Bose 865983-0100-cr SoundLink Flex Bluetooth Waterproof Speaker

The Bose SoundLink Flex is engineered around a custom transducer and proprietary PositionIQ orientation sensing — a combination that addresses the core problem with portable speakers: audio quality degrades significantly when a speaker is placed on its side, hung from a strap, or set on an irregular surface. The PositionIQ system measures the speaker's physical orientation and dynamically adjusts output parameters to maintain consistent bass extension and tonal balance regardless of how it's positioned. The IP67 waterproof rating goes beyond splash-proofing into genuine submersion tolerance at 1 meter depth, and the speaker's buoyant construction means accidental drops into water don't result in a loss. Corrosion and UV resistance extend the outdoor durability profile beyond what the waterproof rating alone covers.

The 12-hour lithium-ion battery covers a typical outdoor use day at moderate volume, with USB-C charging providing a universal replenishment method. Bluetooth connectivity covers a 30-foot working range with built-in microphone support for hands-free calls — a single button accesses Siri or Google Assistant. The Bose Connect app manages firmware updates, stereo/party pairing mode configuration, and feature customization. This is a speaker designed for users who move between environments — a studio desk, a backyard, a kayak — and need audio hardware that doesn't require accommodation for where it's placed or what conditions it encounters. The Stereo Mode pairing with a second SoundLink Flex unit is the path to genuine two-channel listening at this form factor.
