| Connection | Cable Included | Key Benefits | |------------|----------------|--------------| | USB-C | Yes | Digital audio, charges while playing | | 3.5mm analog | Yes | Universal compatibility, works at 0% battery |
The 1st Gen only used USB-C for charging. The 2nd Gen now supports full audio playback over USB-C.
Advantages:

The traditional 3.5mm cable provides universal compatibility.
Best for: Airplane entertainment systems, older devices, or emergency use when battery is depleted.
