Yes, the noise cancelling of the Bose QuietComfort Ultra headphones also works without Bluetooth. The noise-cancelling technology uses both active and passive noise correction, which work independently of the Bluetooth connection. The headphones can also be connected via the audio cable and continue to provide noise cancellation as long as the headphones are switched on.

The Bose QuietComfort Ultra headphones support various Bluetooth aptX profiles:

- aptX Lossless: these headphones are one of the few products that support aptX Lossless, which enables the transmission of CD-quality audio. However, this requires a compatible Android device with a Qualcomm Snapdragon 888 or newer processor.

- aptX Adaptive: When the headphones are connected to a Snapdragon Sound certified device, the aptX Adaptive Bluetooth codec is automatically used to ensure the best sound quality, connection stability and latency.

- LE Audio: The headphones also support LE Audio, which may be useful in public spaces and venues in the future as more LE Audio transmitters become available.
