The SIVGA SM100 is a wired in-ear earphone with a 10 mm dual-chamber dynamic driver (PU + sapphire-like ceramic composite diaphragm) in zinc alloy shells, on a detachable 0.78 mm 2-pin cable with an in-line mic. It suits listeners who want one wired set for music, games and calls.
Who the SIVGA SM100 is for
Calls and voice chat: The cable carries a mic and a one-button remote that plays or pauses music, answers or ends calls and skips tracks.
Music and gaming: SIVGA describes the tuning as delicate treble, solid mids and impactful bass, and lists zero-latency wired transmission for games.
Phones without a headphone jack: The 3.5mm + USB-C Adapter version adds a USB-C to 3.5mm adapter, so the same earphones plug into a USB-C phone or laptop.
Long listening sessions: SIVGA shaped the shells from 3D ear scans and routes the cable over the ear, which it says reduces cable noise.
Skip it if: you want a carrying case or a range of tip sizes — SIVGA lists only two pairs of ear tips and a user manual alongside the earphones.
