Our Verdict

Bose SoundLink Revolve+ II

Bose SoundLink Flex

The Bose SoundLink Revolve+ II and the Bose SoundLink Flex perform similarly. The Revolve+ II offers a wider and more natural-sounding soundstage thanks to its 360-degree design. It also has a longer-lasting battery life, though that can vary depending on your usage. On the other hand, the Flex is smaller, and voice assistants from your paired smartphone are better at understanding your commands from far away and in noisy environments. It's better built, with an IP67 rating for dust and water resistance, and its default sound profile is also a bit more balanced.
