What this adapter does

This Hetai Tech adapter converts a USB 3.1 Type-C port into a 3.5 mm female jack for headphones, speakers or a microphone. It is aimed at users of phones such as the P20 or P30 Pro that lack a built-in headphone socket and need a simple wired audio connection.

Behaviour during extended use

The short 12 cm cable keeps the signal path brief, which helps maintain audio quality during long listening sessions or calls. No active electronics are described, so performance depends on the host device’s own digital-to-analogue conversion and power delivery.

Installation notes

The reversible Type-C plug inserts either way up, so there is no need to check orientation before connecting. The only common issue is that some Type-C ports do not support analogue audio output, in which case the adapter will not work regardless of build quality.

Questions about this item

Does the 12 cm adapter draw noticeable power or get warm when used all day?

It is a passive 12 cm cable with no active electronics, so it draws negligible power and does not generate heat during continuous use.

What must my device already provide for the 3.5 mm jack to carry both headphone and microphone signals?

The host USB-C port must support analogue audio output and microphone input through the same 3.5 mm TRRS connection.

Will the adapter work with older headsets that use separate 3.5 mm plugs for audio and mic?

No, the single 3.5 mm female socket accepts only a combined TRRS plug; separate headphone and microphone plugs require an additional splitter.
