Sound Impressions: Bass
The Martini’s bass is precise, controlled, and punchy – tighter in character than you might expect from a BCD-inclusive tribrid. The 6mm liquid diaphragm dynamic driver keeps the mid-bass quick and clean, while the 10mm bone conduction driver adds a tactile, physical dimension to the low end that sits distinctly underneath the DD’s contribution. The sub-bass rumble has a satisfying depth to it, reaching deep without spilling or bloating into the lower mids. The BCD’s contribution here isn’t the loud, full-body holographic experience – it’s more of a precision sub-frequency reinforcement that adds physical sensation without thickening the overall low-end character.
The bass quantity sits at a mild v-shaped level, which is enough to satisfy most sub-bass enthusiasts without going into basshead territory. Agile and well-controlled decay keeps the bass from dragging, which makes for a clean, rhythmically accurate low end that benefits faster-tempo genres particularly well. There’s no lumpiness or uneven bass flow – the amplitude stays even throughout the low range with consistent texture. The Martini’s bass isn’t the kind that shakes the room, but it’s the kind that hits exactly where it needs to hit, every time.
Sound Impressions: Mids / Timbre
Martini’s 3:5:2 tuning concept sure seems to be counted into the tuning because vocals are the focal point of the overall sound. The 2 Knowles full-range BAs and 2 custom BAs create a mid-range that seamlessly bridges between lows and highs, nicely done with no audible gap or phase disconnect between the two. Vocals are also kept coherent and organic throughout the range, without metallic bites or tonal suck-ups.
Vocals sit in a slightly thicker body from neutral – not lean, not thick, but closer to the neutral side of the spectrum. It doesn’t give a distinctive full-bodied feel. What they lack in body, however, they make up for in clarity and articulation. The mids are highly resolving and breathable, with micro-detail retrieval that surfaces fine-grained textures in vocals and instruments without sounding forcefully over-exposed.
Timbre carries a neutral-warm character in the lower mids that gradually transitions to a slightly brighter, more transparent quality as it moves toward the upper mids – the tonal gradient from warm to bright is smooth and natural rather than abrupt. The vocals have a clean and crisp quality to them, particularly in the upper registers, where the custom BAs introduce a refreshing airiness. Sibilance is well-managed despite the brightness lean – the upper mids have enough crispness to feel lively and transparent without causing discomfort. Mids are not the most lush or emotionally thick in this price range, but they’re highly articulate and technically refined for the asking price.
Sound Impressions: Highs / Soundstage
Trebles are where Martini’s character becomes its most distinctive. The highs are sparkly, extended, and airy. They sit more prominently in the mix than the bass and contribute equally to the IEM’s overall energy. What’s nice about Martini’s trebles is that they sound prominent and silky without the typical roughness or graininess often found in BA drivers. The custom BA tweeters give highs a clean shimmer and fine-textured sparkle that is precise and well-defined. Details in the treble instruments are easy to pick out, and the extension goes deep enough into the upper registers to give the sound genuine air and openness. Brightness is present but stays within a comfortable boundary – those who are mercilessly treble-sensitive should take note, though by typical standards the highs here remain pleasant and non-fatiguing.
The soundstage is one of Martini’s stronger technical showings. Imaging is holographic and precise – instrument placement feels three-dimensional rather than confined to a flat horizontal plane. The pressure relief system likely contributes here, as the less-pressurized canal environment allows the staging to breathe more naturally. The width is adequate and well-distributed, and the depth perception is noticeably good for this price range. Separation is clean even in complex multi-instrument passages, keeping each element distinguishable without the stage feeling artificially carved up.
