Our verdict
Where it wins
- IP67 dust and water rating, and Bose says it floats if dropped in water
- Built-in microphone doubles as a speakerphone, which the JBL Flip 7 lacks
- PositionIQ senses how the speaker is oriented and adjusts output accordingly, per Bose
Where it loses
- Bose rates the battery at 12 hours, below JBL's 16 hour claim for the similar-size Flip 7
- List price of $159 is high for the size class, so it is only good value on sale
- Stereo playback requires buying a second compatible Bose speaker
The second-generation Flex adds Bluetooth multipoint and a shortcut button to what was already a popular rugged speaker. It suits people who take calls on their speaker and want the flat form factor that fits in a bag pocket. At the frequent $129 sale price it is competitive; at the full $159 the JBL Flip 7 and cheaper Sony and Soundcore options make more sense.

Common questions
What changed from the first SoundLink Flex?
The 2nd Gen model moves to Bluetooth 5.3 with multipoint for switching between two devices, and adds a programmable shortcut button. The size, IP67 rating and 12 hour battery rating carry over.
Can I take calls on it?
Yes. It has a built-in microphone and works as a speakerphone when paired to a phone.
Does it float?
Bose says the speaker floats and carries an IP67 rating for dust and water immersion, so a drop in a pool is survivable.
