will not buy this again - Receiver battery easily drained. Most of the time, unnecessary noise creating a not clear recording. Packaging is not that neat. I wish to return this product.
Review: Ottimo prodotto - La qualità del suono è ottima. Nessun ritardo. Lo si può usare con tutti i microfoni. La batteria dura poco , è consigliabile portarsi un set di batterie durante una serata, ma solo per il trasmettitore. In quanto il ricevitore lo si può collegare ad un alimentatore qualsiasi con cavo usb. Tutto sommato è una ottima alternativa ai cavi audio che spesso limitano il raggio d'azione.

### ⭐⭐⭐⭐⭐ What a great little bit of kit
*by T***E on 13 May 2026*

Ok I was not holding my breath with these I have had a few less than satisfying experiences with wireless connectivity on my PA system in the past. But I needed a solution for a speaker that was in awkward place last night and running a cable was not an option sadly so i read a couple of reviews and took a chance and of course knowing if they were no good I could back them . I used a 3000mah lithium ion rechargeable AA battery switched it on at 7pm and it worked perfectly, I did leave it running after the hour or so I needed it just to see the run time , so the receiver stopped working at around 11pm and the transmitter stopped went to a red light at 12am so all in all I’m very pleased with them so much so I’ve ordered another pair. The sound quality seemed absolutely fine with no drop outs this was with music and speech. I do have some small 8000mah power banks that I will be testing with them at the weekend, I’m hoping they will run for the duration of the event . Ok so if I had to criticise any thing it would be the plastic case which I’m sure will be fine as long as they are looked after , I have Chauvet DMX dongles which I would give the same critique to and they were silly expensive. So in short connect is simple sound quality is great and the runtime is fine .
