Sennheiser Announces Momentum 5: Replaceable Battery and Enhanced ANC

Sennheiser has unveiled its highly anticipated flagship wireless headphones, the Momentum 5 Wireless. This marks a refresh of the series following the Momentum 4, which was released approximately four years ago. While the new model bears a strong resemblance to its predecessor in outward appearance, it boasts significant internal advancements. Most notably, these include a major upgrade to its Active Noise Cancelling (ANC) capabilities and the introduction of a user-replaceable battery—an unusual feature in the headphone industry.

Retained Design and Premium Feel The Momentum

5 carries forward the modern design style introduced with the Momentum 4. The retro aesthetic of earlier models has been set aside in favor of larger ear cups and a sleeker silhouette. While the design may not stand out dramatically compared to competitors, Sennheiser appears to have prioritized comfort and wearability. The headphones are available in three color options: black, white, and denim blue. While the exterior design remains understated, the internal improvements are noteworthy. One of the standout features is the user-replaceable battery. Battery degradation is often the limiting factor in the lifespan of wireless headphones, but with this model, users can replace the battery themselves. This is a reassuring feature for those who wish to use their headphones for an extended period.

Enhanced ANC and Call Quality Sennheiser has

made significant advancements in both noise-canceling and call quality with the Momentum 5. The key to these improvements lies in the doubling of microphones. With four microphones on each earcup, for a total of eight, the headphones can more precisely detect and cancel ambient noise. According to the company, the new ANC technology is up to three times more effective at reducing low-frequency noises, such as the hum of airplane engines or background chatter. This improvement promises to greatly enhance immersion during commutes or travel. Furthermore, the additional microphones also improve call quality, ensuring clearer reception of the user’s voice during hands-free calls.

Lossless Audio and Next-Gen Bluetooth The

Momentum 5 also raises the bar in wireless audio quality. Sennheiser has achieved Hi-Res Audio certification and has added support for the AptX Lossless codec. This enables wireless streaming of CD-quality, 16-bit/44.1kHz lossless audio. However, to fully utilize this feature, a Qualcomm Snapdragon Sound-compatible device—such as smartphones from Sony or Motorola—is required. Devices from Samsung, Google, and Apple do not support AptX Lossless, meaning users of these brands will have to rely on the standard AAC codec. Additionally, the Momentum 5 supports Dolby Atmos and spatial audio with head tracking, delivering an immersive sound experience. It operates on the Bluetooth 5.4 standard, with a planned upgrade to Bluetooth 6.0 via a future firmware update. Although the exact timing of the update has not been disclosed, the promise of compatibility with future standards adds another layer of longevity to the product.

Battery Life and Accessories The Momentum 5

offers a battery life of approximately 57 hours. While this is slightly less than the Momentum 4’s 60-hour runtime, it still significantly outperforms competitors like the Sony WH-1000XM6, which lasts about 30 hours with ANC activated. Combined with the replaceable battery, Sennheiser has clearly designed this model with long-term usage in mind. The carrying case that comes with the headphones has been reduced in size by 20%, making it more portable. The Momentum 5 is priced at $399.99 (just over 60,000 yen), which is $50 more than the Momentum 4’s launch price of $349.99. However, given the enhanced features, the price increase seems justified. The headphones are scheduled for release on June 30, 2026. With the Momentum 5, Sennheiser has reinforced the three pillars of its flagship wireless headphones: “sound quality,” “comfort,” and “long-term usability.” The replaceable battery, in particular, is a significant appeal for environmentally conscious users and those who want their headphones to have a longer lifespan. It remains to be seen how this bold move will be received in the highly competitive high-end wireless headphone market.
