Which has better noise cancellation?

The Bose QuietComfort Ultra 2nd Gen. Bose's ANC is the benchmark in over-ear headphones, and the Momentum 4, while effective, sits a step behind it on planes and trains.

Which lasts longer on a charge?

The Sennheiser Momentum 4, by a wide margin. It is rated up to 60 hours with ANC on versus up to 30 hours for the Bose, or about 23 with Immersive Audio.

Is the Bose worth the extra $25?

Only if ANC and spatial audio are your priorities. At $225.00 at eBay versus $199.99 at Amazon as of November 7, 2026, the gap is small, but the Momentum 4 gives you far more battery for less money.

Which is better for long flights?

The Bose cancels engine noise better, but the Momentum 4 lasts longer and includes a flight adapter in the box. For a long trip without charging, the Sennheiser is the safer pick.

Can I use either with a cable?

Yes. Both have a 3.5 mm input and a USB-C port, and both ship with a cable, so you can listen wired when the battery runs out.

Which is better for calls?

Both use beamforming microphones and support voice assistants. The Bose has physical call buttons; the Momentum 4 relies on touch controls. Neither is a dedicated headset.
