Bose QuietComfort Ultra Headphones vs Sennheiser Momentum 4 Wireless

Bose QuietComfort Ultra Headphones

Bose reclaims the ANC crown with the best noise cancellation available in consumer headphones.

• The ANC is the best I've experienced — airplane cabin noise, office chatter, and street sounds are effectively eliminated.
• Bose edges out Sony by a slim margin in ANC performance, particularly with low-frequency rumble.

Sennheiser Momentum 4 Wireless

Adequate for office and light commuting, but falls short for frequent flyers.

• ANC is fine for office use but it's clearly a tier below Bose and Sony — you'll hear more airplane noise with these.
• The transparency mode is decent but doesn't match the natural quality of Apple or Bose's implementations.

Rich, warm sound signature that most listeners will enjoy, though audiophiles may want more neutrality.
