To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I ordered this speaker from Jabra and faced two major issues - connectivity (fundamental issue) and battery life (important issue). The speaker came with a battery that would barely last for three hours even without a single call and the bluetooth connection would often drop. The only reason I purchased this over other alternatives is that (I hoped) Jabra would provide customer service. I logged multiple calls with them but no response whatsoever. It's a black hole. I would stay away from all-things-Jabra in future. Most of their products work just fine but when they don't, you are stuck with a very expensive and defective product.
There are other reviews that mention this. When its plugged in to USB the microphone sounds distorted to other users. It means I can only use the unit unplugged - which causes problems when you run out of charge.
Obwohl in einer sehr ruhigen Umgebung gearbeitet wird, beschweren sich die Gesprächsteilnehmer über Qualität und störende Hintergrundgeräusche. Einrichtung, Nutzung via Skype und Teams hat gut funktioniert. Die Sprachqualität macht das Gerät leider unbrauchbar und ich habe es zurückgeschickt.
