Sennheiser Momentum 5 and Bose QuietComfort Ultra 2 Headphones Compared

The Sennheiser Momentum 5 and Bose QuietComfort Ultra 2 are premium active‑noise‑cancelling over‑ear headphones launched in 2024. Both use USB‑C and a 3.5 mm jack and support Bluetooth SBC, AAC and aptX Adaptive; the Momentum 5 adds aptX HD and aptX Lossless, while Bose limits its codec range to aptX Adaptive.

Battery life differs markedly: Momentum 5 advertises up to 57 hours with ANC on and a user‑replaceable cell, whereas the QuietComfort Ultra 2 offers about 30 hours on a non‑replaceable battery and employs Bluetooth Low Energy power‑saving. Prices are roughly €400 (≈$430) for the Momentum 5 and $449 (≈€380) for the Bose model. Both provide spatial‑audio features—Dolby Atmos on the Sennheiser and Bose Immersive Audio on the Bose—and companion apps that allow EQ tweaking and multiple ANC modes.

Reviewers note that Bose retains strong ANC performance, especially on low‑frequency cabin noise, while Sennheiser emphasizes longer runtime and broader codec support. Design-wise, the Momentum 5 is non‑foldable, whereas the Bose headset folds for portability. Choice between the two hinges on battery endurance, codec compatibility, price and preferred app functionality.
