Bose QuietComfort Ultra Headphones vs Bose QuietComfort Headphones

Both are Bose over-ear headphones with active noise cancelling and Bluetooth, so the core experience is close. The first model lists 24 hours of battery life and comes in blue or black; the second comes only in gray and its runtime is not stated. Buy the first if battery life and color choice matter; buy the second only if you specifically want the gray finish. Owners of Bose over-ears generally praise the noise cancelling and comfort, and reviewers note the plastic build is light rather than premium.

• Choose the Bose BO8843671602 if you want a stated 24-hour battery rating and a choice of blue or black.
• Choose the Bose BO8843671702 if you want the gray colorway and battery runtime is not a deciding factor for you.
