Choose the Sony WH-1000XM6 if noise cancellation and broad overall performance matter most. RTINGS’ direct comparison says the Sony outperforms the MOMENTUM 4 in most areas it evaluates. Choose the Sennheiser if its stated battery life or aptX-family codec support better fits your priorities and devices. Neither is the right choice for everyone: sound preference, fit, comfort and your local price still matter.
Which model is better for your priorities?
| Your priority | What the available evidence says | Practical takeaway |
|---|---|---|
| Noise cancellation and broad performance | RTINGS’ direct comparison summary favors the Sony in most evaluated areas. What Hi-Fi? also positions the XM6 favorably in its current wireless-headphone guide. | The stronger evidence-led pick is the WH-1000XM6, especially if ANC is your top concern. |
| Battery life | Sennheiser claims up to 60 hours of Bluetooth playback with ANC enabled, under its stated iPhone-at-mid-volume test condition. A comparable Sony battery figure was not established here. | The MOMENTUM 4 has a compelling manufacturer claim, but the available information does not support a numerical battery-life head-to-head. |
| Bluetooth codecs | Sennheiser lists SBC, AAC, aptX and aptX Adaptive for the MOMENTUM 4. A Sony codec list was not verified from readable official specifications. | Consider the Sennheiser if your source device supports the aptX codec you want; codec support on the headphones alone is not enough. |
| Sound and comfort | RTINGS evaluates both categories, but its usable comparison details do not establish a specific sound or comfort winner here. | Fit and listening preference are personal. If possible, try both or buy from a seller with a return policy that suits you. |
| Price and availability | Current comparable prices and local stock were not verified. | Compare live offers in your market before deciding; there is no substantiated price-based winner here. |
Why the Sony is the safer ANC-first choice
The most useful direct comparison evidence favors the WH-1000XM6 across most of RTINGS’ evaluated categories, which include sound, fit and comfort, controls, portability, isolation, microphone, battery, app support and connectivity. That broad result supports recommending Sony to buyers who want a strong all-rounder, particularly when noise cancellation leads their checklist.

This is a source-based recommendation, not a claim of personal testing. RTINGS’ comparison summary is available, but detailed test values are not fully visible in the page text reviewed. What Hi-Fi?’s current buying guide provides additional favorable context for the XM6, but it is not a complete side-by-side specification sheet.
What the MOMENTUM 4 offers on battery and codecs
Sennheiser’s current specifications state: “Up to 60 hrs music playtime via Bluetooth and with ANC (test condition: iPhone, mid volume level).” Treat that as a manufacturer claim under a stated condition, not as an independently measured result or a guarantee of runtime for every listener. The same specifications list SBC, AAC, aptX and aptX Adaptive. To use an aptX-family codec, the phone, computer or other audio source must support it too.
#1 Best Overall
- Hybrid Active Noise Cancelling: 2 internal and 2 external mics work in tandem to detect external noise and effectively reduce up to 90% of it, no matter in trains or offices.
- Immerse Yourself in Detailed Audio: The noise cancelling headphones have oversized 40mm dynamic drivers that produce detailed sound and thumping beats with BassUp technology for your every travel, commuting and gaming. Compatible with Hi-Res certified audio via the AUX cable for more detail.
- 40-Hour Long Battery Life and Fast Charging: With 40 hours of battery life with ANC on and 60 hours in normal mode, you can commute in peace with your Bluetooth headphones without thinking about recharging. Fast charge for 5 mins to get an extra 4 hours of music listening for daily users.
- Dual-Connections: Connect to two devices simultaneously with Bluetooth 5.0 and instantly switch between them. Whether you're working on your laptop, or need to take a phone call, audio from your Bluetooth headphones will automatically play from the device you need to hear from.
- App for EQ Customization: Download the soundcore app to tailor your sound using the customizable EQ, with 22 presets, or adjust it yourself. You can also switch between 3 modes: ANC, Normal, and Transparency, and relax with white noise.
Sennheiser specifies 42 mm dynamic transducers and hybrid adaptive ANC for the MOMENTUM 4. Those are product specifications; on their own, they do not demonstrate that it sounds better or cancels more noise than the Sony.
How to interpret the charging claims
Sennheiser’s specifications page says five minutes of charging can provide up to four hours of playtime. Its US product page separately promotes six hours of listening from a ten-minute charge. These are different claims from different official pages; do not combine them or assume they describe identical conditions. The specifications page also gives an approximate two-hour time to full charge.
Rank #2
- Block the World, Keep the Music: Four built-in mics work together to filter out background noise — whether you're in a packed office, on a crowded commute, or moving through a busy street — so every beat comes through clean and clear. (Not available in AUX-in mode.)
- Two Ways to Hear More: BassUp technology delivers deep, punchy bass and crisp highs in wireless mode — then step it up further by plugging in the included AUX cable to unlock Hi‑Res certified audio for studio-level clarity.
- 40 Hours. 5-Minute Top-Up: With ANC on, a single charge keeps you listening through days of commutes and long-haul flights. Running low? Just 5 minutes plugged in gives you 4 more hours — so you're never stuck waiting.
- Two Devices, Zero Hassle: Stay connected to your laptop and phone at the same time. Audio switches automatically to whichever device needs you — so a call never interrupts your flow, and getting back to your playlist is just as easy. Designed for commuters and remote workers who move smoothly between work and personal listening throughout the day.
- Your Sound, Your Rules: The soundcore app puts everything at your fingertips — dials your ideal EQ with presets or build your own, flip between ANC, Normal, and Transparency modes on the fly, or wind down with built-in white noise. One app, total control.
Check these points before you buy
- Make ANC your deciding factor? The available direct-comparison summary points to the WH-1000XM6.
- Need a particular codec? Check your source device’s supported Bluetooth codecs as well as the headphone specifications.
- Fit and sound matter most? Try the models if you can, or check the retailer’s return terms; the evidence available here does not settle individual preference.
- Comparing value? Check current prices and availability in your market. The older Sony WH-1000XM5 may also be discounted, according to What Hi-Fi?’s current guide, but no current price comparison is established here.
One model comparison, not the whole Sennheiser lineup
This comparison is specifically between the MOMENTUM 4 Wireless and Sony WH-1000XM6. Sennheiser’s MOMENTUM 5 has entered the company’s current lineup, so the MOMENTUM 4 should not be described as Sennheiser’s newest model.
