Know before you buy
The IP67 rating means the speaker is fully dustproof and can be submerged in up to one meter of water for up to 30 minutes. It is designed to handle accidental drops into a pool or exposure to sand at the beach without sustaining damage.
PositionIQ automatically detects the orientation of the speaker—whether it is lying flat, standing upright, or hanging from its loop—and adjusts the EQ settings to ensure you get the best possible audio performance in any position.
Yes, you can pair the SoundLink Flex with other compatible Bose Bluetooth speakers using the Bose Connect app. This allows you to use Party Mode to play the same audio across multiple speakers or Stereo Mode for a dedicated left-right channel experience.
The 12-hour battery life is an estimate based on average usage. If you consistently play music at maximum volume, you should expect the battery to drain faster than the stated 12-hour limit.
The integrated utility loop is made of durable fabric designed to withstand the rigors of outdoor use. It is sturdy enough to clip onto a carabiner or backpack strap, keeping the speaker secure while you are on the move.
