Compatibility and connection

These earbuds plug into a USB-C port and rely on the device’s support for USB-C digital audio / USB Audio Class. They work with many newer Chromebooks, tablets, phones, and laptops that output audio over USB-C. If a device’s USB-C port is charge-only or restricted by IT policy, audio may not pass through—so districts may want to confirm compatibility on their standard device model. :contentReference[oaicite:0]{index=0}
