Bose's article for a SoundLink Max whose Bluetooth keeps disconnecting starts with range (about 33 feet or 10 meters, reduced by walls, doors, pockets and other Bluetooth devices), then reboots the phone, clears the speaker's paired-device memory, and on Windows unticks Allow the computer to turn off this device to save power for the Bluetooth adapter. It also suggests disconnecting nearby electronics that might interfere and trying a different Bluetooth device.

Model-specific
What is true of this model and not of its siblings
- Bluetooth range
- About 33 feet (10 meters), reduced by walls, doors, metal and other Bluetooth devices.
- Bluetooth light
- Slow blue blinking is ready to connect, quick blue blinking is connecting, solid white is connected and two white blinks confirm the paired-device list was cleared.
- Two resets
- Hold Power up to 30 seconds with the USB-C cable unplugged for a reset that keeps settings. Hold - and + together for 15 seconds until the power light blinks white for 3 seconds for a factory restore.
- What the Max is
- A portable speaker with one 0.79-inch tweeter and two 2.5-inch midranges, an IP67 rating, Bluetooth 5.4 with A2DP, AVRCP and BLE, a 3.5 mm input, a USB-C port and no microphone. It comes in Black, Blue Dusk and Citrus Yellow.
- Checking battery level
- The Power light glows according to the battery level, so it doubles as a gauge, and the Bose app also shows the level on the product control screen. Solid white means full or powered on, solid amber means low and blinking amber means it needs charging, which is the cue to plug in the USB-C cable.
- Support paths
- Bose's support site lists the Max under Help Articles, Repair or replace, Manuals and downloads, Accessories and video guides. Before starting a repair have the serial number to hand, because Bose cannot process a repair, exchange or trade-in without a valid serial number or date of manufacture code, though it can still give troubleshooting help.
- Build and finish
- The SoundLink Max is built from aluminum, fabric, nylon, plastic, silicone, steel and rope, with a rope handle for carrying. It comes in Black, Blue Dusk and Citrus Yellow and carries an IP67 rating, which covers dust and brief immersion but does not make the USB-C port safe to charge while wet.
- First-time setup
- Install the Bose app, allow Location and Bluetooth access when asked so the app can find the speaker, sign in or create a Bose account, then hold the Bluetooth button until you hear Ready to connect and the light pulses blue. In the app choose the plus box on My Bose, then Headphones, Earbuds, Portable Speakers and Frames.
Stop boundary
When this stops being a self-service repair
- !If it disconnects from every device beside the phone after a factory restore, request service
- !If the power light shows an alternating white and amber error, contact Bose customer service
