USB-C audio and charging adapter

This USB Type-C to 3.5 mm jack adapter lets you connect wired headphones to phones that lack a headphone socket. It carries analogue audio through a dual decoder chip while simultaneously passing power for fast charging. The cable suits owners of Samsung Galaxy S8, S9 or Note 10 models who want to listen and charge at the same time. It is a compact accessory for daily commuting or desk use.

Thermals noise and power draw

The adapter draws power only for the audio circuitry and the charging pass-through, so it adds negligible heat to the phone. No fan or active cooling is present, making operation completely silent. Power consumption stays within the USB-C port’s standard limits during music playback and charging. Normal use produces no audible hiss or interference thanks to the upgraded dual decoder chip.

Dual decoder chip for clean audio

The defining specification is the upgraded dual decoder chip that separates audio decoding from the charging path. This design prevents the noise interference that single-chip adapters often introduce when the phone is charging. Buyers who need a simple USB-C to 3.5 mm cable without simultaneous charging should look elsewhere, as this model is built specifically for combined audio and power delivery.

Questions about this item

How do I connect this USB-C to 3.5mm adapter to my phone and what step causes audio issues?

Plug the USB-C end into the phone and the 3.5mm jack into your headphones; the dual decoder chip handles audio conversion automatically, but forgetting to seat both plugs fully is the step that causes static or no sound.

Will the USB-C port or the 3.5mm jack wear out first with daily plugging and unplugging?

The 3.5mm jack typically shows wear before the USB-C port because its spring contacts fatigue faster than the USB-C connector's rated insertion cycles.

At what point does sustained music playback and charging cause the adapter to throttle or cut out?

The upgraded dual decoder chip maintains stable Hi-Fi output during continuous use, and the safe fast-charging circuit prevents battery stress, so thermal limits are reached only after extended high-volume sessions.
