Review: Il prodotto sembra ben fatto ma l'ho reso in quanto non era ciò che mi occorreva
Review: Funciona perfectamente, yo lo utilicé junto al collar bluetooth que no lo incluye pero lo puedes comprar aparte , haces una grabación en el móvil mediante una app llamada grabadora de voz , pones la pila en el pinganillo, conectas bluetooth del teléfono y conectas el collar , este tiene un botón donde puedes pausar la escucha y si vuelves a pulsar el botón vuelve a oírse , nadie se entera si pones el sonido de la grabación bajito y el pinganillo si lo introduces bien en el oído apenas se ve , en mi caso con el pelo es imposible verlo. Lo recomiendo. Única pega es que la batería del collar es de 3 horas y tienes que volver a cargarlo , y la pila del pinganillo no lo sé lo que dura yo para no arriesgar recomiendo poner pila nueva si vas a estar un par de horas de exámenes.

*by S***G on 25 June 2025*

Ich war im Vorfeld sehr skeptisch ob das Produkt hält was es verspricht, aber ich bin durchweg überzeugt. Positiv ist hervorzuheben, dass es wirklich absolut unsichtbar ist. Der Stecker verschwindet komplett im Ohr und lässt sich auch nach der Benutzung problemlos wieder heraus ziehen. Der Klang ist nicht 100%, aber vollkommen ausreichend das man alles versteht. Es sei den es wird laut um einen herum, was in einer Klausur aber selten passiert. Aussehende Personen hören nichts von dem was über den Kopfhörer abgespielt wird. Akkuleistung ist wie beschrieben, bei mir hat sie eine drei Stunden Uni-Klausur problemlos durchgehalten und es war noch immer Energie da. Fazit: Klare Kaufempfehlung wenn mal nicht genug Zeit zum lernen da ist 😉
