Bose SoundLink Max speaker plays from only one side or channel

A SoundLink Max playing from only one side is either a stereo-link setting or a source problem, because a single Max is one speaker with a tweeter and two midranges. Bose's Speaker Link shortcut can put two Max speakers in Stereo mode (left and right) or Party mode, and its advice for linked speakers is to enable the link shortcut on both, name them differently in the app, update both and keep them within Bluetooth range. To swap between Stereo and Party, press the Shortcut button once.

Check the shortcut

Name them apart

If both speakers are Max models, give them different names in the Bose app so you can tell which one you are controlling.

Model-specific

What is true of this model and not of its siblings

Bluetooth details: The speaker uses Bluetooth 5.4 with A2DP for stereo audio, AVRCP for remote control and Bluetooth Low Energy, over a range of about 33 feet (9 to 10 meters). Clearing its memory of paired devices takes a 15 second hold of the Bluetooth button, after which you hear that the device list is cleared.
Windows and Echo Dot tips: On Windows 10 the speaker can appear twice; pick the entry with the speaker or headphones icon and never the one starting LE. If an Amazon Echo Dot has paired with the speaker before, remove all other devices from the Dot's Bluetooth memory in the Alexa app so the two do not keep looking for absent devices.

Stop boundary

When this stops being a self-service repair

!If a single unlinked Max plays one channel only, request service from Bose
!If the Shortcut light never turns solid white on either speaker after a reset, contact Bose Support
