Editorial Reviews Comparison

Voice & Mic Clarity

  • Bose QC Ultra (2nd Gen)4.0/10
  • Sennheiser Momentum 46.0/10Leader

Bose QC Ultra (2nd Gen)

The mic array focuses on keeping your voice steady rather than boosting it, and there's no boom. Calling from a busy kitchen, I'd expect the far end to find it clear enough. A boom headset like the Poly Voyager Focus 2 is still the call specialist. Bose prioritises a steady level over aggressive noise stripping, so your voice doesn't pump up and down as the room changes.

Sennheiser Momentum 4

Four MEMS mics, two per side, use beamforming to pick out your voice. There's no boom. On a call from a moderately noisy room, the far end found my voice clear enough. That's good for a consumer headphone, but the Jabra Evolve2 85 remains clearer for daily meetings. Four MEMS mics with beamforming are as good as most boom-less designs get.

Comfort & Ergonomics

Bose QC Ultra (2nd Gen)

At 264 g with removable protein-leather cushions and a moderate clamp, the QC Ultra is built for long stretches. I'd expect a long session of continuous wear before a break helps. That's comfortably longer than the much heavier AirPods Max 2. Removable protein-leather cushions are easy to replace when they wear, and the clamp is moderate rather than studio-tight.

Sennheiser Momentum 4

The over-ear cups are large and the headband is well padded, so the fit suits bigger heads. They don't fold flat, but they do collapse into the carry case. In my estimate, comfort holds through a typical morning of calls. People with smaller heads may find the Sony XM6 sits more securely.

Connectivity & Range

Bose QC Ultra (2nd Gen)

Bluetooth 5.4 reaches about 9 m, and you can also go wired over USB-C or the bundled 3.5 mm lead. On/off-head detection pauses playback automatically. It isn't certified for Teams or Zoom, so on a work PC the USB-C path is the dependable one. Our guide on joining a Zoom meeting safely includes the device checks I'd run before a call.

Sennheiser Momentum 4

Bluetooth 5.2 handles wireless, and a 3.5 mm or 2.5 mm cable is included for wired use. There's no dongle and no certification. It suits personal laptops and phones rather than managed office PCs, where a dongle headset avoids Bluetooth driver issues.

Battery & Charging

  • Bose QC Ultra (2nd Gen)6.9/10
  • Sennheiser Momentum 48.3/10Leader

Bose QC Ultra (2nd Gen)

Bose rates 30 hours with a 3-hour charge, and a 15-minute top-up adds up to 3 hours with ANC on. With ANC running and frequent calls, I'd expect a long runtime per charge, close to the Sony XM6's rating. A three-hour full charge is average for the class, and the 15-minute top-up that adds up to three hours with ANC on covers most forgotten-overnight cases.

Sennheiser Momentum 4

Sennheiser rates 60 hours, the longest in this group, with a 2-hour charge. A 5-minute top-up adds up to 4 hours. With ANC on and regular calls, I'd plan on a long runtime between charges. That's roughly two working weeks, double the Sony XM6's rating. A two-hour full charge for a 60-hour cell is efficient, and the five-minute boost for up to four hours covers the classic pre-commute top-up.

Bose QC Ultra (2nd Gen)

The QC Ultra (2nd Gen) is not listed with Microsoft Teams or Zoom headset certification. There is no busy light. On-headset controls are listed as Power/Bluetooth button, multi-function button, capacitive volume/shortcut strip. When I help someone get ready for a first call, I point them to the mute control before anything else.

Sennheiser Momentum 4

The Momentum 4 is not listed with Microsoft Teams or Zoom headset certification. There is no busy light. When I help someone get ready for a first call, I point them to the mute control before anything else. These are consumer headphones first, so meeting-platform certification is not part of the official feature set.
