Sennheiser / SPECIFICATION-BASED RESEARCH
Over-ear headphones with adaptive noise cancellation and a transparency mode. Sennheiser lists up to 60 hours of playback under its test conditions.
Consider these if a long stated battery runtime is a priority for travel or repeated daily use.
The battery figure is a manufacturer claim, not a like-for-like test against other headphones. Fit and sound preferences still need a personal check.
