Bonjour ouf .!!! enfin il est arrivé merci je commencé a perdre espoir je vous remercie a tout le monde a toute l'équipe bang good qui on fait que j'arrive a entendre merci bang good .
its ok
I bought it for my grandfather and he loves it. It's good to adjust voice level as he said. He recomends it.
works fine, a bit big but ok for home use anything smaller would be many times the price !
Il dispositivo non è da intendersi come una protesi acustica, ma può essere di aiuto in situazioni in cui occorre aumentare il livello sonoro percepito, può essere adattato facilmente all'orecchio con i vari tipi di gommini presenti, buono il rapporto qualità prezzo
super
works fine for the price. its a small variable amplifier with an optional bandpass filter that can be toggled using the switch.
I received the equipment and the quality seems very good Thanks and Regards
