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.
Excellent product !! Totally value for money. Sound and voice quality is very good either when listening to music or while talking on con-calls. The product can also be used on mobile phones only if not with computer. Very modular !! Extremely happy with the product !!
