What it is and who it is for

USB-C wired in-ear headphones with an inline microphone and remote control. Designed for listeners who want a single cable connection to phones, tablets or laptops that lack a 3.5 mm jack. The 24-bit/96 kHz DAC delivers high-resolution stereo audio for music, podcasts and calls. Not suited for buyers who need wireless freedom or a traditional analogue plug.

Practical limits of the USB-C interface

Audio and power travel over the same USB-C port, so the host device must support digital audio output through that connector. Passive noise isolation depends on a good ear-tip seal rather than active cancellation. The cable length is fixed, which restricts movement compared with wireless alternatives. No analogue fallback exists if the port does not implement the required audio class.

Installation ease and common issues

Plug the USB-C connector into a compatible port and the headphones are recognised immediately without drivers. Inline buttons handle volume, playback and call answering on most supported devices. A frequent issue is partial button mapping on certain Android or iOS models where volume controls may not respond. Ensure the port is clean and fully seated to avoid intermittent audio or microphone drop-outs.

Questions about this item

Should I pick the ESC01 in black or is another colour offered?

The ESC01 is supplied only in black, so there is no alternative colour to choose from.

What does the 24-bit/96 kHz rating mean when I plug these into my phone?

It means the built-in DAC can decode high-resolution audio up to 24-bit depth and 96 kHz sample rate, delivering detail beyond standard CD quality.

Does the USB-C connector limit volume or audio quality compared with a 3.5 mm jack?

The USB-C plug carries digital audio to the earbuds' own DAC, so volume and fidelity depend on that internal converter rather than the host device's headphone socket.
