Momentum 5: Premium ANC Headphones With a Practical Twist
The Sennheiser Momentum 5 wireless headphones arrive as a careful evolution of the Momentum 4 rather than a radical redesign, but one change stands out: a user-replaceable battery. Sennheiser keeps its 42mm transducer and a tuning aimed at full-bodied sound with dynamic bass, while adding Hi-Res Audio certification and Snapdragon Sound with support for aptX Lossless in compatible setups. Active noise cancellation has been significantly upgraded, with the number of microphones dedicated to ANC and transparency doubled to four per side, which Sennheiser says makes the system up to three times more effective at cutting background chatter. The Momentum 5 also delivers up to 57 hours of playback with ANC on and can provide about three hours of listening from a five-minute fast charge. In short, these are unmistakably premium ANC headphones—but now with a design that considers their entire lifespan, not just their launch-day performance.
Why a Replaceable Battery in Headphones Is a Big Deal
In the Momentum 5, Sennheiser has shifted from a sealed cell to a 700 mAh battery that owners can swap themselves using only a small Phillips-head screwdriver. That transforms the headphones from a disposable gadget into something closer to a long-term device. Lithium-ion batteries inevitably lose capacity; in sealed designs, that often turns excellent headphones into e-waste once runtimes become unusable. With replaceable battery headphones like the Momentum 5, users can restore endurance instead of paying for factory service or buying a new pair. The change aligns with Sennheiser’s messaging that high-performance sound and environmental responsibility should coexist, supported by more adaptable hardware and compact, plastic-free packaging. It also dovetails with a rising right to repair movement that argues consumers should be able to maintain the products they own, especially expensive electronics whose main failure point is almost always the battery.
Lossless Audio and Head Tracking Meet Long-Term Ownership
Repairability is only one pillar of the Momentum 5’s pitch. The headphones layer in advanced wireless features designed to keep them relevant for years. Snapdragon Sound enables aptX Lossless, delivering CD-quality 16-bit/44.1kHz audio over Bluetooth when paired with compatible Qualcomm-based devices or Sennheiser’s own BTD 700 dongle. Out of the box, the headphones support Bluetooth 5.4 and have been engineered to gain Bluetooth 6.0 via a future firmware update, extending their wireless future-proofing. A day-one firmware update will also unlock Dolby Atmos with head tracking for immersive, positional listening on supported content. Combined with Sennheiser’s Smart Control Plus app—with an 8-band EQ, presets, and sound personalization—the feature stack underscores a new philosophy: sustainable audio gear should not mean compromised performance. Instead, the Momentum 5 aims to be both technically ambitious and structurally maintainable over time.
EPOS and the EU: Battery Swaps Become the New Normal
Sennheiser’s move doesn’t happen in isolation. EPOS, a specialist in enterprise headsets, has announced that all new products will adopt a near-tool-free, paperclip-based battery replacement system. Starting with the IMPACT 500, EPOS designs its headsets so users or IT teams can perform battery swaps in minutes, using only a paperclip or similar object. Crucially, the company is committing to keep original replacement batteries available for at least five years after each model is discontinued. This proactive shift anticipates the EU Battery Regulation 2023/1542, which will require portable batteries in many products to be removable and replaceable by end users from February 18, 2027, using commonly available tools and without damaging the device. EPOS frames its approach as part of a long-standing design philosophy rather than a bare-minimum compliance play—a stance that could pressure competitors in both consumer and business audio to rethink sealed-battery hardware.
From Compliance to Consumer Expectation: The Future of Repairable Audio
Together, Sennheiser’s Momentum 5 and EPOS’s paperclip-standard headsets point to an inflection point in audio hardware. Regulatory pressure around removable batteries is one driver, but growing consumer awareness is just as important. Buyers are increasingly asking how long their premium ANC headphones will last and whether they can perform simple repairs themselves. Replaceable battery headphones directly address concerns about product longevity, ownership rights, and mounting electronic waste. Brands that embrace this shift early can differentiate on more than just sound quality and features; they can credibly claim to support the right to repair and sustainable audio gear. As more manufacturers move toward swappable cells, accessible spare parts, and clear documentation, repairability is likely to become a baseline expectation rather than a niche selling point—much like ANC and wireless connectivity did a decade ago.
