Review: Funziona benissimo, grazie - Funziona 😍 L'audio si sente un pochino ovattato ma si capiscono benissimo le parole, fantastico! La prima volta che l'ho provato ho sbagliato a metterlo, avevo inserito il magnete quello grande anziché quello piccolino, quindi non si sentiva bene. Dopo qualche tentativo ho capito che stavo sbagliando tutto quindi ho inserito il magnete piccolino (ve ne arrivano due nel kit, uno è di scorta quindi dovete separarli ed inserirne solo uno), probabilmente dovrete fare più di un tentativo prima che si posizioni nel verso giusto, ma vi assicuro che funziona. È anche semplice da collegare con il Bluetooth.
Review: Beautiful useless item! IMPOSSIBLE to understand a thing! - I bought V4 for an important event and I couldn’t help to make it work!!! After carefully following all the instructions I understood with the customer service that I was everything ok… Nevertheless even in an extremely silent house, I could barely listen to the drums of “ACDC” as a test having a finger inside in my ear. Listen to a call is absolutely impossible. I would like to underline that: - battery was charged all night; - neckloop correctly and easily paired (at least); - neckloop volume at max; - phone volume max and sound mode; - item correctly inserted in both ears; —-> but still a far and impossible to understand voice!!! It has NO USE! They even asked if I had my ears properly cleaned!!! Result: event mismanaged! Item returned! My advice: DO NOT SOLELY RELY ON THIS PURCHASE AND TRY YOURSELF TAKING YOUR TIME FOR A PLAN B…

*by A***O on 12 January 2021*

El pinganillo funciona perfectamente. A mí me ha llevado 3 días para conseguir la introducción correcta del mismo pues a pesar de que seguía las instrucciones no lograba escuchar nada, finalmente pude introducirlo tras varios intentos y gracias a los consejos y ayuda a través de WhatsApp y mail por parte de la empresa.
