Neutral-leaning flathead earbud with clear vocals and airy treble; sub-bass is light and benefits from a warmer source or a touch of EQ. Airy treble, open stage and clear vocals with tasteful neutral bass; handsome ebony-wood build. Limited sub-bass presence and body; may rely on volume, warmer sources or EQ to add weight to the low end.
Youtube Video Summary

The M300 is a flathead earbud in ebony wood shells with a 15.4 mm dynamic driver; in hand it feels solid and well finished. Tuning leans neutral with a flatter low end that supports the lower mids, lifts vocal energy modestly, and carries into an airy treble with good extension, yielding a natural sense of stage. The presentation emphasizes clarity and openness rather than warmth or heavy slam.

Bass focuses on mid-bass texture and impact more than sub-bass rumble, with some roll-off; turning volume up or pairing with a warmer source/EQ adds body if desired. Mids come forward cleanly with balanced male and female vocals, while the upper range stays extended without sounding peaky, contributing to stage height and resolving power. A light lift to sub-bass can yield a fuller balance without masking the well-extended top end, but even stock the M300 delivers a tasteful, open and controlled listen for an earbud form factor.

Although often grouped with IEMs in shops, the Sivga M300 is a flat-head earbud with an open fit. It combines CNC-machined aluminum and African ebony housings around a 15.4 mm dynamic driver (graphene-coated diaphragm). .

Key specs include 64 Ω impedance, 109 dB sensitivity, a rated 20 Hz–40 kHz response, and a fixed silver-plated OFC cable; weight is listed at 29 g. Street pricing sits around $64.90, placing it firmly in the budget segment. .

On performance, product descriptions and early impressions point to a warm-balanced tilt with punchy bass, clear vocals, and a notably wide, airy stage for the price—consistent with the open earbud form factor (with limited isolation and bass depth depending on foams/fit). An independent write-up also highlights build quality, comfort, and surprisingly cohesive sound at this price point.
