## What reviewers say

**Bose SoundLink Flex (2nd Gen)** — Two whitelisted testers (SoundGuys, TechRadar) reviewed this exact model and both did hands-on testing. Both praise clean, balanced, detailed sound and the rugged IP67 build, but flag minimal upgrades over the 1st Gen, limited EQ options (only four presets), and unremarkable battery life. SoundGuys' standardized 80dB/1m test measured just 7 hours 3 minutes against Bose's 12-hour claim. (2 sourced reviews.)
