What customers say
Customers overwhelmingly praise the Bose SoundLink Flex for its superior sound quality, delivering signature Bose clarity and surprisingly deep bass from a compact unit. The speaker's rugged design and IP67 durability are major highlights, making it highly reliable for outdoor use.

Know before you buy
PositionIQ automatically detects the orientation of your speaker and adjusts the EQ settings to ensure you get the best possible audio performance whether it is standing upright, lying flat, or hanging from a bag.
Yes, the speaker features an IPX7 rating, meaning it is fully waterproof and can withstand being submerged in water. It is also dustproof, making it a reliable choice for sandy or rugged outdoor environments.
Absolutely. You can wirelessly link two SoundLink Flex speakers to play in Stereo mode for dedicated left and right channels, or Party mode to play the same audio through both units simultaneously.
The 12-hour estimate is based on typical usage levels. If you consistently play music at maximum volume, you should expect the battery life to be shorter than the stated maximum.
The SoundLink Flex is built with a durable, drop-resistant design intended to handle the bumps and knocks of travel. While it is highly resilient, it is still an electronic device and should be treated with reasonable care.
