Cavo adattatore helos USB 3.1 Type-C su 3,5 mm, modello 288381, argento

helos Premium audio adapter (model 288381) is a 10 cm cable that converts a USB-C (USB 3.1) port into a 3.5 mm stereo mini jack. Finished in silver with gold-plated contacts, the adapter allows connection of headphones, earphones or external speakers to devices that lack a dedicated headphone port. The cable uses thermoplastic elastomer (TPE) for the jacket and supports USB 3.1 audio transmission.

The TPE jacket offers flexibility and basic mechanical protection. The adapter is plug-and-play on devices that support audio over USB-C and is certified to the USB 3.1 specification.
