Pubiohs USB-C Splitter 3.5mm & USB-C Charging

Pubiohs USB-C Splitter 1 in 2 out is a compact adapter that splits one USB-C port into a 3.5mm audio jack, a USB-C headphone/data port, and a USB-C 10W charging port — built for digital USB-C headphones, calls, charging and data transfer.

Modern phones, tablets and laptops often trade the 3.5mm jack for USB‑C audio or single‑port designs. This Pubiohs adapter gives you three useful connections from one USB‑C male plug so you can listen with digital headphones, plug in a microphone-enabled headset, charge at up to 10W, and move files — all without swapping cables. Read the short compatibility notes and quick tips below to make sure your headphones are digital‑audio compatible before buying.

How does the splitter let me listen and charge at the same time?

The adapter presents three female ports: a 3.5mm analog-style jack (for devices that accept a digital-to-analog path), a USB‑C headphone/data port (for digital USB‑C headsets), and a USB‑C charging port that supports up to 10W. Note that only one audio output can be active at a time, and the charging port can be used simultaneously with the selected audio port.

• One USB‑C male input connects to your device.
• USB‑C charging port supplies up to 10W while audio is in use.
• Select either the 3.5mm jack or the USB‑C headphone jack for sound — not both.
• Plug and play on devices that accept external USB audio.

Will this adapter work with my headphones and mic?

It works only with digital USB‑C headphones or headsets that enumerate as a USB audio device. If your headset is analog-only, this adapter will not provide audio. The adapter supports microphone input and volume control with compatible digital headsets.

• Check that your headphones appear as a USB audio device on your device (e.g., a USB‑C iPad Pro or MacBook).
• Microphone and inline controls function when the headset supports USB audio/mic.
• If first-time connection produces no sound, select the device audio output labeled "USB Audio 2.0" or similar in the system's sound settings.

Can I transfer files while listening and charging?

Yes — the Pubiohs splitter includes a data-capable USB‑C headphone/data port that allows file transfers while you use audio or charge. This is useful for backing up media or syncing without unplugging accessories.

• Data transfer uses the USB‑C headphone/data port while audio plays from the selected audio output.
• Simultaneous charging and data transfer are supported through the dedicated charging port and the data port, respectively.
• Works best with devices that support external USB audio and standard USB data protocols.

Is the audio quality good enough for high-resolution music?

Yes — the adapter uses an internal digital-to-analog conversion path and DAC chips capable of up to 32‑bit/384kHz processing, aiming for clearer playback and lower distortion versus lower-spec adapters. This helps reduce static and improves clarity for digital headphone users.

• Built-in DAC supports high-resolution audio formats up to 32‑bit/384kHz.
• Engineered to minimize current noise and distortion for cleaner output.
• Performance depends on the source device and the connected headphones' capabilities.

Who is this for? The Pubiohs USB‑C Splitter is best for people who use digital USB‑C headsets and need to charge, talk, or transfer files without swapping cables — frequent travelers, students, and professionals who work from tablets or laptops with a single USB‑C port. Avoid purchasing if your headset is analog-only; verify compatibility by confirming your headphone shows up as a USB audio device on a compatible host before buying.
