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.
Such a vibrant red! My only complaint, and not worth reducing my stars in the rating is the way they clip. I found it a bit difficult to get the wire to clip in the back of my ear. Other's may not have a problem with it though.
