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 are quality replacements for my ruined old ear pads. They feel just like the originals and fit in well. The installation was a bit frustrating, but that's more Bose's fault.
The reason for only giving 4 stars is that the adhesive on the inner covers was not very well placed so I couldn't stick them down in the exact same places as the original inners. This made installing the ear pads a little bit harder because the inners got in the way, and annoyingly the inner covers now have a crease that slightly sticks out whereas the original ones were spread flat.
That said, I would still buy these again as they are great value.
