Wired USB-C listening

The SMS Audio Sudio V3BLK are wired in-ear headphones that connect through a USB-C plug, so they draw power directly from the host device and never need charging. The 10 mm dynamic drivers present a 32 ohm load, making them easy to drive from phones, tablets or laptops. At 14 grams they add negligible weight for commuters or office workers who want a simple plug-and-play solution.

Steady performance over time

Because the earbuds are passive and draw no battery, their output stays consistent for the entire listening session without voltage sag or thermal throttling. The braided cable resists tangling and reduces microphonic noise when the cord moves against clothing. IPX4 splash resistance means light rain or sweat will not interrupt playback during long days.

Built for daily handling

Physical buttons on the cable give tactile control of volume, playback and calls without relying on touch surfaces that can misfire in cold or wet conditions. The integrated microphone has a 3K ohm impedance suited for voice pickup in typical indoor or outdoor environments. Buyers who want wireless freedom or active noise cancellation should look elsewhere, as this model omits both.

Questions about this item

How much heat or battery drain should I expect from the 10 mm drivers during all-day use?

The earbuds draw power directly from the USB-C port, so there is no internal battery to drain and the 10 mm dynamic drivers produce no noticeable heat during extended listening sessions.

What must my device provide for the USB-C connector and inline microphone to work?

Your device needs a USB-C port that supports digital audio output and the standard USB audio class so the built-in microphone and 32 ohm drivers can function without extra drivers.

Will the 32 ohm impedance and USB-C digital connection work reliably with an older laptop that only has USB-A ports?

You would need an active USB-A to USB-C adapter that carries digital audio; a passive cable will not work because the earbuds require a digital USB-C audio source rather than an analogue jack.
