Water & Dust Proof (IP67-Rated): The Bose SoundLink Flex (2nd Gen) portable Bluetooth speaker has been rigorously tested to meet an IP67 rating, making it water and dust proof. The SoundLink Flex (2nd Gen) is completely dust-tight and can withstand water splashes (including rain & snow), as well as the pressure of being immersed in water up to 3.3' (1m) deep - for up to 30 minutes. The SoundLink Flex (2nd Gen) speaker is the perfect outdoor music companion with its rugged design that is able to withstand water, dust, and a few bumps and bruises along the way. It even floats, so it won't sink to the ocean floor if it falls off your paddleboard. The speaker is also protected against dust, so you don't need to worry if it gets sandy at the beach.

• Rugged Exterior: With its powder-coated steel grille and silicone exterior, the SoundLink Flex (2nd Gen) was purpose-built with durable materials to withstand the outdoor elements. Its tough exterior can also withstand almost any mishap, like a fall to the floor. The grille's thick coat of powder gives the speaker a rugged texture that can withstand whatever your day throws at it. The powder coat won't peel or flake, and it's resistant to rust corrosion and UV light.
• Waterproof Speaker Material: To ensure further protection from water, dust, and debris, the Bose SoundLink Flex (2nd Gen) Bluetooth speaker's transducer and passive radiators underneath the steel grille are built with rugged, waterproof materials and sealed tightly to the speaker’s housing.

Audio Technologies: The SoundLink Flex (2nd Gen) is packed with state-of-the-art engineering and exclusive Bose & Qualcomm audio technologies. The speaker's custom drivers, digital signal processing (DSP) technologies, and proprietary algorithms all work together to ensure optimal sound quality wherever you are. Together, these technologies enable the SoundLink Flex (2nd Gen) to deliver an exceptional music experience with sound that is crisp, clear, and free of distortions.

• Custom-Designed Drivers: The SoundLink Flex (2nd Gen)'s innovative transducer and passive radiators are custom designed specifically for the portable Bluetooth speaker. There is one 2" transducer and two small passive radiators (one front and one rear facing) that deliver the clearest possible sound and well-balanced midbass for a speaker system of its size.
• PositionIQ Technology: The SoundLink Flex (2nd Gen) also features PositionIQ technology, which automatically detects its orientation and optimizes the EQ to ensure natural, lifelike sound no matter the orientation. Using a built in sensor, the SoundLink Flex (2nd Gen) detects its orientation and automatically adjusts its EQ to deliver an uncompromised, high-fidelity audio experience whether it's vertical, lying flat, or horizontal.
• Snapdragon Sound: Snapdragon Sound technology is designed to deliver "end-to-end" premium wireless sound from your mobile device to the Bose SoundLink Flex (2nd Gen). With SnapDragon Sound, you'll hear every detail that your wireless music has to offer, plus ultra-low latency and glitch-free connectivity. To experience Snapdragon Sound, you'll need a Bluetooth source device (such as an Android Smartphone or Table) that support aptX adaptive.

Bluetooth 5.3: The Bose SoundLink Flex (2nd Gen) features built-in Bluetooth 5.3 with support for wireless audio streaming (A2DP) and control (AVRCP). It also provides multi-device pairing and two phone connection. The SoundLink Flex (2nd Gen)'s Bluetooth connection is capable of stable wireless operation at up to 30' (9m).

• Voice Guided Multi-Device Pairing: Voice prompts talk you through Bluetooth Secure Simple Pairing (SSP), making it easy to wirelessly connect your Bluetooth-enabled source device to the Bose SoundLink Flex (2nd Gen) speaker. The SoundLink Flex (2nd Gen) keeps track of the last 8 devices to have paired and connected with it, dropping the least recently used when a new one is paired. When in Bluetooth mode, the SoundLink Flex (2nd Gen) searches for and connects to the two most recently connected active Bluetooth-enabled devices. The speaker will only receive audio from one device at a time. When the first device stops playing, the other can start.
• Wireless Audio Streaming: Thanks to the support for Bluetooth A2DP & AVRCP, you can stream stored music, music apps and other audio content from your Bluetooth source device to the Bose SoundLink Flex (2nd Gen) speaker. You also get basic playback controls such as Play/Pause, Volume Up/Down, and Skip Track from the SoundLink Flex (2nd Gen)'s top-panel buttons. You'll still use your Bluetooth source device for advanced music browsing and to view song/artist/album information.

Bose App: The Bose app (for Apple iOS and Android OS) lets you setup and control the SoundLink Flex (2nd Gen) speaker from your compatible smartphone or tablet device. Using the app you can manage all of your connected Bluetooth source devices with an intuitive graphic interface that lets you switch between devices whenever you want. Withing the Bose app, you can also personalize your settings, pair multiple speakers, unlock product features, keep your software up to date, and more.

Stereo & Party Modes: The SoundLink Flex (2nd Gen) offers a Stereo Mode and Party mode which allows you to wirelessly sync two Bose SoundLink Flex (2nd Gen) speakers together. Party Mode lets you connect two Bose Flex (2nd Gen) speakers to play the same audio in perfect sync, while Stereo Mode, enables a stereo audio experience via two Bose SoundLink Flex (2nd Gen) speakers.

Rechargeable Battery: The Bose SoundLink Flex (2nd Gen) portable Bluetooth speaker features a built-in rechargeable lithium-ion battery. In typical usage, the built-in rechargeable battery lasts up to 12 hours. Battery performance varies with the content played and volume at which it is played. An auto-off timer conserves the battery when the speaker is operating only on battery power. The speaker switches off when audio has stopped and buttons have not been pressed for about 20 minutes. When the speaker is unplugged and unused for more than three days with a remaining charge of less than 10%, it enters battery protection mode to preserve battery power.

• Because SoundLink Flex (2nd Gen) employs a USB-C charging port, it can receive power from nearly any USB power source. For best results, use the included USB-C to USB-A cable with a USB power source rated for at least 1.5A (not included and sold separately - see Accessories Tab). Please note that some power sources with less than 1A of current may charge SoundLink Flex (2nd Gen) more slowly than the recommended power sources, and may not be able to keep up with the power consumed while the speaker is operating.
• While not playing music, much of the SoundLink Flex (2nd Gen)’s battery charge can be recovered in approximately 4 hours when using a 1A USB power source. With a stronger 1.5A power source, charging time may be closer to 3 hours. Charging from alternate USB power sources or when playing music may take longer.

Finger Strap: You can use the integrated strap as a finger loop to easily carry the speaker. You can also attach it to a carabiner (not included).

Placement Options: For optimal performance, place the back of the Bluetooth speaker near, but not directly against a wall. Bass response decreases as you move your speaker away from a wall. You should keep other wireless equipment at least 3'away from the speaker to prevent interference. Wireless performance can be affected by obstacles such as walls or metal, interference from WiFi or other wireless devices and device manufacturers' Bluetooth implementations.
