Bose SoundLink Flex II Portable Bluetooth Speaker - Sandstone

Meet the Bose SoundLink Flex II in Sandstone, a portable Bluetooth speaker that pairs rugged durability with surprisingly rich mono sound. Unlike typical compact speakers that compromise on bass or clarity, the Flex II uses Bose PositionIQ technology to automatically adjust the audio profile whether it’s standing upright, lying flat, or hanging from its integrated utility loop. The soft-touch silicone exterior and powder-coated steel grille shrug off drops, dust, and water, making it a reliable companion for outdoor adventures or kitchen countertops.

Highlights

• IP67 dust and water resistance — fully protected against dust and submersion in up to 1 meter of water for 30 minutes.
• Up to 12 hours of battery life per charge, with USB-C charging (approximately 4 hours to full).
• Built-in microphone for clear speakerphone calls and one-touch access to your phone’s voice assistant.
• Pair two Flex II speakers for stereo mode or link multiple units for Party Mode via the Bose Connect app.
• Engineered to withstand drops and bumps, with a utility loop for easy carrying or hanging.

In daily use

The SoundLink Flex II is ready for anything. Its compact size and lightweight build slip easily into a backpack or tote, while the utility loop clips onto a carabiner or hook. The controls are straightforward: power, volume, Bluetooth pairing, and a multifunction button for play/pause and call management. A row of LED indicators shows battery level and Bluetooth status. The speaker remembers up to eight paired devices, so switching between a phone and tablet is seamless. When you need a bigger soundstage, pair two Flex II units in stereo or sync multiple speakers for a whole-home or outdoor party setup.
