The catch
Bose QuietComfort Ultra Headphones
Even with the analog cable, the headphones must be switched on.
Side by side
Bose QuietComfort Ultra vs QuietComfort Ultra 2 Compared: Both need cable power, Ultra 2 adds USB audio
Quick verdict
Ultra 2 is the pick for direct USB-C audio or more time between charges. The original Ultra is the pick if Bluetooth and powered analog meet your needs and its exact-model offer is better. Battery-free analog playback is missing from both.
Before you buy
Why, and what it costs you
Two distinct improvements in runtime
The standard rating rises 25% with Ultra 2, and the Immersive Audio rating rises 27.8%.
Where this comes from
25% = (30 − 24) ÷ 24. 27.8% = (23 − 18) ÷ 18.
The catch
Bose QuietComfort Ultra Headphones (2nd Gen)
Unlike the standard QuietComfort models, it cannot play analog audio without power.

What this page compares
Bose QuietComfort Ultra generations side by side on USB audio, standard and Immersive battery claims, weight and the powered-analog limitation that both keep.
Day to day
How each one fits your routine
For wired meetings, the newer model calls for a software check
If your computer requires wired USB calls, Ultra 2 is the model to look into. The firmware it launched with and its current calling capability are different states, so an unopened box does not settle compatibility on its own. Before changing your work setup, confirm the installed version and the meeting app. The original Ultra has no USB audio, which means keeping it also means keeping another approved microphone and audio route for that laptop.
Where this comes from
Bose lists PC USB voice support starting with firmware 8.2.20 and warns that support differs between communication apps. Firmware from September 2026 improves USB calling compatibility, but it carries no universal application guarantee.
Ultra 2 does not become a console headset because of a gaming update
When the job is mixing game sound and voice chat from a PC, the firmware feature documented for Ultra 2 deserves a check against your computer and app. For a gaming console, that feature gives you no reason to choose it. Hold on to the original if your setup already works, or widen the shortlist to a console headset whose audio and microphone route is explicitly supported.
Where this comes from
In Bose’s 10.12.12 release notes, USB game/chat balance is limited to compatible PCs and mobile devices, and gaming consoles are explicitly excluded. No console workaround is documented.

In practice
Differences you will notice
Two distinct improvements in runtime
The standard rating rises 25% with Ultra 2, and the Immersive Audio rating rises 27.8%.
How we worked this out
25% = (30 − 24) ÷ 24. 27.8% = (23 − 18) ÷ 18.
USB comes with the upgrade, passive playback does not
The power requirement for the analog path stays, even with the new digital listening path.
How we worked this out
USB audio works on Ultra 2. Analog audio needs power on both generations.
The added weight comes to about 3.9%
By the rounded published figures, Ultra 2 weighs approximately 10 g more.
How we worked this out
3.9% = (264 − 254) ÷ 254 × 100.
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.
Option A
Bose, QuietComfort Ultra Headphones
QuietComfort Ultra Headphones
This is the folding first-generation Ultra, with CustomTune and head-tracked Immersive Audio. Weigh it against Ultra 2 based on the actual offer, but note that it has no USB audio like the newer model.
- Best for
- Digital USB audio is not something you need.
Facts we checked
- Standard playback claim: Up to 24 hours
- Immersive Audio claim: Up to 18 hours
- USB audio: Not supported
- Playback while charging: Check first-generation operating restrictions
Option B
Bose, QuietComfort Ultra Headphones (2nd Gen)
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.
- Best for
- Listening directly over USB-C is what you want.
Facts we checked
- Standard playback claim: Up to 30 hours
- Immersive Audio claim: Up to 23 hours
- USB audio: Supported
- Playback while charging: Supported
Spec by spec
Where they really differ
| Spec | Bose QuietComfort Ultra Headphones | Bose QuietComfort Ultra Headphones (2nd Gen) | In practice |
|---|---|---|---|
| Standard playback claim | Up to 24 hours | Up to 30 hours | Six rated hours are added by Ultra 2. |
| Immersive Audio claim | Up to 18 hours | Up to 23 hours | In this mode the gain is five hours. |
| USB audio | Not supported | Supported | The newer USB port takes digital sound as well as charge. |
| Playback while charging | Check first-generation operating restrictions | Supported | For listening while plugged into USB power, Ultra 2 is the straightforward pick. |
| Approximate weight | 254 g | 264 g | Around 10 g is added by the new generation. |
| Battery-free analog | No | No | After depletion, a cable by itself will not keep either one playing. |
| Multipoint | Supported with current software | Supported | Before assuming the original Ultra cannot switch between two devices, update it. |
Trade-offs
What each pick costs you
With Bose QuietComfort Ultra Headphones
- This generation cannot carry digital audio over USB-C.
With Bose QuietComfort Ultra Headphones (2nd Gen)
- A separate 23-hour battery claim applies to Immersive Audio.
Decision guide
How to decide
Go with Ultra 2 for direct USB-C audio or longer gaps between charges. Stay with the original Ultra when Bluetooth and powered analog are enough and its exact-model offer is better. Neither lets you play analog without a battery.
Desk use makes the strongest case for upgrading
On the first Ultra, the USB-C socket cannot take audio. Ultra 2 removes that limitation and supports listening while charging. For daily laptop use, that changes your routine more directly than another processing feature you may rarely touch.
Do not compare mismatched Bose modes
A 30-versus-18 comparison mixes Ultra 2’s standard mode with the original’s Immersive Audio mode, which is unfair. Compare 30 against 24 or 23 against 18. Either pairing shows an improvement without overstating it.
The original needs up-to-date software
An update gave the first Ultra multipoint. An old review that calls it single-device only does not describe the current product reliably. Install current firmware before you judge that behavior.
