USB-C Audio Transducer for Single-Port Phones
This btin-20210005 adapter connects 3.5 mm headphones to USB-C devices. It targets users whose phones lack a dedicated audio jack. The splitter design allows simultaneous charging and listening. It is compatible with Pixel, Samsung, Huawei, Sony and HTC handsets.
Thermals Noise and Power Draw
Passive circuitry generates no audible noise during playback. The integrated smart chip regulates signal transmission without active cooling. Power is drawn only from the host port to drive the audio stage. No external supply or battery is required for operation.
Bundled Accessories and Software Impact
The package supplies the adapter cable only; no driver disc or configuration utility is included. Hi-Res audio support is handled by the onboard chip automatically. TPE jacket survives an 8.0 kg tensile test for cable durability. Volume and call controls function immediately on supported devices.

Questions about this item
How do I plug the USB-C end so the inline remote and microphone on my 3.5 mm headset actually work?
Insert the USB-C connector fully until it clicks; the built-in smart chip then activates the CTIA wiring so the remote and mic function — a partial insertion leaves them dead.
What part of the btin-20210005 is most likely to wear out first?
The TPE cable jacket is rated to an 8.0 kg tensile test, but repeated sharp bends near the splitter housing will fatigue the internal conductors before the jacket shows damage.
At what point does audio quality degrade during a long listening session?
The smart chip maintains Hi-Res signal integrity until the phone’s USB-C port throttles power output, which typically happens first during sustained high-volume playback while fast-charging.
