Doppelset Preis ok
Empfang fällt leider öfters aus - Bluetooth Empfang

Entweder schlechte Qualität oder Montagsgerät
Verarbeitung und Handhabung sind sehr gut, ebenso die Akkulaufzeit. Die Rauschunterdrückung während der Fahrt und die Audioqualität mit den HD Kopfhörern ist wirklich gut. Das Verbinden mit der App war manchmal etwas schwierig. Bei mir und meinem Gesprächspartner war jedoch ein ständiges Knacken und Rauschen zu hören, auch nach einem Reset. Der Sena Support konnte nicht weiterhelfen, also ging das Gerät nach ein paar Monaten zurück. Die Erstattung durch Polo erfolgte ohne Probleme.

Zu teuer für die Reichweite
Wie der Vorgänger schon beschrieben hat, ist die Reichweite wirklich nicht toll und die Qualität der Übertragung mit Knackgeräusche echt schlecht. besitze das Produkt nun ein Jahr. Von mir leider keine Kaufempfehlung!

Preiswert, Funktion ausreichend
Leicht zu installieren, verbindung zum Handy und Bedienung top. Aber, die Verbindung zwischen den beiden Geräten ist leider katastrophal, beide Geräte auf aktuellste Firmware, Akku voll und dennoch dauerhaft Störgeräusche, wenn bei sportlicher Fahrweise der andere mal 500m weiter vorne durch die Kurve fährt, führt das teilweise schon zu Verbindungsprpblemen und starke Störgeräusche. Regelmäßig denkt man aufgrund er Geräusche, dass der Kollege gestürzt ist aufgrund der Störgeräusche...
