What is true of this model and changes how you fix it
- Official specificationsBluetooth 5.3, IP67 rated (dust and waterproof; it floats). Up to 12 hours battery, roughly 4 hours to fully charge, USB-C. Silicone-wrapped body.
- Type — portable Bluetooth speaker (battery)A rugged, waterproof (IP67) portable BLUETOOTH speaker with a battery — no WiFi. Pairs directly to a phone over Bluetooth; battery, charging and Bluetooth-pairing symptoms apply, not any WiFi/app-streaming ones.
- Battery & chargingAround 12 hours rated; loud volume shortens it. Charges by USB-C; if it starts low it was not fully charged. A speaker that will not turn on usually needs charging.
- PairingBluetooth pairing via the button or the Bose app; if it will not connect, clear the old pairing from the phone and from a competing device it auto-reconnects to.
- Bluetooth and pairing memoryBluetooth 5.3 with about 30 ft of range. It remembers up to 6 paired devices and connects to the two most recently used when powered on.
- Clearing pairingsTurn the speaker on and hold the Bluetooth button for 15 seconds to clear the paired-device list, or remove devices in the Bose app.
- Battery, rating and connectionThe second-generation SoundLink Flex is rated IP67 for water and dust, plays up to 12 hours, charges over USB-C in about 4 hours and connects over Bluetooth 5.3.
- Pairing checksBose's pairing guidance is the same for its portable speakers: put the speaker in pairing mode until the light blinks blue, keep the phone within about 30 feet and move away from other Bluetooth devices.

Exact questions
Questions that only have an answer for the Bose SoundLink Flex (2nd Gen)
My Bose SoundLink Flex won't pair or keeps connecting to the wrong device.+
Bluetooth speakers auto-reconnect to the last device they saw, so it may be grabbing another phone or tablet nearby — turn Bluetooth off on that device, then pair to the one you want. To pair fresh, hold the Bluetooth button until it is in pairing mode and select it on your phone; use the Bose app to manage paired devices. Clearing the speaker from a phone's Bluetooth list and re-adding it fixes most stubborn pairings.
How long does the SoundLink Flex 2nd Gen battery last?+
Bose quotes up to 12 hours and a 4 hour charge over USB-C.
