Design & Features

The Utility version preserves the slim metal headband, the adjustable “ComfortZone” slider, and fold-up form factor that made the original so portable. But the major upgrade is interchangeable cable options: you can swap in connectors (USB-C, Lightning, traditional 3.5 mm) depending on your device. Stereoindex+2StereoTech+2

This modularity means you’re not stuck with one plug type—and Koss sells separate cables so you can future-proof against device changes. Stereoindex+1

Sound & Performance

True to its heritage, the Porta Pro Utility largely retains the original Porta Pro’s sound signature. The low frequencies are present (though not hyper precise), the midrange is lucid and serviceable, and the treble is “tamed”—smooth rather than raw or piercing. StereoTech+1 Reviewers often describe the upper range as “simplified” or “clamped,” leaning toward listenable comfort rather than analytical detail. StereoTech

The open / semi-open styling helps produce a sense of space or “airiness,” making for a less claustrophobic soundstage. Stereoindex+1 That said, due to its design, it doesn’t isolate you from ambient noise.
