The catch
Beats Studio Pro
The ANC rating tops out at 24 hours.
Side by side
If a flat battery must never end your analog listening, Beats Studio Pro is the one. QuietComfort Ultra 2nd Gen is better for documented two-device multipoint and its 30-hour Quiet-mode rating. USB audio and an inward fold come with both. Bose needs power even when you use its analog cable.
Before you buy
Beats keeps playing on an analog lead alone with a flat battery. Bose needs its electronics powered, though its manual allows external USB power once the battery is depleted. For that fallback with Bose, bring a USB power source along with the audio lead.
Where this comes from
According to Beats documentation, analog playback needs no battery power. Pages 33 to 35 of the Bose Ultra 2 manual require powered-on operation and allow external USB power when the battery is depleted.
The catch
The ANC rating tops out at 24 hours.
The catch
Battery or USB power is needed for analog listening. The audio cable by itself is no backup for a flat battery.

Beats Studio Pro and Bose QuietComfort Ultra 2nd Gen differ on battery-free backup, USB audio and long ANC listening. Work out which connection suits your travel.
If a flat battery must never end your analog listening, Beats Studio Pro is the one. QuietComfort Ultra 2nd Gen is better for documented two-device multipoint and its 30-hour Quiet-mode rating. USB audio and an inward fold come with both. Bose needs power even when you use its analog cable.
Which one fits
Passive analog operation works on Beats. Bose Ultra 2 needs battery or USB power.
With a compatible source and cable, digital USB listening works on both.
Multipoint is documented for Bose. The reviewed Beats record does not establish the same generic behavior.
That mode is rated at 23 hours by Bose. The 24-hour ANC figure for Beats describes a different listening mode and test.
In practice
Beats keeps playing on an analog lead alone with a flat battery. Bose needs its electronics powered, though its manual allows external USB power once the battery is depleted. For that fallback with Bose, bring a USB power source along with the audio lead.
According to Beats documentation, analog playback needs no battery power. Pages 33 to 35 of the Bose Ultra 2 manual require powered-on operation and allow external USB power when the battery is depleted.
The 30-hour figure in Quiet mode drops to 23 hours in Immersive Audio. A 24-hour listening plan falls under the first maximum and over the second. Settle on the mode you will really use before you trust the headline.
30 - 23 = 7 hours. Take 24 hours as an example: it is 6 under the standard Bose rating and 1 over the Immersive Audio rating. Both are manufacturer maximums and not guaranteed endurance.
The USB-audio requirement is met by both. Only Studio Pro also meets the empty-battery analog requirement. A longer standard wireless rating on Bose does not stand in for that fallback when you forget to charge.
The combined requirement is USB audio plus passive analog. Beats has both, while Bose Ultra 2 has USB audio and no passive analog playback.
Plug in your setup
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.
Plays over Bluetooth.
Plays over Bluetooth.
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.

Beats, Studio Pro
This folding over-ear pair can be used three useful ways: over Bluetooth, over digital USB-C, or with a battery-free analog cable. Note that its USB sound profiles are a separate mode from noise-canceling Bluetooth listening.

Bose, QuietComfort Ultra Headphones (2nd Gen)
Ultra 2 beats the original Ultra on USB-C listening and on its longer 30-hour Quiet-mode claim. If analog playback has to keep working with a completely flat battery, pick QuietComfort 2 instead.
Spec by spec
| Spec | Beats Studio Pro | Bose QuietComfort Ultra Headphones (2nd Gen) | In practice |
|---|---|---|---|
| Passive analog without battery or USB power | Supported | Not supported | A passive wired backup is something Beats can do. Bose needs battery or external USB power. |
| Standard ANC playback claim | Up to 24 hours | Up to 30 hours in Quiet or Aware | Setting aside test-condition differences, Bose publishes six more hours. |
| Immersive-mode battery figure | 24 hours is the ANC or Transparency claim | Up to 23 hours with Immersive Audio | Do not plan a full trip in Immersive Audio around the Bose 30-hour claim. |
| Digital USB audio | Supported | Supported | A direct USB-C listening path is available on both with a compatible source. |
| Headphone weight | 260 g | About 264 g | A gap of roughly four grams is thin ground for a verdict on comfort. |
| Two-device multipoint | Generic support not established in the reviewed record | Supported | For a laptop-and-phone routine, the two-device connection is documented by Bose. |
Trade-offs
Change of plan
Go with Beats Studio Pro. Passive analog playback comes with Studio Pro.
Go with Bose QuietComfort Ultra Headphones (2nd Gen). Both two-device multipoint and up to 30 hours in Quiet or Aware are documented by Bose.
Neither model fits. That guarantee is not established by the available claims. Bose advertises 23 hours in Immersive Audio.
Decision guide
A dead battery that cannot be allowed to silence analog playback points to Beats Studio Pro. Documented two-device multipoint and the 30-hour Quiet-mode rating point to QuietComfort Ultra 2nd Gen. Both handle USB audio and fold inward, but Bose still needs power with its analog cable.
Between chances to charge, a longer wireless rating is what helps. After you have already forgotten to charge, passive analog playback is what helps. Bose has more rated Quiet-mode time, and Beats has the cable-only fallback. These are two different advantages and shouldn’t be lumped together.
Planning to keep Bose Immersive Audio on for the whole trip? Then plan around its 23-hour figure. The bigger 30-hour number applies to Quiet or Aware mode. Calls, volume and other settings can shave off more time.
Here, the second-generation Ultra goes up against Studio Pro. USB connections work differently on the original Ultra, and standard QuietComfort models differ in passive playback. Before paying, read the full model name on Amazon and look at the seller, condition and returns for your selected listing.
