Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: 887612
What that covers: Bose product; Bluetooth multipoint, app generation, wired input and spatial/ANC features vary.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

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 & charging: Around 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.
Pairing: Bluetooth 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.
Power path: Internal or removable battery. Every capability that costs current — night vision, higher stream quality, longer recordings, frequent events — is paid for in runtime, so a change in behaviour after a settings change is usually a power consequence rather than a fault. Cold weather reduces usable capacity sharply.

Exact questions

Questions that only have an answer for the Bose SoundLink Flex (2nd Gen)

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

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.

Structured depth, not empty permutations
