Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
great value, good sound. Note: at first they sounded tinny and had some distortion BUT as with most speakers of any type after playing them with volume at mid level for a few hours the sound cleared up and began to “sing”. Now they can handle a lot more than I expected for the price I paid.
