Sennheiser puts a screwdriver-serviceable battery in a $299.95 earbud, at last year's price
The Momentum True Wireless 5 lets owners swap batteries in both the buds and the case. European rules landing in early 2027 are already visible in the industrial design.

What happened
- Both the Momentum True Wireless 5 earbuds and their charging case have user-replaceable batteries accessible using a compact screwdriver instead of having to hack through layers of glue.
- The Momentum True Wireless 5 will be available starting September 3rd for $299.95.
- $299.95 is the same price as the Momentum 4, which The Verge says launched in early 2024.
- Sennheiser and other companies like Fender and Glorious now offer larger over-ear headphones with swappable batteries, but adoption has been slow for earbuds, which are typically assembled using glue to make them as small and light as possible.
- Bang & Olufsen's Beoplay Eleven earbuds launched in late 2024 with replaceable batteries, but users need to send them in so a professional technician can do the swap.

Why it matters
Sennheiser has made the batteries in both the earbuds and the charging case of the Momentum True Wireless 5 user-replaceable, reachable with a compact screwdriver rather than by hacking through layers of glue [1]. The buds go on sale September 3 at $299.95, which The Verge reports is the same price as the outgoing Momentum 4 [2] [3].
The constraint being worked around is physical, not ideological. Earbuds are typically assembled with glue specifically to keep them as small and light as possible, which is why swappable batteries reached larger over-ear headphones from Sennheiser, Fender and Glorious well before they reached in-ears [4]. The partial attempts are instructive: Bang and Olufsen's Beoplay Eleven, launched in late 2024, has replaceable batteries, but the owner has to send the product in for a professional technician to do the swap [5]. Other earbuds allow a battery change in the case only [6]. The Momentum 5 joins Fairphone's Fairbuds as one of the few products where the owner can replace the batteries in the buds themselves [7], a job Sennheiser says takes "mere minutes" [8].
The Verge attributes the broader return of replaceable batteries in part to European sustainability regulations that take effect in early 2027 [9]. That is the part worth noting for anyone shipping hardware: a flagship redesign has absorbed a serviceability requirement roughly a year and a half before it bites, and the bill of materials change has not been passed to the customer as a premium [2] [3] [9].
It also has not cost capacity. Sennheiser quotes up to 12 hours per charge and up to 40 hours with the Qi-compatible case, against 7.5 and 30 hours on the Momentum 4 [10] [11], increases of about 60 percent and 33 percent [12] [13]. Eight minutes on the charger adds an hour of listening [14]. The case is narrower and, per Sennheiser, more pocket-friendly than its predecessor [15], and the buds themselves are slimmer [16], so the fasteners have not obviously been paid for in bulk.
The rest is a normal generational refresh: a 7mm TrueResponse transducer, Bluetooth 6.0, streaming up to 24-bit/96kHz, and an eight-band EQ in the app [17]; a new ear tip and four-microphone array behind a revised adaptive ANC system [18] [19]; Dolby Atmos and spatial audio with head-tracking accelerometers [20] [21]; and a "robust mode" for high-interference environments [22]. Five metallic finishes are offered: lavender, copper, denim, graphite and cream [23]. Sennheiser also says a 73 percent share of testers preferred the new fit to the previous generation, which is a company figure from company testing [24].
What to watch is the supply side, which neither source addresses: what a spare battery costs, how it is ordered, and how many years Sennheiser commits to stocking one. A screwdriver-accessible cell is only a longer product life if the cell is still purchasable in 2031. Watch too whether competitors ship user-serviceable in-ear batteries before the 2027 deadline [9], now that one flagship has done it without moving its price [2] [3].
