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.
Worked well with my phone for a couple of weeks and then one earbud stopped working. Three days later the second one also gave up. Disappointed with the product as I was hoping to not have to buy another pair of earphones for at least three to four months.
