Both sound great but take different approaches. The XM6 is warm and bass-forward - enjoyable straight out of the box. LDAC support means you can actually stream hi-res audio wirelessly. The QC Ultra is slightly brighter and more neutral, with Immersive Audio adding spatial depth to stereo tracks. Sony takes it on codec support alone.

Sound Quality
Winner: Sound Quality
Sony WH-1000XM6
Sony - warmer sound and LDAC hi-res audio tips the balance.
Noise Cancellation
Closer than ever. Sony's Auto NC Optimizer adjusts dynamically and handles low-frequency rumble (planes, trains) slightly better. Bose's CustomTune maps your ear geometry for personalized ANC. In an office with irregular noise, the difference is almost imperceptible. On a flight, Sony has a slight edge.
Winner: Noise Cancellation
Sony WH-1000XM6
Sony by a hair, mainly for travel. In offices, it's a tie.
Comfort & Build
This is where Bose pulls away. The QC Ultra's earcups are plush, headband well-padded, and clamp force gentle enough for all-day wear. At 250g, they're lighter too. Sony improved the XM6 headband significantly, but after 6+ hours (especially with glasses), Bose is still noticeably more comfortable.
Winner: Comfort & Build
Bose QuietComfort Ultra
Bose wins. If you wear headphones 8+ hours daily, this matters.
Battery Life
Sony: 30 hours. Bose: 24 hours (18 with Immersive Audio on). Both have quick charge - Sony gives 3 hours of playback from a 3-minute charge. For travelers, Sony's battery handles a transatlantic round trip on a single charge.
Winner: Battery Life
Sony WH-1000XM6
Sony's 30-hour battery outlasts Bose by 6 hours. Meaningful for travel.
Final Verdict
Sony WH-1000XM6 takes it
For most people, the Sony XM6 is the better buy. It matches or beats Bose in ANC, sound, battery, and codec support - for $30 less. The QC Ultra earns its premium if comfort is everything, or if you spend hours on calls daily. Both are excellent. You won't regret either.
Frequently Asked Questions
Meaningful but not huge. ANC is about 15-20% better, the headband is more comfortable, and real-world battery life improved. Worth it from an XM4 or earlier. From the XM5, it's a nice-to-have, not a must.
For casual gaming via Bluetooth, yes. But Bluetooth adds 100-200ms latency - noticeable in competitive games. Use the included 3.5mm cable for zero-latency audio.
Both work with all Bluetooth devices. The XM6 supports LDAC (hi-res on Android) while the QC Ultra doesn't. On iPhone, both use AAC and sound equally good.
