- Which has better noise cancellation, the Momentum 4 or the QC35 II?
- The Momentum 4. Its adaptive ANC adjusts to your surroundings and is a generation newer than the QC35 II's fixed system. The Bose still cuts engine and cabin noise well, but voices and higher sounds get through more.
- Is the Momentum 4 worth the extra money over the QC35 II?
- Yes for most shoppers. At $199.99 at Best Buy as of November 6, 2026, the Momentum 4 gives you triple the battery life, USB-C, multipoint and better ANC. Only buy the QC35 II if it is significantly cheaper.
- Which is better for long flights?
- The Momentum 4, mainly for battery. 60 hours means you can fly several long trips without charging, against 20 hours for the QC35 II. The Bose is lighter and some people prefer its clamp, so comfort is a personal call.
- Can I use either one wired?
- Yes. The Momentum 4 includes a 3.5mm cable and an airplane adapter. The QC35 II has a detachable 3.5mm cable and works passively with the power off.
- Which is better for calls?
- The Momentum 4. Its four-microphone array and Bluetooth 5.2 handle calls better than the QC35 II's older Bluetooth 4.1 setup. Neither is a dedicated headset, but the Sennheiser is the stronger choice.
- Do either of these work for the gym?
- No. Neither has a water or sweat resistance rating, so sweat and rain are a risk for both. Look for an IPX-rated model instead.
