If you’re searching for a Bose SoundLink Flex Portable Speaker 2nd Gen review, you’re likely trying to figure out how much of an upgrade it really is—and whether it’s worth buying over the first version.
We tested the Bose SoundLink Flex Portable Speaker (2nd Gen) in real-world situations, including indoor listening, outdoor use, and day-to-day portability, to see how it performs where it matters most.
If you want the bottom line:
The Bose SoundLink Flex Portable Speakers 2nd Gen is one of the best portable speakers we tested and is a refined upgrade from the 1st generation that improves battery performance, durability, and overall usability while maintaining the balanced sound Bose is known for.
But to really understand what’s changed, let’s start with a quick comparison.
Comparing the Bose SoundLink Flex (2nd Gen) vs SoundLink Flex
If you’re upgrading, this is the part that matters most. The 2nd Gen version builds on the original SoundLink Flex by improving everyday usability rather than completely redesigning the product.
| Feature | Bose SoundLink Flex | Bose SoundLink Flex (2nd Gen) |
|---|---|---|
| Battery Life | Up to 12 hours | Up to 12 hours (more stable performance over time) |
| Charging Port | USB-C | USB-C (improved charging efficiency and consistency) |
| Bluetooth Version | Bluetooth 4.2 | Bluetooth 5.3 (more stable connection, better range) |
| Water & Dust Resistance | IP67 (waterproof and dustproof) | IP67 (same rating, improved durability in daily use) |
| PositionIQ Technology | Yes | Yes (more refined sound adjustment based on orientation) |
| Sound Performance | Clear and balanced for its size | More consistent sound output across different environments |
| Build & Materials | Rugged silicone exterior | Similar build with improved finishing and durability |
| Real-World Use | Great for casual outdoor use | Better suited for everyday use with improved reliability |

For most users, the Bose SoundLink Flex (2nd Gen) is a type of speaker that feels like a refined version of an already reliable speaker. If you own the first version, the upgrade is more about consistency and usability rather than a major leap.
