Choose the feature and the generation together

This review covers the first-generation QuietComfort Ultra Headphones, not a newer generation or the Ultra earbuds. The reason to investigate this model in our shortlist is a specific interest in Bose Immersive Audio. CustomTune personalization is also part of its documented feature set.

We would make the feature decision before considering a particular offer. If spatial listening is something you want to explore, this model answers that interest. If it is not important, a different model may make more sense for your charging routine or device requirements.

Immersive listening is a preference to explore

Bose describes Immersive Audio as a spatial presentation. Whether that presentation makes your favorite music or other content more enjoyable is a personal question. We have not conducted a listening test and would not equate the availability of a mode with universally better sound.

Our advice is to try the feature with familiar content when possible. A shopper who already knows they enjoy this style has a clearer reason to prioritize it than someone choosing on the word immersive alone. The questionnaire lets you express that difference as a preference or an essential requirement.

The battery compromise follows the mode you want

Bose specifies up to twenty-four hours with Immersive Audio off and eighteen hours with it on. We therefore use the lower figure when your answers say you want to use the feature. Counting the feature’s benefit while keeping the off-mode battery maximum would give a misleading picture.

For a long journey, plan a charging margin around the setting you expect to use. If an advertised forty-hour maximum is essential, this model does not qualify. A strong match on immersive listening should not override a battery requirement that you marked as non-negotiable.

What happens if the battery runs out?

Bose states that the first-generation QuietComfort Ultra must be powered on even when connected by the auxiliary audio cable. Carrying that cable does not solve an empty headphone battery. If you want to keep listening after the headphones run out of charge, consider the documented wired fallback on Sony’s XM5 or Sennheiser’s MOMENTUM 4 instead.

Make the final check personal

Before ordering, think through the place where you will use the headphones most. Consider the duration of a normal session, whether you switch between devices, how often you can recharge and how important the controls feel to you. Specifications help narrow the field, but they do not settle physical comfort or your preference for a particular sound.

We would also inspect the exact offer carefully. Generation, product condition and included accessories can change the purchase you are making even when the headline name looks familiar. Compare equivalent offers rather than treating every Ultra listing as interchangeable.

When another choice is more coherent

The MOMENTUM 4 is the more relevant starting point when the long advertised battery figure is the main attraction. Sony’s XM5 is the confirmed LDAC option in this shortlist. The Bose is most persuasive when its own immersive feature is something you specifically want and the associated charging compromise is acceptable.

If those priorities are equally important, there may be no single decisive choice from the available facts. We would keep the alternatives visible and decide which compromise you can live with, rather than assigning an invented test score to break the tie.

How the alternatives change the decision

MOMENTUM 4 is worth comparing for a longer advertised charging interval. Sony WH-1000XM5 is worth comparing for confirmed LDAC support. Choose between the actual features you will use, while keeping first-generation Bose offers distinct from later models.

A good fit for an easy charging schedule

The MOMENTUM 4 Wireless belongs on the shortlist when frequent charging is the annoyance you most want to reduce. Sennheiser advertises up to sixty hours with noise cancellation on. That puts a clear feature behind the recommendation for the questionnaire’s longer-runtime answer.

We would regard that as room in the charging schedule rather than permission to leave the charger behind indefinitely. Your listening pattern matters. Someone who spends short periods listening each day may value different features from someone who combines commuting, work and evening listening.

Keep the runtime claim in context

The manual qualifies the operating-time figure with its test conditions. Actual use can differ, and the maximum should not be mistaken for a measurement made by this site. Likewise, comparing published maxima from different manufacturers does not reproduce a controlled battery test.

A useful personal calculation is to think through an ordinary week and decide when charging would be convenient. Our recommendation is strongest when a generous advertised maximum solves a repeated inconvenience. It is weaker when you already charge every evening and would gain more from a particular connection feature.

Check codecs before treating them as interchangeable

Sennheiser’s documented codec list does not include LDAC. That matters if LDAC is the specific requirement your phone or player setup is built around: the questionnaire does not count another codec as a substitute. If you did not request LDAC, its absence need not dominate the decision.

Our advice is to avoid comparing codec names as a simple quality ladder. Start with the capabilities of the device you own and the connection you intend to use. A feature that never becomes active is unlikely to improve your everyday experience.

What happens if the battery runs out?

Sennheiser’s manual specifically lists an empty headphone battery as a reason to use the audio cable. This offers a practical backup for a long journey. The supplied cable uses a smaller plug at the headphones and a standard headphone plug at the playback device; check whether your device needs an adapter. This is a listening fallback, not a promise that powered listening features remain available.

Noise cancellation and awareness serve different moments

Adaptive noise cancellation and a transparency mode are included. They offer different ways to manage the sound around you. The existence of these modes does not tell us precisely how natural outside sound will feel or how effectively a particular noise will be reduced.

Think about when you actually want isolation and when you need to hear someone nearby. We would put that routine ahead of broad claims about immersion. Comfort also remains personal, and a long battery specification is useful only if you enjoy wearing the headphones for the sessions you have planned.

The decision against the other candidates

If long intervals between charges are your leading preference, this is a sensible first review to read. Sony’s XM5 becomes more relevant when LDAC is a requirement. Bose’s first-generation Ultra becomes more relevant when its particular immersive mode is the feature you want to explore.

The best decision may therefore change after one answer changes. We would choose MOMENTUM 4 for its documented battery-focused fit, while leaving sound preference and physical comfort to a listening and fit assessment rather than trying to infer them from runtime.

How the alternatives change the decision

Sony’s XM5 supplies the confirmed LDAC option. Bose’s first-generation Ultra supplies Bose Immersive Audio. Neither replaces the long-battery preference automatically; use the importance you gave each answer to decide which compromise makes sense.

Model covered

WH-1000XM5 (Black)

Claimed battery

Up to 30 h AAC / 26 h LDAC, ANC on

Noise cancellation

Active

Listening feature

LDAC support

¹ Battery and charging figures are manufacturer claims under differing conditions. Bose lists up to 24 hours with Immersive Audio off or 18 hours with it on. Weight does not establish comfort.

Start with the feature you will actually use

The WH-1000XM5 is the option to investigate in this shortlist when you want LDAC on a compatible phone or player and an ordinary charging routine is acceptable. It is the XM5 model specifically; a similar-looking offer for a different generation does not share this review automatically.

We would begin by checking the device you listen from. Buying around a codec that your device cannot use puts the emphasis on the wrong feature. If you are unsure about codecs, leave that answer open and let the practical differences guide the shortlist.

LDAC support is a compatibility decision

Sony lists SBC, AAC and LDAC among the supported Bluetooth audio formats. That establishes a capability, not an assurance that every phone will use it or that every listener will prefer the result. Check the source device and available settings.

Our advice is to evaluate the complete listening chain: device, connection settings and the content you play. If LDAC is essential, a confirmed compatible pair is a sensible filter. If it is merely something you have heard mentioned, avoid letting it overshadow comfort, controls and the way you use headphones each day.

Use the battery figure for your settings

Sony’s operating-time guide makes an important distinction: with noise cancellation enabled, its music-playback maximum is thirty hours for AAC and twenty-six hours for LDAC. It also notes that settings and usage can reduce runtime. We use the LDAC figure when you select that feature in the questionnaire.

For planning a trip, leave a margin instead of allocating every advertised hour. A battery maximum can tell you whether a product is worth considering, but it cannot predict a day split between calls, music and different features. Our shortlist does not treat these claims as a controlled endurance test.

What happens if the battery runs out?

Sony confirms that music playback works through the supplied audio cable with the headphones switched off. Noise cancellation needs the headphones to be powered on. For a long journey, that gives you a listening backup when the headphone battery is unavailable. Check that your playback device has a compatible audio output, or bring a suitable adapter.

What specifications cannot decide for you

A feature list cannot establish how the earcups fit your head, whether you enjoy the sound, or how calls work in the places you use them. We have not performed those listening and wear tests. The recommendation therefore concerns documented fit to your answers rather than a promise of the best sound or noise cancellation.

Our practical advice is to identify your least forgiving situation before buying: a long journey, a shared office or an extended call. Look for a way to evaluate that situation, and check the seller’s return terms if fit is uncertain.

How the alternatives change the choice

The MOMENTUM 4 is the charging-focused alternative in this comparison. The first-generation Bose Ultra is the alternative if Bose Immersive Audio is specifically important to you. Those priorities can reasonably point different people to different headphones.

Choose the Sony when the compatibility feature is useful in your own setup. If the questionnaire gives it an equal position with another model, use the compromises to decide rather than reading the display order as an independent sound-quality judgment.

How the alternatives change the decision

MOMENTUM 4 has the longer advertised battery maximum in this shortlist. Bose’s first-generation Ultra provides Bose Immersive Audio, with a lower runtime claim when that feature is enabled. Sony is the confirmed LDAC option among the models currently profiled here.
