Only aggregate ratings are available, with a small number of ratings and all in the five-star category. This is limited evidence and does not reveal customers' reasons or confirm fit, sealing, or durability. For a replacement diaphragm, matching the listed 54 mm size and single-ear design is more useful than inferring compatibility from the rating.
