The catch
Sennheiser MOMENTUM 5 Wireless
Current support calls for powered analog playback, which conflicts with the earlier manual. The repair instructions do not establish that the correct battery is in stock in the US.
Side by side
Momentum 5 vs Bose QuietComfort Ultra 2: Compatible Smart bars can share TV audio with Bose
Quick verdict
Bose QuietComfort Ultra 2 fits you if you already own a compatible Bose Smart Soundbar and want headphone volume separate from room volume, or if you need a frame that folds inward. MOMENTUM 5 fits you if the longer stated ANC battery claim and a documented battery replacement matter more, but check US BA 500 availability first. For guaranteed unpowered AUX, neither is safe: Bose requires power, and MOMENTUM 5’s documents contradict each other.
Before you buy
Why, and what it costs you
Wanting different TV volumes does not mean watching in different rooms
When one person wants a louder soundtrack and another wants a quieter room, Bose documents independent volume between these headphones and a compatible Bose Smart Soundbar via SimpleSync. The room can stay lower while the headphones run at their own level. MOMENTUM 5 may connect to a TV through its supported outputs, but that alone does not establish that the TV keeps its speakers active with independent volume. Check the exact TV before you buy. The Bose advantage here depends on the soundbar you already have and not merely on picking a Bose headphone.
Where this comes from
Documented simultaneous-output and volume behavior set against a shared-room conflict. It claims no hearing benefit, latency guarantee or universal TV compatibility.
The catch
Bose QuietComfort Ultra Headphones (2nd Gen)
The TV advantage depends on compatible Bose equipment. With Immersive Audio the 30-hour ANC claim drops to 23 hours, and analog listening needs power.
Sennheiser MOMENTUM 5 Wireless
- Why pick it
- The longer published ANC battery claim appeals to you, and a frame that doesn’t fold inward is acceptable.
- A battery replacement procedure matters to you once you have checked US BA 500 availability. Battery-free AUX is not something to depend on.
- The catch
- Current support calls for powered analog playback, which conflicts with the earlier manual. The repair instructions do not establish that the correct battery is in stock in the US.
Bose QuietComfort Ultra Headphones (2nd Gen)
- Why pick it
- A compatible Bose Smart Soundbar is already yours, and you want room volume and headphone volume kept apart through SimpleSync.
- A travel frame that folds inward and USB listening during charging are on your list. Analog playback still requires power.

What this page compares
Momentum 5 and Bose Ultra 2 compared on charging less often, sharing a TV room and desk use. Find out which connection limits matter before you commit to either pair.
Both premium ANC headphones target the same commuting and home-listening buyer yet address different annoyances. Away from outlets, a long battery claim helps. With a compatible TV setup, independent room and headphone volume can matter more.

How we worked this out

You cannot get the most immersive mode and the longest trip rating at once
If you are buying Bose for its spatial presentation, plan around the 23-hour Immersive Audio claim and do not pair that mode with the 30-hour headline. The separate 57-hour ANC claim for MOMENTUM 5 makes it worth a look when charging opportunities count for more than the Bose TV connection. These manufacturer tests are not a measured head-to-head result, and calls, volume and settings change what you get. First decide which features you plan to leave on, then compare the battery figure tied to that mode.
How we worked this out
Battery claims tied to a mode, applied to a trip with limited outlets. It assumes no real-world hours, percentage advantage or equal test conditions.
A charging cable may save Bose analog listening, yet it makes for a two-cable setup
On an aircraft seat or with an older audio source, the analog input on Bose needs power. Its guide allows USB power during that analog connection, so a compatible power source can run the headphones while the audio cable stays plugged in. That means packing both cables and a usable power source. Current support for MOMENTUM 5 also requires powered analog use, although the earlier manual disagrees. Do not buy either one assuming the audio cable by itself guarantees listening once the battery runs down.
How we worked this out
Powered-input requirements alongside the concurrent charging route that Bose documents outright. No equivalent two-cable behavior is assumed for MOMENTUM 5.
Plug in your setup
Which headphones suit the way you listen?
Start with how you listen. Charging over USB is not the same as playing audio over USB, and some headphones need power even on a cable. These answers are placeholders until you apply your own.

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

Spec by spec
Where they really differ
| Spec | Sennheiser MOMENTUM 5 Wireless | Bose QuietComfort Ultra Headphones (2nd Gen) | In practice |
|---|---|---|---|
| Shared TV volume | Bluetooth or wired source connection. Check TV output behavior | SimpleSync with a Bose Smart Soundbar supports independent volume | When two people need different volumes, Bose has a documented answer, as long as the soundbar is compatible. |
| Manufacturer ANC runtime | Up to 57 hours, iPhone at mid volume | Up to 30 hours, or 23 with Immersive Audio | Each is a qualified claim of its own. A measured cross-brand battery advantage should not be calculated. |
| USB playback input | Up to 24-bit 96 kHz in playback-only mode | 16-bit 44.1 or 48 kHz | Both source support and microphone use count. None of these limits ranks audible quality. |
| Battery-free analog | Current support requires power. Earlier manual conflicts | Power required. USB power can support analog use | Plan for power with either one. Having a cable socket does not prove 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 save a startup step, yet automatic sleep is not the same as manual power-off. |
| Packing and long-term service | No inward fold. Documented BA 500 user replacement | Inward fold. Replacement parts through customer service | Decide on the daily packing shape apart from any future service plans. |
Trade-offs
What each pick costs you
With Sennheiser MOMENTUM 5 Wireless
- Independent TV speaker and headphone volume is not established by a general Bluetooth connection alone. Check how the television behaves on output.
With Bose QuietComfort Ultra Headphones (2nd Gen)
- USB playback accepts input at 16-bit 44.1 or 48 kHz. Over that connection, a higher-resolution file does not arrive unchanged at its original higher sample rate.
Change of plan
When the answer changes
Your main constraint is chances to charge, and the larger frame is fine
Go with Sennheiser MOMENTUM 5 Wireless. The longer published ANC claim belongs to MOMENTUM 5. Its passive fallback is still uncertain.
Your compatible Bose soundbar has to serve two listeners at different volumes
Go with Bose QuietComfort Ultra Headphones (2nd Gen). The separate-volume route is documented for SimpleSync. General TV Bluetooth does not guarantee the same behavior.
Decision guide
Before you buy
Say you want to hear a show clearly without turning up the room volume for someone else, and then travel with those same headphones for several days. Bose documents a shared-TV route using compatible Bose equipment. MOMENTUM 5 leans toward time between charges and a battery replacement procedure the user can follow.
What this page can’t tell you
- We claim no comparative test of sound, comfort, noise cancellation or voice isolation. SimpleSync depends on specific equipment. Passive playback on MOMENTUM 5 is still uncertain.
