This comparison is specifically between the Sony WH-1000XM5 and the original, first-generation Bose QuietComfort Ultra Headphones. It does not describe the Bose QC Ultra 2nd Gen. That distinction matters because Bose added USB-C audio and longer rated battery life to the second generation.
BetterPickAdvisor did not perform a controlled ANC, microphone, frequency-response, or comfort test on these headphones. We separate manufacturer specifications from independent comparative findings and personal-fit judgments.
Short answer by use case
| If you care most about | Better starting point | Reason | Check before buying |
|---|---|---|---|
| Longer rated battery | Sony XM5 | Sony states up to 30 hours with noise cancelling on | Real runtime changes with volume, codec, calls, and settings |
| Compact travel storage | Bose QC Ultra | Bose folds inward into its case | The Bose must remain powered for analog playback |
| Android high-bitrate codec | Sony XM5 or Bose | Sony offers LDAC; Bose offers aptX Adaptive on compatible devices | Your phone must support the same codec |
| Passive wired listening | Sony XM5 | Sony supports playback over 3.5 mm while powered off | ANC and processing require power |
| Comfort and isolation evidence | Bose QC Ultra | RTINGS currently gives Bose a small edge | Clamp, seal, glasses, and head shape can reverse a comfort decision |
| Lowest current price | Neither by default | Both have successors and frequent price changes | Compare final price and return policy on the day you buy |
Evidence snapshot
- Sony’s official WH-1000XM5 specifications support the 30-hour NC-on claim, LDAC/AAC/SBC codecs, 3.5 mm input, and approximately 8.82 oz weight.
- Bose’s original QC Ultra announcement supports the foldable design, up-to-24-hour rating, Immersive Audio, and the original charging-port description.
- Bose’s first-generation product FAQ explicitly says the original QC Ultra does not support USB audio and must be powered on for analog listening.
- Bose’s 2nd Gen announcement identifies USB-C audio and the 30-hour rating as second-generation changes.
- RTINGS’ current side-by-side comparison gives the Bose a small comfort and isolation advantage while noting Sony’s passive wired playback and LDAC support. That is one independent methodology, not a universal result.
Noise cancellation: do not declare a universal winner
The previous version of this page called Sony the ANC winner without a controlled test source. That conclusion was too strong.
RTINGS’ current comparison gives the original Bose QC Ultra a slight noise-isolation advantage, while still describing both products as suitable for noisy environments. Other results can differ because test fixtures, firmware, fit, glasses, hair, and the shape of the listener’s head affect the seal.
The useful buying conclusion is narrower: if maximum ANC is your main reason for buying, try both under a return policy or compare measurement sets that use the same fixture and methodology. Do not compare a manufacturer’s microphone count with another brand’s ANC result; microphone count alone does not measure attenuation.
Sound and codecs
Sony supports SBC, AAC, and LDAC. Bose supports SBC, AAC, and aptX Adaptive on compatible Snapdragon Sound devices. A codec label does not guarantee better sound by itself. The source device, app settings, connection stability, tuning, fit, and recording quality all matter.
The Sony app provides extensive controls for EQ, adaptive sound behavior, and Sony ecosystem features. Bose centers its experience on CustomTune, listening modes, and Immersive Audio. Choose the ecosystem you will actually configure rather than treating spatial-audio branding as a reason to buy on its own.
Calls: evidence is condition-dependent
The old page said Sony was clearly superior in every noisy environment. Independent comparisons do not justify that universal statement. Microphone recording quality and background-noise handling are separate tests, and Bluetooth call performance can change by phone and application.
If calls decide the purchase, listen to microphone samples recorded under the same conditions. Prioritize the environment that matches your use: quiet office speech, wind, steady transport noise, or unpredictable voices.
Comfort and travel
Both headphones are in roughly the same weight class, so the number on the scale does not settle comfort. Cushion depth, headband pressure, clamp, heat, glasses, and ear shape matter more during a long session.
Bose has the clearer travel advantage because the headband folds into the case. Sony’s earcups swivel flat, but the headband does not collapse inward. This is easy to verify and more useful than vague claims about one case feeling “premium.”
Battery and wired use
Sony rates the XM5 for up to 30 hours with noise cancelling on. Bose rates the original QC Ultra for up to 24 hours with Immersive Audio off and up to 18 hours with it on. These are manufacturer maxima under controlled conditions, not guaranteed travel runtimes.
The wired difference is more important than it first appears:
- Sony can play through its 3.5 mm input while powered off. Turning it on enables its processing and ANC.
- The original Bose uses a 2.5-to-3.5 mm cable and must be powered on even for analog listening.
- Neither model in this comparison accepts audio over USB-C. USB-C audio belongs to the Bose 2nd Gen, not the original Bose shown here.
When to skip both
Skip both if the discount is small relative to the Sony WH-1000XM6 or Bose QC Ultra 2nd Gen. Also skip both if you need certified workplace hearing protection: consumer ANC headphones should not replace equipment with an appropriate Noise Reduction Rating.

Research notes
Specifications and generation differences were checked on August 19, 2026. Retail prices were deliberately removed because they change frequently. The page retains its original URL because the product-pair search intent is unchanged; the content now identifies the exact Bose generation instead of mixing first- and second-generation features.
