To calculate the overall star rating and percentage breakdown by star, we do not 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 purchased two of these in early April, 2019. I expected one to be a spare in a travel kit. By the end of April, the first had stopped working. After a week of degrading sound quality and seemingly spotty connections, the sound stopped completely. I can only guess that the connections inside the adapters are poorly made or soldered.
