When Amazon introduced its 2nd-generation Echo Buds in 2021, the company redesigned them to address nearly every issue with its first attempt. They had true active noise cancellation (ANC), better sound and a smaller size. While those ANC Echo Buds are sticking around, Amazon took a much different approach for its third version. It opted to move from the mid-range to a low-cost model with an all-new design that covers most of the basic features you’d expect.
