Sennheiser Puts User-Replaceable Batteries in Both the Earbuds and the Case: the $299.95 MOMENTUM True Wireless 5 Ships 3 September

Sennheiser has announced the MOMENTUM True Wireless 5, a flagship noise-cancelling earbud whose headline feature is not a codec or a chip but a screwdriver-friendly one: the batteries inside both earbuds and the charging case are user-replaceable. The earbuds are priced at US$299.95 and are set to ship 3 September 2026 from sennheiser-hearing.com and select retailers.

Sealed, disposable lithium cells have been the default in true-wireless earbuds since the category began, with battery degradation typically marking the end of a pair's usable life regardless of how the rest of the hardware holds up. Sennheiser's move to make that specific component serviceable — in both the earbuds themselves and the case that charges them — is the news here, and it lands as replaceable batteries have begun to appear elsewhere in the wider headphone category as well.

What's replaceable, and how big

Sennheiser specifies 72mAh per earbud and 760mAh in the charging case, with all three cells designed to be swapped by the user rather than requiring a factory service. The notes accompanying this announcement don't detail the mechanics of that process — no tools, torque specs, or replacement-cell pricing have been disclosed — so it's not yet clear how involved a battery swap will be in practice.

It's worth being precise about which Sennheiser product this refers to. The MOMENTUM True Wireless 5 is an in-ear earbud. It is a separate product from the Momentum 5 Wireless, an over-ear headphone that launched earlier in 2026 at a different price point and which also introduced a replaceable battery for its category. The two share a naming convention and a serviceability idea, but they are not the same hardware, and specs for one should not be read across to the other.

Connectivity and codecs

The earbuds move up to Bluetooth 6.0 and support SBC, AAC, aptX, and aptX Adaptive/Lossless, giving them a broad codec spread that should cover both lossy Bluetooth defaults and higher-resolution wireless playback where a paired source supports it. Sennheiser has also added Dolby Atmos support with head tracking, aimed at spatial audio content that uses Dolby's format.

Noise cancellation and battery life

Sennheiser describes a revised adaptive hybrid ANC system on the MOMENTUM True Wireless 5, built around an improved microphone array and AI-based voice isolation intended to help calls and voice pickup in noisy environments. None of the notes behind this announcement include independent testing of that ANC system, so how it performs in practice — versus Sennheiser's own description of it — isn't yet established.

On battery life, Sennheiser quotes up to 12 hours per charge with ANC switched off, dropping to 6 hours with ANC engaged, and a total of 40 hours when the charging case is factored in. Those are Sennheiser's stated figures rather than independently verified runtimes.

Design details reported ahead of launch

Ahead of Sennheiser's official announcement, a pre-launch leak report from Basic Tutorials described some design changes for the new earbuds: the fabric cover previously used on the charging case has reportedly been dropped, and the stabilising wings on the earbuds themselves have reportedly been removed. The same report listed four colour options — Graphite, Creme, Copper and Denim. These design and colour details come from pre-launch leak coverage rather than from Sennheiser's own specification sheet, and should be read with that caveat.

That same leak report also quoted a price of roughly EUR300 and a 19 August 2026 launch date ahead of the official announcement. Sennheiser's confirmed figures — US$299.95 and a 3 September 2026 ship date — supersede those pre-launch numbers, and the earlier euro price and launch date shouldn't be treated as confirmed.

What isn't confirmed yet

A few things are notably absent from the sourcing behind this announcement. There's no IP water- or dust-resistance rating listed, no detail on driver size or driver technology, and no indication of how replacement batteries would be sourced or what they might cost. Sound quality, ANC effectiveness, and call performance also remain unassessed, since no outlet in this round of coverage has had hands-on time with a review unit. And while replaceable batteries in true-wireless earbuds are the story, nothing in the available sourcing establishes that the MOMENTUM True Wireless 5 is the first or only earbud in its category to offer one — only that Sennheiser is now doing it at the flagship level, alongside a broader pattern of replaceable batteries showing up across headphones generally.

Pricing and availability confirmed here apply to the US market only; no figures for other regions were part of the official specification coverage.

Yes. Sennheiser has made the batteries in both the earbuds and the charging case user-replaceable, with cell capacities of 72mAh per earbud and 760mAh in the case. Details on the replacement process itself, such as tools needed or where replacement cells would be sourced, have not been disclosed.

Which Bluetooth codecs does the MOMENTUM True Wireless 5 support?
