In this video I review the Punch Audio Martilo, a brand-new hybrid IEM from a newcomer that basically showed up out of nowhere and decided to go full “bass head” on their first swing. And yes—this thing absolutely punches. I walk through the unboxing (including the peek-a-boo doors and the pleather pouch), the accessories (cable with 3.5 and 4.4 plugs, silicone tips, and a full set of foamies), and my thoughts on the build. It’s plastic, so it’s light and comfy, but don’t go sitting on it—this isn’t the kind of shell I’d trust against abuse. Sound-wise, the Martilo is bass head through and through: huge sub-bass and mid-bass with a satisfying, dynamic slam that’s awesome for movies and DJ remix tracks. The key point is that it doesn’t let the mids turn into a smeary mess—upper mids are balanced enough to keep vocals defined and natural, with female vocals getting a bit of sparkle and male vocals sounding weighty. Treble extends well enough to add texture and air without stealing the spotlight from the bass. I also compare it to the FatFreq Deuce (Martilo is simply better and cleaner) and the 7Hz Legato (cheaper, more boombox character). My ratings land at 7.5 for bass, 7.5 mids, 7 treble, 7 resolution, 6.5 stage, and an A- for enjoyment.
