The Sennheiser Momentum 5 make every other headphone feel disposable

Here’s something nobody selling wireless headphones wants you to think about: every pair has an expiration date. Because Bluetooth headphones run on a battery, they will eventually die. Those lithium-ion cells degrade a little with every charge, and after a few years of daily use, you’re left with a perfectly good pair of headphones that can’t hold a charge long enough to be worth wearing. For most flagships, that’s the end of the road, and you, dear consumer, are expected to go buy a brand-new pair. With the Momentum 5 Wireless, Sennheiser decided it shouldn’t be that way.

The Momentum 5 sells for under $400 and comes with a 700mAh battery that anyone can replace themselves. Remove four Phillips-head screws on the left ear cup, pull the entire speaker assembly out in one piece, and lift the old cell free — a smartphone repair kit and a few minutes is all it takes. No service center, no mailing your headphones across the country, no replacing a $400 product because one small part wore out.

And the cell you’d be swapping is a great one to begin with. The battery is rated for 57 hours of playback with noise canceling on, longer than just about anything else on the market. There’s even an app setting that caps charging at 80% to slow the cell’s aging, so you can stretch its useful life even further.

It’s a pretty damning indictment of the competition. Apple’s AirPods Max, the Bose QuietComfort Ultra, and Sony’s flagship over-ears — none of them let you near the battery. When those cells fade, your choices are a paid repair, if it’s even offered, or buying a new pair entirely. The industry’s standing excuse has always been that a sealed battery is the unavoidable price of a premium, durable, great-sounding headphone. Sennheiser just showed that’s not true. The Momentum 5 is well-built, lasts longer than almost anything out there, and its noise canceling is no longer the tradeoff it used to be on the Momentum 4 Wireless.

None of this was ever a technical limit, and we’ve known that for a while. Fairphone’s Fairbuds XL proved it a couple of years back, with a battery you can swap yourself and a long list of other replaceable parts, from the ear cushions to the drivers. But Fairphone is a small, sustainability-first brand most people have never heard of, and a niche player making a point doesn’t move an industry. Sennheiser is a different story. It’s one of the first big names in audio to build a flagship around a battery you can replace at your kitchen table. That’s what gives me hope this could be a real turning point for wireless audio: when a company this big makes it obvious there’s no good reason for sealed batteries, the rest of the industry runs out of excuses. A three-year shelf life was always a choice, not a constraint — here’s hoping the rest of them finally start making a better one.
