PositionIQ Technology
A key feature is Bose PositionIQ technology. The speaker automatically detects its orientation and adjusts the audio to maintain optimal sound whether it is placed upright, lying on its back, or hanging from its utility loop. Bose
IP67 Waterproof & Dustproof Design
The SoundLink Flex (2nd Gen) carries an IP67 rating, making it both dustproof and waterproof. Its rugged silicone-wrapped construction is designed for outdoor and portable use. Bose
Battery & Charging
The built-in rechargeable lithium-ion battery provides up to 12 hours of playback under Bose’s specified moderate-volume conditions. Charging from 0–100% takes approximately 4 hours with a 5V/1.5A (7.5W) USB-C power supply. Actual battery life varies with volume, content and environmental conditions. Bose Support
Stereo & Party Modes
Two compatible Bose speakers can be connected for larger sound. Stereo Mode provides separate left and right channels when using two identical SoundLink Flex (2nd Gen) speakers, while Party Mode allows compatible speakers to play together. Bose SimpleSync is also supported. Bose Support
