Review: abbastanza piccolo e carino, suono dettagliato, un buon suono tra l'altro regolabile con Eq e qui iniziano i dubbi, tante regolazioni e tante possibilità ma in cinese o in inglese, come il manuale, non c'è traccia di italiano. con le mie oberon 3 è fantastico arrivo a 30/40 di volume massimo e già si sente forte senza scaldare eccessivamente. il display è chiaro ma non a colori come mi pareva di aver letto, comunque a mio giudizio personale prestazioni sonore superiori a wiim amp. tanti dubbi su menù regolazioni e eventual8 aggiornamenti visto che manca la connessione di rete. per ora lo provo avrei preferito cose più semplici come controllo toni tramite banali manopole ma così va la moda oggi.
Review: Si estás pensando que puede sonar mucho mejor que un altavoz bluetooth, estás en lo cierto. Cómprate unos buenos altavoces pasivos y a disfrutar.
