Sennheiser is shipping a screwdriver in the box with its new flagship earbuds. That’s not a gimmick, it’s the entire pitch. The MOMENTUM True Wireless 5 has user-replaceable batteries in both the earbuds and the charging case, something almost nobody in this category bothers to offer. Most premium earbuds are built to be assembled and never opened again, only thrown away. It’s something Apple pioneered, and everyone just accepted. Sennheiser looked at that premise and said “Hold my screwdriver…”
Announced August 20 and landing September 3 for $299.95, the True Wireless 5 arrives in five metallic colorways, graphite, cream, copper, denim, and lavender, with Dolby Atmos head tracking, Bluetooth 6.0, and a redesigned IP54 rated shell. All good upgrades, none of them the real story. The real story is that when the battery eventually degrades, you pop it open and swap it yourself instead of retiring the whole product. Most premium earbuds treat that as impossible. Sennheiser just proved otherwise, screwdriver included.
Designer: Sennheiser
Sennheiser sculpted the new housing using data pulled from thousands of ear scans, chasing a fin-less, “barely there” silhouette that its own testers rated more comfortable than the outgoing MOMENTUM True Wireless 4 by a 73 percent margin. A micro-perforated acoustic mic plate handles wind turbulence so gusts do not wreck call quality or trip up the noise cancellation. The case got the same attention, trading bulk for a narrower, low-friction shape that slides into a pocket instead of fighting it. None of that reads like a company that treated repairability as a compromise. It reads like a company that treated it as a design brief.
Getting inside without wrecking the seal, while still holding an IP54 rating, is genuinely impressive. Sealed adhesive construction has always been the industry’s excuse for why earbuds cannot survive sweat and also be opened by a human being with a screwdriver. Sennheiser just did both at once, and did it on a product this compact, packed with a 7mm TrueResponse driver, an eight sensor call array, and enough silicon to run Dolby Atmos head tracking. The battery swap itself is supposedly a few minute job, not a surgery. That distinction matters more than any spec bump on the sheet, because a spec bump gets outdated in a year and a battery you can replace keeps the product alive for as long as you’re willing to keep unscrewing it.
In July, EU regulators exempted wireless earbuds out of the incoming battery replaceability law entirely, citing water exposure and the risk of a normal person mangling a lithium cell the size of a coin. It was a reasonable enough excuse, and one the industry itself lobbied for. Sennheiser announced a product a few weeks later that quietly makes the excuse look thin. Fairphone got there first with its Fairbuds back in 2024, proving the concept was possible even in a startup’s budget hardware. A flagship brand with an 80 year audio pedigree doing the same thing at premium pricing is a louder statement, and one the rest of the industry will have a harder time waving off as a niche experiment from an ethical hardware outlier.
What happens next is the part nobody has answered yet. A replaceable battery only means something if the replacement itself stays cheap and available for years, the way Fairphone sells its cells for a few dollars with a published guide. Sennheiser hasn’t said what a spare battery will cost or how long it plans to keep selling them, which we’ll wait and watch. The screwdriver is a promise. Whether Sennheiser makes that screwdriver still useful even after 3-4 years is something worth keeping tabs on.
