Two-Pack Wired USB-C In-Ear Headphones
This twin pack supplies two white SIOODO SIO-C30 in-ear headphones with USB-C connectors. Each unit includes an inline microphone and push-button controls for playback, track skipping and call handling. The wired design draws power and audio directly from the host device.
Listeners wanting a spare pair for daily use
Buyers who prefer a single set or need wireless freedom should look elsewhere. The passive noise cancellation relies on physical seal rather than active circuitry, so users expecting electronic noise reduction will not find it here. The earphones are not water resistant.
32 ohm impedance with integrated DAC
The 32 ohm input impedance matches typical smartphone outputs, while the built-in digital-to-analogue converter handles the USB-C audio signal. This specification determines whether the earphones work with a given USB-C audio port.
