The SoundLink Flex Bluetooth speaker plays astonishing sound wherever you are. The audio is crisp, balanced, and free of distortions. Plus, the powerful wireless speaker can play over ambient noise while you’re entertaining, and project loudly during outdoor activities.

Whether the Soundlink Flex is upright, hanging, or on its back, PositionIQ technology detects its position and auto ensures a natural, lifelike sound.

This portable speaker meets IP67 waterproof standards, is crafted with waterproof materials, and is sealed to keep out dust & debris; it even floats.

The powder-coated steel grille and silicone exterior give the speaker a rugged texture to withstand nearly anything including peeling and corrosion.

The Soundlink Flex has a rugged utility loop that lets you secure it to almost anything, anywhere. Attach it to a carabiner and hang it from anywhere!

Purpose-built waterproof speaker

The powder-coated steel grille and silicone exterior give the outdoor speaker a rugged texture that can withstand nearly anything. The grille won’t peel or flake, and resists corrosion and UV light.

Built-in microphone

You can make and receive phone calls through the SoundLink Flex Bluetooth speaker, and just one button accesses your phone's Siri or Google Assistant voice input if your phone is out of reach.
