Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
i really like this headphone,good addition to my new Hi Re player AW-45 my only deslike is that the rear cup will be larger,but they are very good in price and quality !!!!!!
Good headphones for the price but not the best that Sony can offer... Expected a bit more sound quality but they are great compared to the price... Microphone is very clear as well!
