Choose the Sennheiser MOMENTUM 5 Wireless if you value its longer claimed battery life, replaceable battery, or Sennheiser’s sound and codec profile. Neither model is the clear winner for everyone, and current local prices should decide whether one is the better buy for you.
How the two headphones compare
| Buying factor | Sennheiser MOMENTUM 5 Wireless | Sony WH-1000XM6 |
|---|---|---|
| Noise cancellation | Sennheiser says it reduces distracting voice chatter by up to three times more effectively than the MOMENTUM 4 across midrange frequencies. That is a Sennheiser generational comparison, not a comparison with Sony. | Sony specifies its QN3 noise-canceling processor and adaptive 12-microphone system. What Hi-Fi?’s direct comparison judges its ANC better than the MOMENTUM 5. |
| Battery life | Up to 57 hours, according to Sennheiser. The battery is replaceable. | Up to 30 hours with noise canceling on, according to Sony. |
| Wireless codecs | Bluetooth 5.4; What Hi-Fi? lists SBC, AAC, aptX, aptX HD, aptX Lossless and aptX Adaptive. | Bluetooth 5.3; What Hi-Fi? lists SBC, AAC, LDAC and LC3. |
| Sound | What Hi-Fi? describes a rich, detailed presentation, smooth balance and strong midrange. | What Hi-Fi? describes a more dynamic and engaging presentation. |
| Weight | 290 g, according to What Hi-Fi?. | 254 g, according to What Hi-Fi?. |
| Price evidence | A current same-market price is not established here; check a local retailer. | Sony UK announced launch suggested retail prices of £400 in the UK and €450 in Europe in May 2025. These are historical launch prices, not current prices. |
Battery figures come from each manufacturer under its own stated conditions, so they are not a controlled head-to-head runtime test. Actual performance varies with settings and use. Weight and codec lists are reported by What Hi-Fi?’s comparison; a codec only helps if your playback device and listening setup support it.

Which one has better noise cancellation?
The available direct comparison favors the Sony WH-1000XM6 for ANC. Sony says its QN3 processor is seven times faster than the QN1 processor in the older WH-1000XM5; that is Sony’s comparison of its own processors, not a measurement against Sennheiser. The adaptive 12-microphone system is also a Sony specification.
Sennheiser says the MOMENTUM 5 reduces distracting voice chatter across midrange frequencies by up to three times more effectively than the MOMENTUM 4. That claim is useful as a generational comparison within Sennheiser’s range, but it does not establish how the MOMENTUM 5 compares with the WH-1000XM6. If blocking surrounding noise is the deciding factor between these two, the independent reviewer’s head-to-head judgment points to Sony.

Which has longer battery life, and can you replace the battery?
Sennheiser claims up to 57 hours for the MOMENTUM 5, compared with Sony’s claim of up to 30 hours for the WH-1000XM6 with noise canceling on. Because these are separate manufacturer figures with different test conditions, the gap should not be treated as a measured difference in real-world use. Still, Sennheiser’s stated maximum is substantially longer.
Sennheiser identifies a replaceable battery as a MOMENTUM 5 feature. Sony’s cited product page does not establish a comparable user-replaceable battery claim. If replaceability is important for long-term ownership, that documented feature favors the Sennheiser.

How do they sound, and which devices support their codecs?
What Hi-Fi? characterizes the MOMENTUM 5 as smooth and detailed, with a strong midrange, and the Sony as more dynamic and engaging. Those are the reviewer’s listening judgments, not objective measurements or a guarantee that one sound will suit every listener. If you can, compare them with music you know and the ear pads adjusted as you would wear them.

Codec names alone do not determine sound quality. Your phone, computer, operating system and chosen playback configuration must support the codec for it to be used; otherwise playback falls back to another supported option.
Rank #3

- Parametric EQ: Expert-level equalization lets you define frequency bands, widths, and filters to precisely shape your sound. Tailor bass, enhance vocals, or fine-tune for any genre, just like a mastering engineer.
- Adaptive ANC & Transparency Mode: Powerful noise cancellation blocks distractions without degrading clarity, dynamics, or balance. Transparency Mode instantly lets in surrounding sounds when you need to stay aware.
- Listen for days, not hours: A class-leading 60-hour battery keeps you going through long trips or work weeks. Just 10 minutes of fast charging adds up to 7 hours of playtime, ideal for when you’re on the move.
What about weight and comfort?
What Hi-Fi? lists the Sony at 254 g and the Sennheiser at 290 g. The Sony is lighter on those reported specifications, which may matter during long listening sessions. Weight alone cannot settle comfort: fit, headband pressure, ear-pad shape and individual preference also matter, and the available comparison does not establish that either model will fit everyone better.

Sony UK announced a suggested retail price of £400 for the WH-1000XM6 in the UK and €450 in Europe at launch in May 2025. Those figures are tied to that launch announcement, not a current street price. A current same-market MOMENTUM 5 price is not established here, so there is no sound basis for declaring either one the better value at today’s prices.
