Main trade-off
Sennheiser MOMENTUM 5 Wireless
Its current support requires powered analog playback and conflicts with the earlier manual. The repair instructions do not establish US stock of the correct battery.
Head-to-head
Choose Bose QuietComfort Ultra 2 if you already have a compatible Bose Smart Soundbar and want independent headphone and room volume, or you need an inward-folding frame. Choose MOMENTUM 5 if the longer stated ANC battery claim and documented battery replacement matter more. Check US BA 500 availability. Neither is a safe choice for guaranteed unpowered AUX: Bose requires power, and MOMENTUM 5’s documents conflict.
Before you choose
If one person wants a louder soundtrack while another wants a quieter room, Bose documents independent volume between these headphones and a compatible Bose Smart Soundbar through SimpleSync. The room can stay lower while the headphones use a separate level. MOMENTUM 5 may connect to a TV by its supported outputs, but that alone does not establish that the TV keeps its speakers active with independent volume. Check the exact TV before buying. Bose’s advantage here depends on the existing soundbar, not just on choosing a Bose headphone.
What this is based on
Explicit simultaneous-output and volume behavior crossed with a shared-room conflict. No hearing benefit, latency guarantee or universal TV compatibility is claimed.
Main trade-off
Its current support requires powered analog playback and conflicts with the earlier manual. The repair instructions do not establish US stock of the correct battery.
Main trade-off
The TV advantage depends on compatible Bose equipment. The 30-hour ANC claim drops to 23 hours with Immersive Audio, and analog listening needs power.


Momentum 5 vs Bose Ultra 2 for charging less often, sharing a TV room and desk use. See which connection limits matter before choosing either pair.
These premium ANC headphones serve the same commuting and home-listening buyer, but solve different inconveniences. A long battery claim helps away from outlets. A compatible TV setup can make independent room and headphone volume more valuable.
Winner by situation
MOMENTUM 5 lists 57 hours under its test condition. Bose lists 30, or 23 with Immersive Audio. These are not measured equivalents.
Bose documents SimpleSync for this setup. Confirm the exact soundbar is compatible.
Bose folds inward. MOMENTUM 5 does not.
MOMENTUM 5 has conflicting guidance. Bose explicitly requires power.

Someone buying Bose for its spatial presentation should plan around the 23-hour Immersive Audio claim, rather than combining that mode with the 30-hour headline. MOMENTUM 5’s separate 57-hour ANC claim makes it worth considering when charging opportunities matter more than the Bose TV connection. These manufacturer tests are not a measured head-to-head result. Calls, volume and settings change the result. Pick the features you intend to leave on first, then compare the battery figure attached to that mode.
Mode-specific battery claims applied to an outlet-constrained trip. No real-world hours, percentage advantage or equal test conditions are assumed.
For an aircraft seat or older audio source, Bose’s analog input requires power. Its guide permits USB power while using that analog connection, so a compatible power source can support the headphones while the audio cable stays attached. That means packing both cables and a usable power source. MOMENTUM 5’s current support also requires powered analog use, although the earlier manual disagrees. Do not buy either assuming that the audio cable alone guarantees listening after the battery runs down.
Powered-input requirements and Bose’s explicitly documented concurrent charging route. No equivalent MOMENTUM 5 two-cable behavior is inferred.
Check your own setup
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.
Bluetooth listening.

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.

Sennheiser, MOMENTUM 5 Wireless
You want the longer published ANC battery claim and accept a frame that does not fold inward.

Bose, QuietComfort Ultra Headphones (2nd Gen)
You already own a compatible Bose Smart Soundbar and want separate room and headphone volume through SimpleSync.
Meaningful differences
| What changes | Sennheiser MOMENTUM 5 Wireless | Bose QuietComfort Ultra Headphones (2nd Gen) | Why it matters |
|---|---|---|---|
| Shared TV volume | Bluetooth or wired source connection. Check TV output behavior | SimpleSync with a Bose Smart Soundbar supports independent volume | Bose offers a documented answer when two people need different volume, provided the soundbar is compatible. |
| Manufacturer ANC runtime | Up to 57 hours, iPhone at mid volume | Up to 30 hours, or 23 with Immersive Audio | Treat each as its own qualified claim. Do not calculate a measured cross-brand battery advantage. |
| USB playback input | Up to 24-bit 96 kHz in playback-only mode | 16-bit 44.1 or 48 kHz | Source support and microphone use matter. These limits do not rank audible quality. |
| Battery-free analog | Current support requires power. Earlier manual conflicts | Power required. USB power can support analog use | Carry a power plan for either. A cable socket is not proof of passive playback. |
| Starting after a break | Power button required after switch-off | Wearing can wake the headphones from low-power sleep | Bose’s wake behavior can remove a startup step, but automatic sleep differs from manual power-off. |
| Packing and long-term service | No inward fold. Documented BA 500 user replacement | Inward fold. Replacement parts through customer service | Choose the daily packing shape separately from future service plans. |
What you give up
Recommendation switch
Choose Sennheiser MOMENTUM 5 Wireless. MOMENTUM 5 has the longer published ANC claim. Its passive fallback remains uncertain.
Choose Bose QuietComfort Ultra Headphones (2nd Gen). SimpleSync documents the separate-volume route. General TV Bluetooth does not guarantee the same behavior.
What matters in practice
You want to hear a show clearly without raising the room volume for someone else, then take the same headphones away for several days. Bose has a documented shared-TV route with compatible Bose equipment. MOMENTUM 5 puts more emphasis on time between charges and a user battery replacement procedure.
What the facts say
