Detachable cables make it easier to swap devices and replace worn parts. Multiple reviews note that some features and controls are reduced or unavailable when using the analog 3.5mm path.
Having both USB and analog wired paths adds versatility and makes the headset usable even when the battery is low. The main caveat is that using a wired connection can override wireless features, which limits simultaneous use cases.
Detachable cables and USB-C audio add flexibility for laptops and in-flight systems, even without a native 3.5mm jack on the earcup. Most reviews note the headphones typically need to be powered on for wired listening.
The lack of a 3.5mm input is commonly noted. Some reviewers are fine using USB-C audio, but it still reduces compatibility with airplane adapters and analog sources.
