The Smart Ultra Soundbar takes its updates through the Bose app, which needs a current release. Bose's soundbar release notes show that firmware 10.0.26 added Saved Groups and Atmos streaming over Amazon Music and Chromecast, and that HDMI-CEC improvements make the soundbar default to the TV source when the TV turns on. The app release of 25 August 2026 needs iOS 17 or later, or Android 13 or later.

ReversibleOpen the soundbar in the app and read its firmware version, comparing it with Bose's software and firmware page.

Model-specific
What is true of this model and not of its siblings
- Light bar colors
- White pulsing means rebooting, blue pulsing means ready to connect Bluetooth, amber solid means setup mode and ready for Wi-Fi, green pulsing means ready for setup or Recovery mode, and red solid means a system error.
- Grouping
- Group from the Bose app's Group button, adding all speakers with + Add All or choosing individual ones; only one Bluetooth device can join at a time and Saved Groups have existed since 9 April 2025.
- Factory restore
- Remove the soundbar from your Bose account first, then hold Play/Pause and Volume - for five seconds. The light bar blinks twice, the soundbar reboots and glows amber.
- What the Ultra is
- Nine speakers (three tweeters and six woofers), Dolby Digital, Digital Plus, TrueHD and Atmos, one HDMI eARC input and one optical input, a built-in microphone, Alexa built in and Google compatibility, in Black or Arctic White.
- Build and size
- The Ultra is 41.34 inches wide, 4.33 deep and 2.36 high and weighs 12.7 pounds unpackaged, in Black or Arctic White. Inside are nine speakers: three tweeters and six woofers. Its inputs are one HDMI eARC connection and one optical, with Wi-Fi, Bluetooth, AirPlay 2 and Google Cast for streaming.
- Setup with ADAPTiQ
- Setup in the Bose app includes the ADAPTiQ headset that ships in the box, which measures the room so the soundbar can tune its sound. If the soundbar is moved to a new position, repeat the ADAPTiQ step so the tuning matches the new place rather than the old one.
- Setup mode and recovery
- Holding Mute and Bose Music on the remote for five seconds puts the soundbar into setup mode with a glowing amber light bar. Green pulsing shows it is ready for setup or entering Recovery mode, and red solid means a system error, for which Bose has a separate light-bar-is-red troubleshooting article.
- Bluetooth choice
- Bose says it used proven earlier Bluetooth hardware in the Ultra because the newer 5.1 revision made no difference to the A2DP stereo audio profile, and that hardware with thorough field testing brings dependable interoperability. The soundbar supports A2DP, AVRCP and Bluetooth Low Energy, with about 30 feet of range.
Stop boundary
When this stops being a self-service repair
- !If updates fail on two networks after a reset, request service
- !If the soundbar reboots repeatedly, unplug it and contact Bose
