I/O Sogno VS Punch Audio Martilo

I/O’s Sogno lands as a more Harman-esque, musical follow-up to the Vol with a punchy, dimensional bass that’s quick in attack and decay, slightly forward mids, and an upper end that can be nudged down with the right tips (stock tips run a touch brighter). Resolution is solid and the stage isn’t huge, but it never feels congested. The unboxing is class-leading for the $400 bracket: an all-resin shell with a beautiful faceplate, an interchangeable-termination cable, hard case with removable foam, pouch, and five full sets of tips. Fit is snug and lightweight, though the lower protrusion can cause minor irritation after ~4 hours.

For competitive gaming, tip choice is everything thanks to the “fish-mouth” nozzle. TW40 tips work well in Valorant, while third-party AZLA SednaEarfit ORIGIN tame the hot 2–4 kHz band in Apex and COD so gunfire doesn’t mask shuffles, climbs, and utility cues. With the ORIGIN tips, separation, verticality, and imaging lock in nicely; microdetail and depth read (front/back/over/under) still leave a little on the table, keeping Sogno at a strong B on the Wallhack-Certified tier list—on the cusp of B+ with perfect synergy. Footsteps and positional cues remain clear even while shooting, bass stays controlled, though aerial killstreaks in COD can sound a bit abrasive. Net: an excellent music-first IEM that crosses over well for ranked play if you roll the right tips.

I/O Sogno aims for big “perceived value” at $400: a robust, watch-style carry case, an unusually rich ear-tip kit (multiple five styles neatly boxed, including foam and wide-bore variants), and a swappable-termination cable (3.5mm to 4.4mm) with tidy hardware and standard recessed 2-pin. The shell mirrors the Volare—medium-large with a longish nozzle—and the semi-custom shape sits securely enough but feels a bit wedge-like, not deeply locked behind the anti-tragus. Build and accessories are excellent for the price; comfort is fine, if a touch chunky.

Sonically it’s very Harman-compliant: a mostly sub-bass lift, leaner mids with forward vocals, and a treble that follows the target’s gentle roll-off. That tuning makes the Sogno sound dry and somewhat narrow/congested; cymbals and hi-hats lack shimmer (a slightly “plasticky” timbre), and staging isn’t especially open. Versus Volare, Sogno is less warm and less airy; versus Truthear Nova it hits a bit harder down low but remains similarly clinical; and value pressure comes from cheaper sets like the 7Hz Zero. In direct comparison, Moondrop × Crinacle Dusk (also below this price) feels miles ahead in technicalities and overall engagement. A solid, accessory-rich Harman option, but not quite the “dream” its name suggests—overall 3/5.

Boom — time for bass. Punch Audio’s Martilo is a tribrid (2×8 mm DD + 2 BA + 1 micro planar) coming in around $330. The package is stacked: sturdy square case, extra filters, multiple tip sets, and a genuinely excellent modular 3.5/4.4 cable that lays flat, has no microphonics, and a firm chin slider. The shells are ergonomic with venting, metal nozzles with a proper lip, and a small nozzle diameter (5.9/5.0 mm) that helps seal; comfort and passive isolation are both strong.

Sonically, this is unapologetically bass-focused without being bass-only. Expect massive sub-bass depth and a punchy mid-bass, yet the low end stays tight, controlled, textured and doesn’t bleed. Mids retain clarity with non-shouty presence, while treble is crisp, smooth, non-fatiguing with decent extension (not ultra-airy). For a bass-heavy set, technical performance is solid: detail is good, and imaging/separation keep busy tracks coherent and energetic.

Against Hisenior’s Mega5EST Bass Plus, Martilo hits harder, feels more engaging, and offers better vocal clarity — and it steamrolls on value at the lower price. Compared with Xenns Tea Pro, the Tea Pro is a bass-lover all-rounder that spotlights vocals/instruments more; Martilo goes full bass-head with bigger rumble and impact. Ideal for listeners who crave deep slam but still want clarity, comfort, and great accessories; not for neutral/reference chasers. Final verdict: 4/5 — it truly punches above its price.

The Punch Audio Martilo shows up screaming BASSHEAD on the box, but the tuning is smarter than that. A hybrid stack—2×8 mm DD + 2×BA + 1 planar—delivers bass that hits when the track calls for it, then gets out of the way. The surprise is the huge soundstage: airy, wide, borderline cinematic, so pianos, crowds, and live recordings feel expansive rather than claustrophobic. Low 9 Ω impedance and easy efficiency keep the power demands chill, though a low-impedance cable is recommended.

Tip rolling matters. With thin-wall silicone (e.g., Dunu S&S) the stage opens up and balance feels right; foams and some wide-bore options can push treble into a slightly sharp zone on certain tracks. Tonality reads clean and natural—warm-adjacent without a blanket—so everyday music stays unbloated, while proper sub-bass test tracks pressurize with that “firm hand on the chest,” not a sledgehammer.

Build is solid: thick, comfy modular cable with swappable plugs, flashy red shells, and a comically oversized box for a modest accessory set (silicone + foams). Street price around $330 lands in the sweet spot—easily justifying $375 by ear. Think “poor man’s Mega 5 EST Bass Plus”: similarly satisfying slam and stage, with the pricier set showing a touch more upper-mid/treble refinement. Not just for bassheads—more like a full-range thrill ride that lets music breathe and hit when it should.
