### ⭐⭐⭐⭐⭐ Amplificatore efficace
*by T***O on 31 August 2024*

Questo amplificatore l'ho usato con mia suocera molto dura d'orecchio dato che le mancano 40dB di sensibilità e gli apparecchi acustici non sono più sufficienti. C'era da sgolarsi e irritare la gola. Con questo prodotto abbiamo risolto brillantemente il problema. - Design lineare, con spigoli arrotondati, molto gradevole. - Ottima qualità costruttiva, solido e robusto. - Pratico ed ergonomico, dotato di cinghietto con comodi piccoli moschettoni per tracolla, clip per cintura/tasca. - Buona potenza e qualità sonora, difficilmente distorce. Rumore di fondo molto ridotto. - Microfono cablato comodo, si può regolare la posizione, meglio metterlo molto vicino alla bocca. - Regolazione del volume con interruttore on/off incorporato e led d'accensione. Con volumi molto alti e microfono molto vicino o orientato verso l'altoparlante si rischia il sibilo, ma questo è comune a tutti questi device. - Ingresso Aux per sorgente audio esterna con relativo cavo in dotazione. Con un buon equalizzatore esterno si riesce a tirare fuori una discreta qualità musicale, l'altoparlante risponde alle regolazioni, ovviamente i bassi non sono profondi ma gradevoli. - Ricarica tramite Usb-C con relativo cavetto in dotazione. Durante il funzionamento il led di accensione da verde diventa rosso quando necessita di ricaricare la batteria; viceversa durante la ricarica da rosso diventa verde a carica completata. La ricarica non è un fulmine.
