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.
These headphones work well, but they are a compromise. When playing music, the sound is ok, not great, but for me it is an easy tradeoff for not having anything stuck in my ears. These are not good for blasting music. If the volume is too high, there can be an uncomfortable buzzing sensation, but this can be avoided by adjusting volume or repositioning. I have been told that the sound quality when I talk on the phone is great – others wouldn't guess I was using headphones. The controls are fairly simple to use, but the button action beeps are quite loud.
