Head-to-head
Sonos Ace vs Bose QuietComfort Ultra 2nd Gen: Ace shares a compatible Sonos TV setup
The short answer
Choose Sonos Ace for TV Audio Swap with a supported Sonos soundbar. Bose Ultra 2nd Gen suits a lighter folding design when that TV connection is unnecessary.
Before you choose
The reasoning and the trade-offs
Plan charging around your listening day
At eight hours of listening per day, Sonos Ace claims the equivalent of 3.8 days and Bose QuietComfort Ultra Headphones (2nd Gen) 3.8 days in standard ANC mode. Leave headroom for real use.
What this is based on
Claimed ANC runtime / 8 hours per day. Inputs 30 and 30 hours. This is a planning conversion of separate manufacturer maximums, not a measured endurance result.
Main trade-off
Bose QuietComfort Ultra Headphones (2nd Gen)
Analog playback still needs power, unlike standard QuietComfort models.

Before you choose
How they fit your plans
Bose has a documented return path from USB to the phone
With computer audio arriving over USB, Bose lets you use its Bluetooth/Power button to return to a previously connected Bluetooth device. Sonos disables Bluetooth while a wired source is connected, so reaching the phone requires leaving that wired configuration. Choose Bose if manually switching between those two sources is part of the desk routine. Choose Ace if the wired session can stay separate from phone use.
Facts behind this advice
Bose documents selecting Bluetooth and switching back to USB with the button. Sonos requires disconnecting the USB-C cable before Bluetooth and app settings become available. Neither promises simultaneous source mixing.
A lost aircraft cable has a model-specific replacement cost
Ace needs the correct Sonos analog cable, since Sonos says third-party USB-C to 3.5 mm leads are incompatible. Bose uses its documented 2.5 mm-to-3.5 mm analog route, but still needs power and disables earcup microphone pickup in that mode. Choose Ace with its approved spare cable planned, or Bose when its documented analog arrangement better matches your kit. A generic USB-C adapter should not be assumed interchangeable.
Facts behind this advice
The decision concerns replacement compatibility and operating requirements rather than cable durability. Sonos explicitly rules out third-party analog leads. Bose’s AUX section specifies the connectors, power requirement and disabled microphones.
Winner by situation
Start with what you need it to do
Use a supported Sonos soundbar for private TV
TV Audio Swap works with supported Sonos soundbars and the required software. It is a more concrete reason to buy Ace than assuming it behaves like a Wi-Fi room speaker.

Which headphones work with the way you listen?
Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.

Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.
