USB-C Wired In-Ear Headphones

The Sony IER-EX15C is a pair of wired in-ear headphones that connect via USB-C to phones, laptops and gaming consoles. Weighing 0.05 kilograms, they draw power from the host device so no battery is required. An in-line remote provides volume control, a multi-function button and a built-in microphone for calls and voice-assistant access.

Commuters and remote workers needing simple USB-C

The headset suits anyone who wants a lightweight, tangle-resistant cable and immediate plug-in operation without pairing or charging. Buyers whose devices lack a USB-C port or who prefer wireless freedom should look at something else. The single-ear coupling and 10 ohm impedance are tuned for everyday calls and music rather than critical monitoring.

10 ohm input impedance

At 10 ohms the headphones present an easy load for the USB-C audio output on most modern smartphones and laptops, delivering adequate volume without a separate amplifier. If your source device has a high-output-impedance jack or you need a higher-impedance load for specialised equipment, this model will not match that requirement.

Questions about this item

Does the USB-C connector draw noticeable power from my phone during all-day listening?

The headphones are passive and draw only the tiny current needed for the microphone and remote; they have no battery or active circuitry that would drain a phone noticeably.

What must my device already have for these headphones to work?

Your device needs a USB-C port that supports digital audio output; no separate DAC, adapter or driver installation is required.

Will the 10 ohm impedance and 600 ohm microphone impedance work properly with an older laptop that only has USB-A ports?

You would need a USB-A to USB-C adapter that carries digital audio; the headphones themselves present a standard USB audio interface once connected.
