Hi guys, here's my full review of the Punch Audio Portazo, an audiophile IEM tuned towards being a basshead IEM that I like very much. The Portazo is not just all about the bass, it's actually a very good all-rounder offering great soundstage and planar detail. This video also includes comparisons to the Kiwi Ears Septet and the SPA Hi-End Max.

About This Video

In this video I review the Punch Audio Portazo, which is a 1DD + 2 planar driver IEM that’s clearly tuned for bassheads—Portazo literally means “slam.” On my clone 711 coupler it measures with a big sub-bass shelf (marketing says +15dB, I’m seeing closer to ~+13dB), plus a healthier but still pretty controlled mid-bass lift, and a slightly scooped lower midrange. I also go through the unboxing (case, silicone + foam tips, spare mesh filters, modular cable with balanced and single-ended plugs) and talk about the all-plastic shell, resin-poured green faceplate, and that short, stubby nozzle design. Sound-wise, the Portazo surprised me at first. On classic rock and vocal pop it can come across more like a neutral U-shape because those tracks simply don’t have much sub-bass content. But once I switched to EDM, hip hop, and soundtracks (think Daft Punk and Hans Zimmer), the sub-bass boost becomes obvious: it slams fast and snappy, adds a deep thump, and then gets out of the way so the overall cleanliness stays intact. The treble is generally smooth and controlled with planar detail, and the soundstage is spacious with especially good depth and solid imaging. I also compare it to the SPA Hi-End Max and Kiwi Ears Septet, then wrap up with the main trade-offs: the short nozzle fit and the fact that the bass “effect” depends heavily on your library. If you want deep sub-bass without turning everything into a muddy mess—and you listen to sub-bass-heavy genres—the Portazo is a really well thought-out all-rounder for a basshead tuning.
