For Sennheiser over-ear wireless headphones, shortlist the MOMENTUM 4 Wireless and ACCENTUM Plus Wireless. The published specifications point to a longer stated battery-life claim for MOMENTUM 4, while ACCENTUM Plus documents adaptive noise cancellation and several travel-friendly conveniences. These are manufacturer specifications and guidance—not independent head-to-head tests of sound, comfort, or noise cancellation.
How the two Sennheiser headphones compare
| Factor | MOMENTUM 4 Wireless | ACCENTUM Plus Wireless |
|---|---|---|
| Battery claim with ANC | Sennheiser’s instruction manual states up to 60 hours of Bluetooth music playback with ANC activated. The cited manual section does not specify the test conditions. | Sennheiser lists up to 50 hours via Bluetooth with ANC, measured using an iPhone at medium volume. This specification was updated 2026-08-08. |
| Noise cancellation | The manual documents ANC, but the cited evidence does not directly compare its mode or effectiveness with ACCENTUM Plus. | Sennheiser lists hybrid adaptive ANC. Sonova’s comparison also identifies adaptive ANC as a Plus distinction from standard ACCENTUM Wireless. |
| Controls and automation | The cited evidence does not establish a direct controls comparison with ACCENTUM Plus. | Sonova’s comparison identifies touch controls, proximity sensors with Smart Pause, and automatic anti-wind mode as Plus distinctions from standard ACCENTUM Wireless. |
| Bluetooth and codecs | The cited manual identifies Bluetooth operation, but the evidence here does not establish a comparable codec list. | Sennheiser lists Bluetooth 5.2 and SBC, AAC, aptX, and aptX Adaptive support. Codec support alone does not establish that one headphone will sound better with your device. |
| Weight and design | The manual identifies model M4AEBT as an around-ear, closed-back Bluetooth headphone with 42 mm transducers. Comparable weight is not stated in the cited evidence. | Sennheiser lists a product weight of 227 g and Smart Control app support. |
| Case and cables | The cited evidence does not establish the included accessories for the MOMENTUM 4 package in your region. | The regional product listing names a USB-C cable, carry case, auxiliary cable, quick guide, and manual in the box. |

Which model fits your priorities?
Choose MOMENTUM 4 if the stated battery figure is a priority
The manual’s up-to-60-hour Bluetooth playback claim with ANC is the larger stated figure in this comparison. It is not a controlled comparison with ACCENTUM Plus: the cited MOMENTUM 4 manual section does not provide the same iPhone and medium-volume conditions as the ACCENTUM Plus specification. Actual runtime may vary, so do not treat the difference as a guaranteed advantage for every listener.
The manual also identifies around-ear, closed-back construction and 42 mm transducers. Those are product details, not evidence of a tested sound or comfort advantage.

Choose ACCENTUM Plus if adaptive features and travel accessories matter
Its documented adaptive ANC, touch controls, Smart Pause proximity sensors, automatic anti-wind mode, and included carry case may suit someone who moves between environments and wants more automatic handling. Sonova Consumer Hearing’s comparison article, published 2026-04-23, says: “If your daily routine involves moving through different sound environments, frequent travel, or if you prefer headphones that adjust automatically without requiring manual setup, the Plus offers benefits you are likely to notice in everyday use.” That is the manufacturer’s guidance, not an independent test result.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is the ACCENTUM Plus Wireless worth paying more for?
It may be worth paying extra if you will use its documented adaptive ANC and automation, want the listed carry case and cables, or need its stated codec compatibility for your device. If those distinctions do not matter to you, the available evidence does not establish that the Plus is a better-value choice for sound, comfort, or ANC effectiveness. Compare the current prices for your region rather than assuming the Plus premium is justified for every buyer.
Rank #2
- Audiophile tuning: Sennheiser’s in-house 42 mm transducer and refined acoustic design deliver a neutral audiophile sound with lifelike mids, stunning detail, and a wide, natural soundstage. With minimal digital processing ensuring pure fidelity true to the original recording.
- Wireless or wired: Enjoy high-resolution wireless sound with support for aptX HD and aptX Adaptive, especially when paired with the included BTD 700 Bluetooth adapter. For maximum purity, connect via USB-C for lossless listening up to 24-bit/96 kHz.
- 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.
For context, Sonova’s comparison presents standard ACCENTUM Wireless as suited to more stable listening environments and the Plus as useful when moving between environments. That comparison concerns the standard ACCENTUM and its Plus version; it does not establish a direct performance ranking between ACCENTUM Plus and MOMENTUM 4.
