Linsoul Martilo Hybrid IEM 1 Planar+2BA+2DD

The Martilo is a wired in‑ear monitor tuned for impactful bass and clear detail, aimed at listeners who want punch without losing clarity. It blends a sub‑bass shelf that emphasises low end with planar and balanced armature elements to keep treble air and midrange definition, making it useful for EDM, hip‑hop and monitoring on the move.

Key features

Hand‑assembled and built around a hybrid driver array, the Martilo pairs a dedicated planar driver for upper treble with dual Knowles RDE balanced armatures for midrange precision and dynamic drivers for low end. According to the manufacturer the sub‑bass shelf adds around 15dB of extension, so kick drums and basslines land with weight. Expect a rounded bass curvature that preserves low‑mid warmth while a 200Hz crossover helps avoid muddiness. The result is a sound with strong sub‑bass presence, articulated mids and airy treble response.

Why it’s worth it

If you prioritise bass impact, the Martilo delivers a focused low end while still preserving clarity in vocals and synths. The planar driver adds upper treble air so detailed elements sit clearly above the low‑end weight. You should be aware that the tuning favours basshead preferences, so if you prefer a neutral signature you may notice a warmer tilt.

Best use cases

Worth considering if you listen mainly to bass‑heavy genres, DJ previews or mobile monitoring and want a single pair that emphasises punch and presence. The detachable cable and modular plugs mean swapping to a balanced connection is straightforward if you move between devices. For everyday commuting and casual listening the Martilo offers robust build quality and a musical, engaging sound with a bass focus.
