Our Verdict
Amazon Echo Buds True Wireless 2019 (1st generation)
Amazon Echo Buds True Wireless 2021 (2nd generation)
The Amazon Echo Buds True Wireless 2019 (1st generation) and the Amazon Echo Buds True Wireless 2021 (2nd generation) have different strengths, so you may prefer either, depending on your needs. The first generation Echo Buds have a significantly better noise isolation performance. Their case also holds roughly five extra charges, while the Gen 2's case only holds two. On the other hand, the Gen 2's case is more compact and charges with a USB-C connection instead of micro-USB. The earbuds are also smaller and more comfortable. The Gen 2's integrated mic has a much better recording quality as well.
