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: 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.
