Frequently Asked Questions (Lab Verified)
Which headphone has superior noise cancellation?
In low-frequency airplane engine rumble, both are nearly identical. In mid-frequency human speech and coffee shop chatter, the Bose QuietComfort Ultra edges ahead by roughly 3dB to 4dB.
Can you fold either headphone for compact travel?
The Bose QuietComfort Ultra folds inward into a compact clamshell case. The Sony WH-1000XM5 does not fold inward (only lays flat), making the travel case somewhat larger.
How does battery life compare?
Sony comfortably wins with 30 hours of continuous playback with ANC enabled, compared to 24 hours on the Bose (or 18 hours with Immersive Audio spatial sound enabled).
