Sennheiser MOMENTUM 5 adds stronger ANC and a replaceable battery

Sennheiser's MOMENTUM 5 Wireless is now broadly available after its June US release, bringing a series of practical upgrades to the company's premium over-ear line. The fifth-generation model retains the 42mm transducer used by its predecessor, but adds stronger active noise cancellation, spatial-audio support, and hardware designed to remain serviceable for longer.

The most unusual change is a user-replaceable 700 mAh battery. Sennheiser rates the headphones for up to 57 hours per charge with active noise cancellation enabled, and says the cell can be replaced with a small Phillips-head screwdriver. The storage case is also 20 percent smaller, while the retail packaging eliminates plastic.

For wireless playback, MOMENTUM 5 ships with Bluetooth 5.4 and supports Snapdragon Sound with aptX Lossless. Sennheiser says the hardware is ready for a future Bluetooth 6.0 update. Dolby Atmos playback with head tracking is enabled through firmware and requires compatible content and a supported source device. The Smart Control Plus app provides an eight-band equalizer, presets, and personalized sound tuning.

Sennheiser also doubled the number of microphones dedicated to noise cancellation and transparency, using four microphones per side. The company claims the new system is up to three times more effective at reducing ambient voices than the previous generation. A 3.5mm cable and USB-C charging cable are included for wired listening and travel use.

Ear cups and headband

The $399.99 price puts MOMENTUM 5 against established premium wireless headphones rather than studio-only models, but its replaceable battery and lossless-codec support give it a distinct long-term ownership angle. Amazon and B&H carried MOMENTUM 5 Wireless when MusicGearWatch verified US availability on August 11, 2026.
