Sennheiser Momentum True Wireless 5: headphones that can replace batteries
Sennheiser Momentum True Wireless 5 features replaceable batteries, Bluetooth 6.0 and 40 hours of battery life. Here are their real limits.

Wireless headphones have a defect that is rarely visible at the time of purchase: their tiny batteries are gradually losing their capacity and are often glued inside a case that is almost impossible to open.
Sennheiser offers a more durable solution with Momentum True Wireless 5. Announced on August 20, 2026, these headphones allow their owner to replace the batteries of both earpieces and case with a small screwdriver.
They are now available for pre-order in Canada.
A replaceable battery in each component
Each earpiece contains a rechargeable battery of 72 mAh, while the case uses one of 760 mAh. All three can be replaced with standard tools, according to the [Sennheiser Canadian Fiche] (https://ca.sennheiser-heating.com/collections/momentum-series-headphones/products/momentum-true-wireless-5).
The manufacturer provides a replacement tool in the box, but no additional batteries. He claims that the operation can be carried out at home within minutes.
This design could considerably extend the duration of use of the product. A lithium-ion battery inevitably loses part of its capacity after years of charging. In the majority of compact headphones, replacement requires specialized tools, professional intervention or the destruction of adhesives that keep the case closed.
The Verge emphasizes that the Momentum True Wireless 5 join the Fairphone Fairbuds among the few models whose earphone batteries can be replaced by the user. Some competitors only allow the replacement of the battery case or require a return to the workshop.
Up to 12 hours without noise reduction
Sennheiser announces up to 12 hours of charge listening when the active noise reduction is disabled. The case carries the total autonomy to a maximum of 40 hours.
With the noise reduction activated, the data sheet limits the range to about six hours for headphones. TechRadar reports a total range of up to 25 hours with the case in these conditions.
The full recharge takes about 90 minutes. A fast charging of eight minutes must provide up to one hour of listening. The case accepts USB-C cable and Qi wireless charging.
These results came from the manufacturer and were obtained with a medium volume iPhone. They will need to be checked with different phones, sound levels, codecs and temperatures.
Bluetooth 6.0 and its high resolution
Momentum True Wireless 5 uses 7 mm TrueResponse dynamic transducers. They support SBC, AAC, aptX, aptX Adaptive and aptX Lossless codecs.
Sennheiser announces a transmission of up to 24 bits and 96 kHz, but only with a compatible source and processor. Therefore, the presence of Bluetooth 6.0 or d
An enhanced mode must improve the stability of the connection in places where several wireless devices are active. Headphones also accept multipoint connection and include a low latency mode.
The Dolby Atmos system can create a spatial sound environment that tracks head movements. However, this function depends on the content, service and device used.
Noise reduction and AI-assisted calls
Sennheiser has reviewed the shape of the headphones and their tips to improve acoustic sealing. The system combines adaptive noise reduction, a mode of transparency and an automatic function to limit wind noise.
For calls, the manufacturer describes a total of eight sensors: six microphones and two bone conduction sensors. An artificial intelligence algorithm must isolate the carrier's voice in a noisy environment.
These improvements have not yet been fully tested independently. The actual quality of calls, noise reduction and transparency remains to be confirmed.
Each earphone weighs about 7 g. The IP54 certification applies only to headphones, which are resistant to dust, sweat and splash. The case is not advertised as water resistant.
Prices and availability in Canada
Momentum True Wireless 5 is available for pre-order at a price of C$ $449.95 in Sennheiser's Canadian boutique. The five colours — graphite, cream, copper, denim and lavender — are displayed at the same price.
The expedition is scheduled to begin on September 3, 2026. The price may vary depending on the retailer, promotion, taxes, colour, region and conditions of sale.
The manufacturer has not yet reported the Canadian price of replacement batteries or their availability date. The repairability of the product will therefore also depend on Sennheiser's ability to offer these parts for several years.
Limits or Considerations
Earphones cost $20 more than Momentum True Wireless 4 in the Canadian store, before any promotion.
No definitive independent test can yet compare their sound, comfort, calls or noise reduction to the high-end models of Bose, Sony and Apple.
The procedure for replacing batteries should also be examined. It will be necessary to check the availability of the cells, their price, the precautions of sealing and the possible consequences on the guarantee.
Finally, battery replacement improves the potential lifetime, but does not automatically make other components repairable. A faulty microphone, charging circuit or transducer could always require professional intervention.
Conclusion
The Momentum True Wireless 5 do not reinvent wireless listening, but they correct one of its main defects: an expensive product should not become unusable simply because its battery has aged.
Their real value will depend on sound quality and noise reduction, but also on the price and long-term availability of replacement cells.
If Sennheiser adequately supports this system, these headphones could help to make the replacement batteries normal rather than exceptional in compact audio devices.
