Sennheiser's $400 Headphones Last for Days Without Charging

Sennheiser's Momentum 5 headphones have passed their most detailed independent test so far. TechCrunch reviewed sound, noise blocking, comfort and battery life on September 27, 2026, and judged them to have great sound, excellent battery life and few compromises. TechCrunch

They cost $399.99 in the US. They build on the design of Sennheiser's HD 600 wired headphones and support Bluetooth 5.4, aptX, Snapdragon Sound, Dolby Atmos, lossless high-quality audio, and spatial audio that follows head movement. Sennheiser The Guardian

Those wireless terms affect sound without a cable. Bluetooth 5.4 sends the audio, aptX and Snapdragon Sound keep more detail on phones that support them, and Dolby Atmos places sounds around you. Lossless audio still depends on the song, the phone settings and the wireless signal, but the list matches other top-priced headphones.

The biggest change is noise blocking. The Momentum 5 uses eight microphones to cancel noise, double the last model. Sennheiser says it blocks voices and nearby talk up to three times better than the last model. Call quality and the mode that lets outside sound in will matter in daily use, but more microphones give the system more to work with.

Battery figures were central to the review. They play up to 57 hours with noise blocking on. Ten minutes of charging gives up to seven hours of play. A full charge takes about two hours. The battery can be replaced by the owner.

Settings are in the Smart Control Plus app. It has eight sliders to adjust tone, a control for noise-blocking strength with a wind mode, and a short hearing test that sets sound for you. It works a bit like an eye test, but for ears.

The broader context here is steady progress, not a new invention. The Guardian also called the sound fantastic in July, which matches the September verdict. No single feature is new alone. Other premium headphones already offer multi-microphone blocking, long battery, immersive sound and personal tuning in different mixes.

In my view, the mix is what counts. Long life plus a replaceable battery fixes the normal reason costly wireless headphones wear out, which is an aging battery, not broken speakers. For travelers and work users, 57 hours with noise blocking on means charging weekly, not daily, and ten minutes can cover a workday.

In practical terms, upkeep gets simpler. If the sound stays steady after software updates and the voice blocking works in busy offices, these suit people on many calls, long listening sessions, and trips with fewer chargers to carry.
