Our Verdict

Anker Soundcore 3

Bose SoundLink Flex

The Bose SoundLink Flex is a better speaker overall than the Anker Soundcore 3. The Bose has a better-balanced sound profile and a much better build quality than the Anker. However, the Anker can get a bit louder with less compression present at max volume, resulting in cleaner audio at louder volumes. However, the Anker has a longer-lasting battery life of over 13 hours. Battery life can vary depending on your usage, and your experience may differ.
