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 😉
