Pebble USB-C audio adapter with ALC4050

The ApeSonic Pebble converts a USB-C port into a 3.5 mm analogue output using a Realtek ALC4050 DAC and a Class G amplifier. It is built for listeners who want higher-resolution playback from phones or laptops that lack a native headphone jack. The aluminium shell and 5 cm braided cable keep the dongle compact for mobile use.

32-bit 384 kHz headroom and 150 ohm drive limit

The adapter accepts PCM streams up to 32-bit 384 kHz, so high-resolution files play without down-sampling. Its Class G amplifier drives loads up to 150 ohms cleanly, covering most portable headphones and many desktop models. Headphones with higher impedance or very low sensitivity will not reach loud volumes.

Driver-free operation and cap-less output

The device is plug-and-play compliant with Windows, requiring no driver installation. A cap-less output stage removes DC-blocking capacitors from the signal path, reducing component count and potential colouration. The 5N pure copper cable and textured jacket are the only bundled accessories; no software suite or additional adapters are included.

Questions about this item

Will the ApeSonic Pebble adapter work with my existing 150-ohm headphones?

The adapter uses a Realtek ALC4050 chipset and Class G amplifier; 150-ohm headphones may not reach high volume levels.

How can I verify the ApeSonic Pebble is delivering 32-bit 384 kHz audio after plugging it in?

Check your operating system sound settings or playback software; it should report 32-bit depth and 384 kHz sample rate when playing Hi-Res files.

Does the ApeSonic Pebble box include any extra cables or adapters besides the 5 cm USB-C to 3.5 mm unit?

The product is sold as a single 5 cm USB-C to 3.5 mm adapter with aluminium casing and texture cable; no additional accessories are included.
